== Coverage details ==

=== RTL-SDR Blog (2026-10-29) ===

* '''Link:''' https://www.rtl-sdr.com/simtx-a-multiplayer-shortwave-radio-simulator-with-realistic-propagation-and-rtl_tcp-support/
* '''Summary:''' Short news post introducing SimTX as an open-beta multiplayer shortwave simulator in which all users share one simulated band. It lists the propagation stack (IRI-2020 with live ionosonde data, ITU-R groundwave and noise, Watterson fading), the transmit sources (mic, audio file, GNU Radio IQ), the supported modes and the virtual satellites. It highlights the local rtl_tcp bridge that lets SDR++ and similar programs tune the simulated band.
* '''Notes:''' States that the software does not appear to be open source. Embeds the official demo video (Amsterdam to Budapest, 1145 km). This post is the source for the TechSpeeltuin brief below.

* '''Author:''' 9M2PJU
* '''Summary:''' The most detailed third-party guide so far. It covers:
** the "hear it" audio clips (clean rig, overdriven rig, calm band, Kp 7.5 storm)
** a modulation-mode reference table
** propagation basics (groundwave, skywave, skip zone, LUF/MUF, NVIS, grey line)
** desktop app vs legacy Java client, with a download table
** a five-step first-transmission walkthrough
** stations and satellites
** receiving with SDR++
** Lua extensions, CLI and API
** accounts and community

* '''Link:''' https://techspeeltuin.nl/hamnieuws/2262/simtx-biedt-realistische-propagatie-in-multiplayer-simulator
* '''Summary:''' Three-paragraph Dutch news brief. It covers the shared virtual spectrum, the propagation models, the transmit modes, the rtl_tcp bridge, Windows/macOS/Linux support, Discord accounts and the Amsterdam to Budapest demo.
* '''Notes:''' Labelled as written by the site's AI editorial desk. It credits RTL-SDR Blog as its source and adds no new reporting.

=== NextTechWorld (2026-10-30) ===

* '''Link:''' https://nexttechworld.com/ham-radio/simtx-shortwave-radio-simulator/
* '''Summary:''' Long analytical feature (about 25 minutes reading time) discussing SimTX as a shared virtual RF medium rather than a voice-chat style app. Topics include:
** the shared-spectrum design
** IRI-2020 plus ionosonde assimilation, and the limits of empirical models
** Watterson fading, Doppler and multipath
** ITU-R noise and groundwave
** transmitter modelling (PA compression, heating, splatter)
** rtl_tcp and GNU Radio as an architectural choice
** FT8/WSPR and virtual satellites
** use in training
** open questions: model validation, scaling, latency and the lack of published source code

* '''Link:''' https://radiomesh.pl/krotkofalarstwo/kazdy-moze-nadawac-nic-nie-idzie-w-eter-simtx-symuluje-fale-krotkie/
* '''Author:''' MarWoj (SP9MAW)
* '''Summary:''' Polish hands-on article (about 6 minutes reading time). It explains how to listen with SDR++ and how to set up your own receiver and station. It covers the antenna options and NEC import, how the server computes each path, an SNR-threshold table by mode, satellites, and the terms of service (pirate and numbers stations and jamming are allowed within limits; unlicensed music and impersonating real stations are not).
* '''Facts reported that other coverage does not include:'''
** open beta since 14 August 2026
** download page offered version 0.1.0-alpha-16 on 1 November 2026
** run by a single private individual in Hungary
** accounts can be created by e-mail with a code login since 1 November 2026 (previously Discord only)
** a public receiver in simulated Budapest that needs no account (<code>argon.simtx.net</code>, port 1240)
** minimum age 13, with parental consent for minors
** the author notes the demo video's route, levels, storm, clock and overdriven transmitter were set by script, and calls it a demonstration
** a licence is only needed if the simulator's audio is fed into a real transmitter

	Later, on '''July 20''', Zynden's Random Music changed its name to '''Zynden's Radio 7.38''' to reflect that the station now broadcasted on 7.38 MHz exclusively. At this point, the station no longer just blasted music; it also began sending images via '''MFSK, DRM (EasyPal), SSTV, and KG-STV'''. On '''July 22''', the station became a official licenced station then renamed itself one final time (potentially) to '''Zynden's Radio Z or WZYN''', which later became its most recognizable name.

