◆ ComputeAtTransmitTime() [1/2]

double gnsstk::PreciseRange::ComputeAtTransmitTime	(	const CommonTime &	nomRecTime,
		const double	pr,
		const Position &	rxPos,
		const SatID	sat,
		const AntexData &	antenna,
		const std::string &	freq1,
		const std::string &	freq2,
		SolarSystem &	solSys,
		NavLibrary &	eph,
		bool	isCOM = `false`,
		const EllipsoidModel &	ellipsoid = `GPSEllipsoid()`
	)

Compute the corrected range at transmit time from ephemeris is the given NavLibrary, from receiver at position Rx with measured pseudorange pr and time tag nomRecTime, to the GPS satellite given by SatID sat, as well as all the CER quantities.

Parameters

nomRecTime	nominal receive time
pr	measured pseudorange at this time
rxPos	receiver position
sat	satellite
antenna	satellite antenna data;
freq1,freq2	ANTEX frequencies to evaluate PCO/Vs eg 'G01' if freq2 is zero e.g. 'G00', compute single freq (freq1) PCO/Vs
solSys	SolarSystem object, to get SatelliteAttitude() if any of above 4 not valid, PCO/V correction is NOT done (silently)
eph	Ephemeris store
isCOM	if true, Eph is Center-of-mass, else antenna-phase-center, default false.
ellipsoid	Ellipsoid model to provide an ECEF rotation rate.

Returns: corrected raw range

Exceptions

Exception if ephemeris is not found
