Detailed Description

Sat position and velocity predictions over TEME reference system.

Class to abstract all the SGP4 complexity. It implementation wrap whit an object oriented class the revised David. A. Vallado code for SGP4 Calculation. (Spacetrack report #6 revised AIAA-2006-6753-rev1)

Member Function Documentation

gVector gSatTEME::getPos ( )

inline

Get the TEME satellite position Vector.

Returns

gVector Satellite position vector meassured in Km. x: position[0] y: position[1] z: position[2]

Definition at line 93 of file gSatTEME.hpp.

gVector gSatTEME::getSubPoint ( )

inline

Get the Geographic satellite subpoint Vector calculated by the method compute SubPoint.

To implement this operation, next references has been used: Orbital Coordinate Systems, Part III By Dr. T.S. Kelso http://www.celestrak.com/columns/v02n03/

Returns

gVector Geographical coordinates
Latitude: Coord[0] measured in degrees