	The '''International Space Station''' ('''ISS''') is a space station in low Earth orbit (LEO). It is the product of the International Space Station program and is operated by five partner space agencies: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It is the first space station built, maintained and crewed through international cooperation and the largest human spacecraft ever constructed. It is an orbital research station, where scientific experiments in microgravity are conducted and the space environment is studied. Since 2 November 2000, it has hosted the longest continuous human presence in space. Alongside China's ''Tiangong'', it is one of two currently operational space stations.

			For decades, space enthusiasts have dreamed of communicating with astronauts. However, one of the most exciting and accessible ways to connect with the International Space Station (ISS) does not require a license or expensive gear. Through Slow-Scan Television (SSTV) transmissions, anyone on Earth can receive static images broadcast directly from the space station using a basic radio receiver or even a smartphone.
			What is ISS SSTV?
			Slow-Scan Television is an amateur radio transmission protocol that converts still images into audio tones. Instead of the massive bandwidth required to stream live video, SSTV compresses a single picture into a narrow voice channel. When these audio tones are picked up on Earth, software translates the shifting pitches back into lines of color, building an image piece by piece on a screen over the course of a few minutes.
			These broadcasts are organized by the Amateur Radio on the International Space Station (ARISS) program. They usually coincide with space exploration milestones, student educational events, or historical anniversaries. When active, the onboard transceiver automatically broadcasts a picture, rests for a couple of minutes, and then sends the next image in a continuous cycle.

			== Station details ==

			The station orbits between 51.64° north and south, at about 400km above Earth, below the Van Allen radiation belts and most space debris. Its orbit takes it at 7.67km/s roughly every 93 minutes around Earth, daily orbits 15.5 times a day. Measuring 358ft (with solar arrays) by 239ft, it is as large as a full-sized football or soccer field, and has a pressurised internal volume of 1,005 m<sup>3</sup> (35,491 ft<sup>3</sup>), comparable to a Boeing 747 airliner.

	The station is a modular space station divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. The Integrated Truss Structure connects the station's vast system of solar panels and radiators to its 16 major pressurized modules. These modules support scientific research, crew habitation, storage, spacecraft control, and airlock operations. The ISS has eight docking and berthing ports for visiting spacecraft. In total, the station consists of 43 different modules and elements. Crews visit via the Soyuz and Crew Dragon spacecraft, and previously the Space Shuttle. Cargo supply craft include Progress, Cargo Dragon, Cygnus, Automated Transfer Vehicle, and HTV-X.

	The ISS is the political product of the development of international cooperation in space throughout the space age. The station combines two previously planned crewed Earth-orbiting stations: the United States' Space Station ''Freedom'' and the Soviet Union's ''Mir-2''. The first ISS module was launched in 1998, with major components delivered by Proton, Soyuz and Space Shuttle launch vehicles. Long-term occupancy began with the arrival of the Expedition 1 crew on 2 November 2000. Since then, the ISS has remained continuously inhabited ~~for {{age in years and days\|~~2 November 2000~~\|sep=and}}~~, the longest continuous human presence in space. {{As of\|2025\|08}}, 290 individuals from 26 countries had visited the station.

	Future plans for the ISS include the addition of at least one module, the Payload Power Thermal Module by Axiom Space, forming the commercial segment of the station. The station is expected to remain operational until the end of 2030, by which parts of it are to be used for Axiom Station and the Russian Orbital Station. After this the ISS is planned to be de-orbited using the US Deorbit Vehicle, but critique of this plan and the proposal of parking the station at a more stable higher orbit has gathered congressional support {{as of\|2026~~\|lc=y}}~~.

[[File:500px-NOAA-M.jpg|thumb|Launch of NOAA-15]]
'''NOAA-15''', also known as '''NOAA-K''' before launch, was a polar-orbiting, NASA-provided Television Infrared Observation Satellite (TIROS) series weather forecasting satellite operated by National Oceanic and Atmospheric Administration (NOAA). NOAA-15 was the latest in the Advanced TIROS-N (ATN) series. It provided support to environmental monitoring by complementing the NOAA/NESS Geostationary Operational Environmental Satellite program (GOES).

