! Control !! Meaning
|-
| '''Circular''', '''Elliptical''' || One altitude, or a '''Lowest point''' and '''Highest point''' with the highest point over the '''North''' or '''South'''.
|-
| '''Altitude''' || 200 to 40,000 km. Higher orbits are slower, see more of the Earth and stay in view longer, but the signal is weaker.
|-
| '''Inclination''' || The tilt against the equator: 0° stays over the equator, 90° crosses the poles, above 90° runs against the Earth's rotation. The track reaches north and south to the latitude of the inclination. Sun-synchronous sets it for you.
|-
| '''Parked over longitude''' || Geostationary: where the satellite stays. From a given place it is always in view or never.
|-
| '''Highest point over longitude''' || Molniya: where its high point hangs.
|-
| '''Starting point''' || Where the first orbit begins, '''Northbound''' or '''Southbound'''. '''Pick on globe''' or '''Over my station…''' places it.
|-
| '''Orbital elements''' || The orbit as numbers, for typing exact values. '''Back to guided controls''' returns to the controls.

Beside the form, '''Orbit takes''', '''Speed''', '''Footprint radius''', '''Max Doppler''', '''Coverage''' and the passes per day over each of your ground stations update as you design. A warning appears if the orbit can't be flown.
