Constructor & Destructor Documentation

◆ GPSLNavAlm()

gnsstk::GPSLNavAlm::GPSLNavAlm ( )

Sets the nav message type.

Definition at line 47 of file GPSLNavAlm.cpp.

Member Function Documentation

◆ clone()

NavDataPtr gnsstk::GPSLNavAlm::clone ( ) const

inlineoverridevirtual

Create a deep copy of this object.

Implements gnsstk::NavData.

Definition at line 56 of file GPSLNavAlm.hpp.

◆ dumpHarmonics()

void gnsstk::GPSLNavAlm::dumpHarmonics ( std::ostream & s ) const

inlineoverridevirtual

Override dumpHarmonics to hide them in output since GPS LNav almanacs don't contain this data.

Reimplemented from gnsstk::OrbitDataKepler.

Definition at line 68 of file GPSLNavAlm.hpp.

◆ dumpSVStatus()

void gnsstk::GPSLNavAlm::dumpSVStatus ( std::ostream & s ) const

overridevirtual

Dump SV status information (e.g. health).

Parameters

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

Reimplemented from gnsstk::OrbitDataKepler.

Definition at line 75 of file GPSLNavAlm.cpp.

◆ fixFit()

void gnsstk::GPSLNavAlm::fixFit ( )

Fill the beginFit and endFit values for this object.

Definition at line 65 of file GPSLNavAlm.cpp.

◆ validate()

bool gnsstk::GPSLNavAlm::validate ( ) const

overridevirtual

Checks the contents of this message against known validity rules as defined in the appropriate ICD.

Todo:: implement some checking.

Returns: true if this message is valid according to ICD criteria.

Implements gnsstk::NavData.

Definition at line 58 of file GPSLNavAlm.cpp.