== Launch ==
[[File:T2 07 G12 NOAA-K.jpg|thumb|Launch of NOAA-15]]
It was launched by the Titan 23G launch vehicle on 13 May 1998 at 15:52:04 UTC from Vandenberg Air Force Base, at Vandenberg Space Launch Complex 4 (SLW-4W), NOAA-15 replaced the decommissioned NOAA-12 in an afternoon equator-crossing orbit and is in 2021 semi-operational, in a Sun-synchronous orbit (SSO), at 808.0 km above the Earth, orbiting every 101.20 minutes.

== Spacecraft ==
The goal of the NOAA/NESS polar orbiting program is to provide output products used in meteorological prediction and warning, oceanographic and hydrologic services, and space environment monitoring. The NOAA-I Advanced TIROS-N spacecraft is based on the Defense Meteorological Satellite Program (DMSP Block 5D) spacecraft and is modified version of the TIROS-N spacecraft (NOAA-1 to NOAA-5). The spacecraft structure consists of four components: 1° the Reaction System Support (RSS); 2° the Equipment Support Module (ESM), which has been expanded from the TIROS-N design; 3° the Instrument Mounting Platform (IMP); and 4° the Solar Array (SA).

== Instruments ==
All of the instruments are located on the ESM and the IMP. The spacecraft power is provided by a direct energy transfer system from the single solar array which consists of eight panels of solar cells. The power system for the Advanced TIROS-N has been upgraded from the previous TIROS-N design. The in-orbit Attitude Determination and Control Subsystem (ADACS) provides three-axis pointing control by controlling torque in three mutually orthogonal momentum wheels with input from the Earth Sensor Assembly (ESA) for pitch, roll, and yaw updates. The ADACS controls the spacecraft attitude so that orientation of the three axes is maintained to within ± 0.2° and pitch, roll, and yaw to within 0.1°. The ADACS consists of the Earth Sensor Assembly (ESA), the Sun Sensor Assembly (SSA), four Reaction Wheel Assemblies (RWA), two roll/yaw coils (RYC), two pitch torqueing coils (PTC), four gyros, and computer software for data processing.

Instruments were flown for imaging and measurement of the atmosphere of Earth, its surface, and cloud cover, including Earth radiation, atmospheric ozone, aerosol distribution, sea surface temperature, vertical temperature and water profiles in the troposphere and stratosphere; measurement of proton and electron flux at orbit altitude, and remote platform data collection, and for SARSAT. They included: 1° an improved six-channel Advanced Very High Resolution Radiometer (AVHRR/3); 2° an improved High Resolution Infrared Radiation Sounder (HIRS/3); 3° the Search and Rescue Satellite Aided Tracking System (SARSAT), which consists of the Search and Rescue Repeater (SARR) and the Search and Rescue Processor (SARP-2); 4° the French/CNES-provided improved ARGOS Data Collection System (DCS-2); and 5° the Advanced Microwave Sounding Units (AMSUs), which replaced the previous MSU and SSU instruments to become the first in the NOAA series to support dedicated microwave measurements of temperature, moisture, surface and hydrological studies in cloudy regions where visible and infrared instruments have decreased capability.

=== Advanced Very High Resolution Radiometer (AVHRR/3) ===
[[File:AVHRR3 instrument.jpg|NOAA AVHRR/3 Instrument]]
The AVHRR/3 on the Advanced TIROS-N NOAA K-N series of polar orbiting meteorological satellites is an improved instrument over previous AVHRRs. The AVHRR/3 adds a sixth channel and is a cross-track scanning instrument providing imaging and radiometric data in the visible, near-IR and infrared of the same area on the Earth. Data from the visible and near-IR channels provide information on vegetation, clouds, snow, and ice. Data from the near-IR and thermal channels provide information on the land and ocean surface temperature and radiative properties of clouds. Only five channels can be transmitted simultaneously with channels 3A and 3B being switched for day/night operation. The instrument produces data in High Resolution Picture Transmission (HRPT) mode at 1.1 km resolution or in Automatic Picture Transmission (APT) mode at a reduced resolution of 4 km. The AVHRR/3 scans 55.4° per scan line on either side of the orbital track and scans 360 lines per minute. The six channels are: 1) channel 1, visible (0.58-0.68 μm); 2) channel 2, near-IR (0.725-1.0 μm); 3) channel 3A, near-IR (1.58-1.64 μm); 4) channel 3B, infrared (3.55-3.93 μm); 5) channel 4, infrared (10.3-11.3 μm); and 6) channel 5 (11.5-12.5 μm).

