Constructor & Destructor Documentation

◆ GalFNavAlm()

gnsstk::GalFNavAlm::GalFNavAlm ( )

Sets the nav message type.

Definition at line 50 of file GalFNavAlm.cpp.

Member Function Documentation

◆ clone()

NavDataPtr gnsstk::GalFNavAlm::clone ( ) const

inlineoverridevirtual

Create a deep copy of this object.

Implements gnsstk::NavData.

Definition at line 63 of file GalFNavAlm.hpp.

◆ dumpHarmonics()

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

inlineoverridevirtual

Override dumpHarmonics to hide them in output since Galileo F/NAV almanacs don't contain this data.

Reimplemented from gnsstk::OrbitDataKepler.

Definition at line 84 of file GalFNavAlm.hpp.

◆ dumpSVStatus()

void gnsstk::GalFNavAlm::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 115 of file GalFNavAlm.cpp.

◆ fixFit()

void gnsstk::GalFNavAlm::fixFit ( )

Fill the beginFit and endFit values for this object.

Todo:: set the fit interval correctly

Definition at line 83 of file GalFNavAlm.cpp.

◆ fixHealth()

void gnsstk::GalFNavAlm::fixHealth ( )

Set the SVHealth value "health" according to the health status variable hsE5a.

Definition at line 93 of file GalFNavAlm.cpp.

◆ getUserTime()

CommonTime gnsstk::GalFNavAlm::getUserTime ( ) const

overridevirtual

Returns the time when the navigation message would have first been available to the user equipment, i.e. the time at which the final bit of a given broadcast navigation message is received. This is used by NavDataFactoryWithStore::find() in User mode.

Returns: transmit time of most recent message type of the pair + 10s.

Reimplemented from gnsstk::NavData.

Definition at line 76 of file GalFNavAlm.cpp.

◆ validate()

bool gnsstk::GalFNavAlm::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 69 of file GalFNavAlm.cpp.
