Vec3d gSatWrapper::getAltAz ( )

This operation compute the coordinates in StelCore::FrameAltAz.

Returns
Vect3d Vector with coordinates (meassured in km)

void gSatWrapper::getSlantRange ( double &  ao_slantRange,
double &  ao_slantRangeRate 
)

This operation compute the slant range (distance between the satellite and the observer) and its variation/seg.

Parameters
&ao_slantRangeReference to a output variable where the method store the slant range measured in Km
&ao_slantRangeRateReference to a output variable where the method store the slant range variation in Km/s
Returns
void
Vec3d gSatWrapper::getSubPoint ( )

This operation isolate getSubPoint method of gSatTEME object.

Returns
Vec3d Geographical coordinates
Latitude: Coord[0] measured in degrees
Longitude: Coord[1] measured in degrees
Altitude: Coord[2] measured in Km.
Vec3d gSatWrapper::getTEMEPos ( )

This operation isolate gSatTEME getPos operation.

Returns
Vec3d with TEME position. Units measured in Km.
Vec3d gSatWrapper::getTEMEVel ( )

This operation isolate gSatTEME getVel operation.

Returns
Vec3d with TEME speed. Units measured in Km/s.
int gSatWrapper::getVisibilityPredict ( )

This operation predicts the satellite visibility contidions.

This prediction can return 4 different states RADAR_SUN when satellite an observer are in the sunlit VISIBLE when satellite is in sunlit and observer is in the dark. Satellite could be visible in the sky. RADAR_NIGHT when satellite is eclipsed by the earth shadow. NOT_VISIBLE The satellite is under the observer horizon

Returns
1 if RADAR_SUN 2 if VISIBLE 3 if RADAR_NIGHt 3 if NOT_VISIBLE