=== High Resolution Infrared Sounder (HIRS/3) ===
[[File:HIRS 4 instrument.jpg|The HIRS/4 Satellite Instrament]]
The improved High Resolution Infrared Sounder/3 (HIRS/3) on the Advanced TIROS-N (ATN) NOAA K-N series of polar orbiting meteorological satellites is a 20-channel, step-scanned, visible and IR spectrometer designed to provide atmospheric temperature and moisture profiles. The HIRS/3 instrument is basically identical to the HIRS/2 flown on previous spacecraft except for changes in six spectral bands to improve the sounding accuracy. The HIRS/3 is used to derive water vapor, ozone, and cloud liquid water content. The instrument scans 49.5° on either side of the orbital track with a ground resolution at nadir of 17.4 km. The instrument produces 56 IFOVs for each 1,125 km scan line at 42 km between IFOVs along-track. The instrument consists of 19 IR and 1 visible channel centered at 14.95, 14.71, 14.49, 14.22, 13.97, 13.64, 13.35, 11.11, 9.71, 12.45, 7.33, 6.52, 4.57, 4.52, 4.47, 4.45, 4.13, 4.0, 3.76, and 0.69 μm.

=== Advanced Microwave Sounding Unit (AMSU-A) ===
The AMSU is a new instrument on the Advanced TIROS-N (ATN) NOAA K-N series of operational meteorological satellites. The AMSU consists of two functionally independent units, AMSU-A and AMSU-B. The AMSU-A is a line-scan instrument designed to measure scene radiance in 15 channels, ranging from 23.8 to 89 GHz, to derive atmospheric temperature profiles from the Earth's surface to about 3 millibar pressure height. The instrument is a total power system having a field of view (FOV) of 3.3° at half-power points. The antenna provides cross track scan 50 degrees on either side of the orbital track at nadir with a total of 30 IFOVs per scan line. The AMSU-A is calibrated on-board using a blackbody and space as references. The AMSU-A is physically divided into two separate modules which interface independently with the spacecraft.

[[https://en.wikipedia.org/wiki/File:AMSU-B_Diagram.png|thumb|A diagram of the AMSU-B instrament]]
The AMSU is a new instrument on the Advanced TIROS-N (ATN) NOAA K-N series of operational meteorological satellites. The AMSU consists of two functionally independent units, AMSU-A and AMSU-B. The AMSU-B is a line-scan instrument designed to measure scene radiance in five channels, ranging from 89 GHz to 183 GHz for the computation of atmospheric water vapor profiles. The AMSU-B is a total power system with a FOV of 1.1° at half-power points. The antenna provides a cross-track scan, scanning 50° on either side of the orbital track with 90 IFOVs per scan line at approximately 22.5 scans per minute. One scan line is completed in 2.67 seconds. On-board calibration is accomplished with blackbody targets and space as references. The AMSU-B channels at the center frequency (GHz) are: 90, 157, and 3 channels at 183.31, providing a nominal horizontal resolution at nadir of approximately 16 kilometers. However, the footprint size increases significantly at the edges of the scan swath, reaching resolutions between 50 and 150 kilometers depending on scan angle.

=== Space Environment Monitor (SEM-2) ===
The SEM-2 on the Advanced TIROS-N (ATN) NOAA K-N series of polar orbiting meteorological satellites provides measurements to determine the population of the Earth's radiation belts and data on charged particle precipitation in the upper atmosphere as a result of solar activity. The SEM-2 consists of two separate sensors the Total Energy Detector (TED) and the Medium Energy Proton/Electron Detector (MEPED). In addition, the SEM-2 includes a common Data Processing Unit (DPU). The TED uses eight programmed swept electrostatic curved-plate analyzers to select particle type and energy and Channeltron detectors to measure the instensity in the selected energy bands. The particle energies range from 50 eV to 20 keV. The MEPED detects protons, electrons, and ions with energies from 30 keV to several tens of MeV. The MEPED consists of four directional solid-state detector telescopes and four omnidirectional sensors. The DPU sorts and counts the events and the results are multiplexed and incorporated into the satellite telemetry system. Once received on the ground, the SEM-2 data is separated from the rest of the data and sent to the NOAA Space Environment Laboratory in Boulder, Colorado, for processing and dissemination.

