◆ getSvXvt()

gnsstk::Xvt gnsstk::ord::getSvXvt	(	const gnsstk::SatID &	sat_id,
		const gnsstk::CommonTime &	time,
		NavLibrary &	ephemeris
	)

Given a satellite id, a time, and an ephemeris store, retrieves the satellite location/velocity in xvt instance. This is a relatively thin wrapper for NavLibrary.getXvt() to bring the method into the same namespace as the other range calculations.

Parameters

sat_id	Identifier for the satellite
time	The time of interest.
ephemeris	The ephemeris to query against.

Returns: Xvt instance containing satellite location/velocity

Todo:: getXvt was expected to throw an exception on failure in the past. This assert more or less mimics that behavior. Refactoring is needed.

◆ IonosphereFreeRange()

double gnsstk::ord::IonosphereFreeRange	(	const std::vector< double > &	frequencies,
		const std::vector< double > &	pseudoranges
	)

Given a set of frequency and pseudorange pairs, attempts to compensate for ionospheric effects. Vectors are used because they carry a size parameter, another collection type may be more appropriate.

Parameters

frequencies	Signal frequencies.
pseudoranges	Pseudorange values for frequencies.

Returns: Corrected pseudorange in meters

Definition at line 60 of file ord.cpp.

◆ IonosphereModelCorrection()

double gnsstk::ord::IonosphereModelCorrection	(	const gnsstk::IonoModelStore &	ionoModel,
		const gnsstk::CommonTime &	time,
		CarrierBand	band,
		const gnsstk::Position &	rxLoc,
		const gnsstk::Xvt &	svXvt
	)

Given an ionosphere model, and locations of receiver and satellite, range correction due to ionospheric effects.

Parameters

ionoModel	Class that encapsulates ionospheric models
time	The time of interest.
frequency	Frequency of interest - see note above.
rxLoc	The location of the receiver.
svXvt	The location of the satellite at time of interest.

Returns: Range correction (delta) in meters

Definition at line 94 of file ord.cpp.

◆ RawRange1()

double gnsstk::ord::RawRange1	(	const gnsstk::Position &	rx_loc,

		gnsstk::Xvt &	sv_xvt
	)

Calculate the raw range at RECEIVE time per RECEIVER clock.

Deprecated:: This function is deprecated as of the December 2022 release Use RawRange::fromReceive() instead

Parameters

rx_loc	The location of the receiver.
sat_id	Identifier for the satellite
time	The nominal receive time.
ephemeris	The ephemeris to query against.

		const gnsstk::SatID &	sat_id,
		const gnsstk::CommonTime &	time,
		NavLibrary &	ephemeris,
		gnsstk::Xvt &	sv_xvt
	)

Calculate the raw range at TRANSMIT time per the RECEIVER clock.

Deprecated:: This function is deprecated as of the December 2022 release Use RawRange::fromNominalReceiveWithObs() instead

◆ RawRange3()

double gnsstk::ord::RawRange3	(	double	pseudorange,
		const gnsstk::Position &	rx_loc,
		const gnsstk::SatID &	sat_id,
		const gnsstk::CommonTime &	time,
		NavLibrary &	ephemeris,
		gnsstk::Xvt &	sv_xvt
	)

Calculate the raw range at TRANSMIT time per the SATELLITE clock

Deprecated:: This function is deprecated as of the December 2022 release Use RawRange::fromSvTransmitWithObs() instead

See also: CorrectedEphemerisRange::ComputeAtTransmitSvTime()

Parameters

pseudorange	Pseudorange in meters to seed the calculation.
rx_loc	The location of the receiver.
sat_id	Identifier for the satellite
time	The transmit time reported by satellite.

		const gnsstk::CommonTime &	time,
		NavLibrary &	ephemeris,
		gnsstk::Xvt &	sv_xvt
	)

Calculate the raw range at TRANSMIT time per RECEIVER clock, without seeding the pseudorange.

Deprecated:: This function is deprecated as of the December 2022 release Use RawRange::fromNominalReceive() instead

See also: CorrectedEphemerisRange::ComputeAtTransmitTime(const CommonTime& trNom, const Position&, const SatID, NavLibrary&, NavSearchOrder, SVHealth, NavValidityType)

Parameters

rx_loc	The location of the receiver.
