Satellite Positions


Satellite positions can be expressed in various coordinate systems. WinOrbit uses the following positions:
* Latitude/Longitude/Altitude
* Inertial (Celestial) Cartesian system
* Geodetic Cartesian system.
The state vector published by NASA for Shuttle operations is an Earth-fixed Greenwich, or Geodetic position. The NASA state vector E, F, and G values (in feet) can be obtained from the WinOrbit Geodetic position by multiplying by 3280.839895 feet/km.