=== Solar Backscatter Ultraviolet Radiometer (SBUV/2) ===
[[https://en.wikipedia.org/wiki/File:SBUV_Instrament.jpg|thumb|An image of the SBUV instrament]]
The SBUV/2 on the Advanced TIROS-N (ATN) NOAA K-N series of polar orbiting meteorological satellites is a dual monochromator ultraviolet grating spectrometer for stratospheric ozone measurements. The SBUV/2 is designed to measure scene radiance and solar spectral irradiance in the ultraviolet spectral range from 160 to 406 nm. Measurements are made in discrete mode or sweep mode. In discrete mode, measurements are made in 12 spectral bands from which the total ozone and vertical distribution of ozone are derived. In the sweep mode, a continuous spectral scan from 160 to 406 nm is made primarily for computation of ultraviolet solar spectral irradiance. The 12 spectral channels are (nm): 252.0, 273.61, 283.1, 287.7, 292,29, 297.59, 301.97, 305.87, 312.57, 317.56, 331.26, and 339.89.

=== Search and Rescue Satellite Aided Tracking System (SARSAT) ===
The SARSAT on the Advanced TIROS-N NOAA K-N series of polar orbiting meteorological satellites is designed to detect and locate Emergency Locator Transmitters (ELTs) and Emergency Position-Indicating Radio Beacons (EPIRB). The SARSAT instrumentation consists of two elements: the Search and Rescue Repeater (SARR) and the Search and Rescue Processor (SARP-2). The SARR is a radiofrequency (RF) system that accepts signals from emergency ground transmitters at three very high frequency (VHF/UHF) ranges (121.5 MHz, 243 MHz and 406.05 MHz) and translates, multiplexes, and transmits these signals at L-band frequency (1.544 GHz) to local Search and Rescue stations (LUTs or Local User Terminals) on the ground. The location of the transmitter is determined by retrieving the Doppler information in the relayed signal at the LUT. The SARP-2 is a receiver and processor that accepts digital data from emergency ground transmitters at UHF and demodulates, processes, stores, and relays the data to the SARR where they are combined with the three SARR signals and transmitted via L-band frequency to local stations.

=== ARGOS Data Collection System (DCS-2 - Argos) ===
The DCS-2 on the Advanced TIROS-N (ATN) NOAA K-N series of polar orbiting meteorological satellites is a random-access system for the collection of meteorological data from in situ platforms (moveable and fixed). The ARGOS DCS-2 collects telemetry data using a one-way RF link from data collection platforms (such as buoys, free-floating balloons and remote weather stations) and processes the inputs for on-board storage and later transmission from the spacecraft. For free-floating platforms, the DCS-2 system determines the position to within 5 to 8 km RMS and velocity to an accuracy of 1.0 to 1.6 mps RMS. The DCS-2 measures the in-coming signal frequency and time. The formatted data are stored on the satellite for transmission to NOAA stations. The DCS-2 data is stripped from the GAC data by NOAA/NESDIS and sent to the Argos center at CNES in France for processing, distribution to users, and archival.

== Telecommunications ==
The TIP formats low bit rate instruments and telemetry to tape recorders and direct read-out. The MIRP process high data rate AVHRR to tape recorders (GAC) and direct read-out (HRPT and LAC). On-board recorders can store 110 minutes of GAC, 10 minutes HRPT and 250 minutes TIP.

== Mission ==
The Automatic Picture Transmission (APT) transmission frequency is 137.62 MHz. Due to problems with the S-band transmitter high-gain antennas, NOAA-15 has been configured for High-Resolution Picture Transmission (HRPT) using the S-Band Transmitter #2 (1702.5 MHz) omnidirectional antenna. Issues with antennas were attributed to thermal stress causing internal component breakage.

