Orbit2Groundtracks

This program write satellites positions as gridded data (outputfileTrackGriddedData) in a terrestrial reference frame. The points are expressed as ellipsoidal coordinates (longitude, latitude, height) based on a reference ellipsoid with parameters R and inverseFlattening. The orbit data are given in the celestial frame so earthRotation is needed to transform the data into the terrestrial frame. The data of inputfileInstrument are appended as values to each point.

Name	Type	Annotation
outputfileGriddedData	filename	positions as gridded data
inputfileOrbit	filename
inputfileInstrument	filename	values at grid points
earthRotation	earthRotation	transformation from CRF to TRF
R	double	reference radius for ellipsoidal coordinates
inverseFlattening	double	reference flattening for ellipsoidal coordinates
