Description

Member Description

const char * readLine ( FILE *f )

enum

GPSEphemeris ()

default constructor

GPSEphemeris( const char *filename )

Int importIGS (const char *filename)

Loads IGS/SP3 file

Bool svnValid ( uInt svn )

do we have ephemeris for this SVN?

Bool orbSigma ( uInt svn )

returns the orbital accuracy indicator (=exponent of sigma) for SVN

const Vector<Double> & getEpochs ()

returns vector of epochs

const Matrix<Double> & getEph (uInt svn)

returns ephemeris of given SVN

Matrix<Double> splineEph (uInt svn,const Vector<Double> &mjd1 ) const

Splines the ephemeris of sattelite SVN to time grid MJD1, and returns the result as a (nep,3) matrix of ephemeris.

Vector<MVDirection> splineAzEl (uInt svn,const Vector<Double> &mjd1, const MVPosition &pos) const

Splines the ephemeris of sattelite SVN to new time grid MJD1, and returns the result as a (nep) vector of MVDirections, corresponding to Az/El from the observation point given by POS (ITRF). Tension is the spline tension, 0 for default (1e-3).