=== Failure of the AVHRR scanning motor ===
On 22 July 2019, NOAA-15 began transmitting corrupt data. The cause appears to be instability of the scanning motor for the AVHRR sensor. According to an official release from NOAA, on 23 July 2019 at 04:00 UTC, the current draw of that motor spiked, as did the motor temperature. Additionally, the sensor stopped producing data. NOAA says this is consistent with a motor stall, and could be permanent. On 25 July 2019, the AVHRR motor spontaneously recovered. On 30 July 2019, the AVHRR motor suffered another failure consistent with motor stall. As per the previous statement by NOAA, recovery is unlikely:<blockquote>As of ~00:00 UTC on 30 July 2019 (Day of year (DOY) 211), the AVHRR motor current has once again started spiking, becoming saturated above 302 mA at ~06:00 UTC. The instrument is once again no longer producing data and may be stalled. The current plan is to leave the instrument powered as this issue may be intermittent.</blockquote>The AVHRR was operating nominally and producing quality data until 18 October 2022, when again there was an issue with the AVHRR Scan Motor.<blockquote>The NOAA-15 AVHRR Scan Motor current began showing signs of instability on Oct 18 at approximately 1800Z, when the current began to gradually rise from about 205 mA to about 250 mA, where it remained until Oct 24. At about 0000Z on Oct 24, the current began rising again throughout the day, peaking at about 302mA on Oct 25. Scan motor temperature began rising about the same time and is currently steady at ~29°C. The instrument is still producing data, but it is highly degraded. This behavior may be a sign of an impending scan motor stall, but requires further investigation. Options for recovery are limited.</blockquote>The AVHRR was successfully recovered and continued operations as before until decommissioning.

== End of Mission ==
In April 2025, NOAA announced that they would suspend POES data - data from NOAA-15 and NOAA-19 - on June 16, 2025, and decommission NOAA-15 on August 12, 2025.

However, on August 9 NOAA-19 encountered a battery failure and was decommissioned early on August 13. As a result, the decommissioning date of NOAA-15 was extended until the week of August 18. NOAA will not deorbit the satellite. Instead, it has been left in orbit and put into a safe electrical state, with the transmitters shut down. NOAA-15 was ultimately decommissioned on August 19, 2025, on at 20:37 UTC.

'''Automatic Picture Transmission (APT)''', also known as '''NOAA-GEOSAT''', is an analog image transmission mode used to by the NOAA weather satellites and formerly some Russian weather satellites to transmit satellite weather photos. On August 19th 2025, the final satellite transmitting this mode (NOAA-15) was decommissioned at 15:26 UTC. This mode is no longer in use in real life, however NOAA-15 is still transmitting APT in SimTX

== Characteristics ==

=== Structure ===
The broadcast transmission was composed of two image channels, telemetry information, and synchronization data, with the image channels typically referred to as Video A and Video B. All this data was transmitted as a horizontal scan line. A complete line is 2080 pixels long, with each image using 909 pixels and the remainder going to the telemetry and synchronization. Lines were then transmitted at 2 per second, which equates to a 4160 words per second, or 4160 baud.
Format of Automatic Picture Transmission. We see the two parallel Video streams being transmitted, each at 120 LPM.

On NOAA POES system satellites, the two images are 4 km / pixel smoothed 8-bit images derived from two channels of the advanced very-high-resolution radiometer (AVHRR) sensor. The images are corrected for nearly constant geometric resolution prior to being broadcast; as such, the images are free of distortion caused by the curvature of the Earth.

Of the two images, one is typically long-wave infrared (10.8 micrometers) with the second switching between near-visible (0.86 micrometers) and mid-wave infrared (3.75 micrometers) depending on whether the ground is illuminated by sunlight. However, NOAA can configure the satellite to transmit any two of the AVHRR's image channels.

=== Synchronization and telemetry ===
Included in the transmission are a series of synchronization pulses, minute markers, and telemetry information.

The synchronization information, transmitted at the start of each video channel, allows the receiving software to align its sampling with the baud rate of the signal, which can vary slightly over time. The minute markers are four lines of alternating black then white lines which repeat every 60 seconds (120 lines).

