Detailed Description

Defines the class that provides the ability to convert GLONASS to/from UT1 (UTC Greenwich, to distinguish it from UTC(SU)), using data extracted from GLONASS navigation messages. The algorithm is sufficiently different from what's in StdNavTimeOffset (in that the time difference is between the ephemeris and almanac times rather than some reference time and the desired time) that it's implemented apart from StdNavTimeOffset.

void gnsstk::GLOFNavUT1TimeOffset::dump	(	std::ostream &	s,
		DumpDetail	dl
	)		const

overridevirtual

Print the contents of this object in a human-readable format.

Parameters

[in,out]	s	The stream to write the data to.
[in]	dl	The level of detail the output should contain.

Reimplemented from gnsstk::NavData.

Definition at line 59 of file GLOFNavUT1TimeOffset.cpp.

◆ dumpTerse()

void gnsstk::GLOFNavUT1TimeOffset::dumpTerse ( std::ostream & s ) const

Parameters

[in,out] s The stream to write the data to.

Definition at line 129 of file GLOFNavUT1TimeOffset.cpp.

◆ getConversions()

TimeCvtSet gnsstk::GLOFNavUT1TimeOffset::getConversions ( ) const

overridevirtual

The set of time system conversions this class is capable of making.

Returns: a set of supported time system conversion to/from pairs.

Implements gnsstk::TimeOffsetData.

Definition at line 172 of file GLOFNavUT1TimeOffset.cpp.

◆ getOffset()

bool gnsstk::GLOFNavUT1TimeOffset::getOffset	(	TimeSystem	fromSys,
		TimeSystem	toSys,
		const CommonTime &	when,
		double &	offset
	)		const

overridevirtual

Get the offset, in seconds, to apply to times when converting them from fromSys to toSys.

Parameters

[in]	fromSys	The time system to convert from.
[in]	toSys	The time system to convert to.
[in]	when	The time being converted, in the same time system as fromSys.
[out]	offset	The offset in seconds where when(toSys)=when(fromSys)-offset.

Exceptions

AssertionFailure if when's time system is not fromSys.

Returns: true if an offset is available, false if not.

Implements gnsstk::TimeOffsetData.

Definition at line 149 of file GLOFNavUT1TimeOffset.cpp.

◆ validate()

bool gnsstk::GLOFNavUT1TimeOffset::validate ( ) const