The telemetry section is composed of sixteen blocks, each 8 lines long, which are used as reference values to decode the image channels. The first eight blocks, called "wedges," begin at 1/8 max intensity and successively increase by 1/8 to full intensity in the eighth wedge, with the ninth being zero intensity. Blocks ten through fifteen each encode a calibration value for the sensor. The sixteenth block identifies which sensor channel was used for the preceding image channel by matching the intensity of one of the wedges one through six. Video channel A typically matches either wedge two or three, channel B matches wedge four.

The first fourteen blocks should be identical for both channels. The sixteen telemetry blocks repeat every 128 lines, and these 128 lines are referred to as a frame.

=== Broadcast signal ===
The signal itself is a 256-level amplitude modulated 2400Hz subcarrier, which is then frequency modulated onto the 137 MHz-band RF carrier. Maximum subcarrier modulation is 87% (±5%), and overall RF bandwidth is 34 kHz. On NOAA POES vehicles, the signal is broadcast at approximately 37dBm (5 watts) effective radiated power.

== Frequencies ==
NOAA 15 - 137.620 MHz

== Antennas ==
The NOAA satellites that downlink APT signals transmit with a right-hand circularly polarized (RHCP) quadrifilar helical antenna (QFH). Using an RHCP QFH to receive these signals is a good idea, as the polarization will be the same and the antenna has a very wide beamwidth. Other popular choices that are circularly polarized are the turnstile and double cross dipole antenna.

Another option is a v-dipole. Though it is linearly polarized, the polarization mismatch loss is typically insignificant and easily ignored. This antenna uses two legs roughly 54cm long spread 120° apart at the feed point. This forms a 'V' shape, with the feed point (where the coaxial cable connects) at the bottom corner where both legs meet. This v-dipole is more directional than the previously mentioned antennas so it must be positioned properly. Point the antenna so that the legs are parallel to the ground, and a line bisecting the angle between the legs points North or South, it doesn't matter which. The height above the ground matters for this antenna. Heights that are multiples of half the wavelength should be avoided, so ~1m, ~2m, ~3m, etc due to nulls directly overhead. The best height is somewhere between 0.4m and 0.8m, anything higher will introduce nulls and dips in the radiation pattern. If the antenna needs to be placed higher, say above a tree line or buildings, then a reflector may be placed 0.4-0.8m below it for the same benefit. A reflector can be as simple as another v-dipole with slightly longer legs.

Permanent ground stations may wish to opt for the QFH or turnstile so that lower-elevation passes can be received. For single-pass captures or for mobile ground stations, v-dipoles are very good options as they are portable and offer more gain on high elevation passes.

	Most satellites use chemical or ion propulsion to adjust or maintain their orbit, coupled with reaction wheels to control their three axis of rotation or attitude. Satellites close to Earth are affected the most by variations in the Earth's magnetic, gravitational field and the Sun's radiation pressure; satellites that are further away are affected more by other bodies' gravitational field by the Moon and the Sun. Satellites utilize ultra-white reflective coatings to prevent damage from UV radiation. Without orbit and orientation control, satellites in orbit will not be able to communicate with ground stations on the Earth.

Without orbit and orientation control, satellites in orbit will not be able to communicate with ground stations on the Earth.

	Chemical thrusters on satellites usually use monopropellant (one-part) or bipropellant (two-parts) that are hypergolic. Hypergolic means able to combust spontaneously when in contact with each other or to a catalyst. The most commonly used propellant mixtures on satellites are hydrazine-based monopropellants or monomethylhydrazine–dinitrogen tetroxide bipropellants. Ion thrusters on satellites usually are Hall-effect thrusters, which generate thrust by accelerating positive ions through a negatively-charged grid. Ion propulsion is more efficient propellant-wise than chemical propulsion but its thrust is very small ~~(around {{Cvt\|0.5\|N\|disp=or\|sigfig=1}})~~, and thus requires a longer burn time. The thrusters usually use xenon because it is inert, can be easily ionized, has a high atomic mass and storable as a high-pressure liquid.

For testing purposes, satellites in low earth orbit have been destroyed by ballistic missiles launched from the Earth. Russia, United States, China and India have demonstrated the ability to eliminate satellites. In 2007, the Chinese military shot down an aging weather satellite, followed by the US Navy shooting down a defunct spy satellite in February 2008. On 18 November 2015, after two failed attempts, Russia successfully carried out a flight test of an anti-satellite missile known as ''Nudol''.
