Detailed Description

Factory class for loading SEM nav data.

Note: While in theory Y code and P code LNav are supported, SEM nav does not support the identification of the codes contained in the files. As such, this factory only "produces" L1 C/A tagged data for LNav.

Constructor & Destructor Documentation

◆ SEMNavDataFactory()

gnsstk::SEMNavDataFactory::SEMNavDataFactory ( )

Fill supportedSignals.

Note: Only GPS nav is supported so only that will be added to supportedSignals.

Definition at line 51 of file SEMNavDataFactory.cpp.

◆ ~SEMNavDataFactory()

virtual gnsstk::SEMNavDataFactory::~SEMNavDataFactory ( )

inlinevirtual

Clean up.

Definition at line 64 of file SEMNavDataFactory.hpp.

Member Function Documentation

◆ convertToHealth()

bool gnsstk::SEMNavDataFactory::convertToHealth	(	const SEMData &	navIn,
		NavDataPtr &	healthOut
	)

static

Convert SEM nav data to a system/code-appropriate NavHealthData object.

Parameters

[in]	navIn	The SEM nav message data to convert.
[out]	healthOut	The NavHealthData object to be added to the factory data map.

Returns: true if the conversion is valid, false if the input data is unsupported.

Definition at line 243 of file SEMNavDataFactory.cpp.

◆ convertToOrbit()

bool gnsstk::SEMNavDataFactory::convertToOrbit	(	const SEMData &	navIn,
		NavDataPtr &	navOut
	)

static

Convert SEM nav data to a system/code-appropriate OrbitData object.

Parameters

[in]	navIn	The SEM nav message data to convert.
[out]	navOut	The OrbitData object to be added to the factory data map.

Returns: true if the conversion is valid, false if the input data is unsupported.

Definition at line 192 of file SEMNavDataFactory.cpp.

◆ fillNavData()

void gnsstk::SEMNavDataFactory::fillNavData	(	const SEMData &	navIn,
		NavDataPtr &	navOut
	)

static

Fill the high level (NavData and above) data for an object using information from a SEM nav record.

Parameters

[in]	navIn	The SEM nav message data to convert.
[in,out]	navOut	A NavDataPtr that has already been allocated for the appropriate leaf node class (e.g. GPSLNavEph, GPSLNavHealth, etc.)

Postcondition: If navIn contains valid, supported data, the timeStamp and signal data members will be filled in.

Definition at line 260 of file SEMNavDataFactory.cpp.

◆ getFactoryFormats()

std::string gnsstk::SEMNavDataFactory::getFactoryFormats ( ) const

overridevirtual

Return a comma-separated list of formats supported by this factory.

Implements gnsstk::NavDataFactory.

Definition at line 179 of file SEMNavDataFactory.cpp.

◆ loadIntoMap()

bool gnsstk::SEMNavDataFactory::loadIntoMap	(	const std::string &	filename,
		NavMessageMap &	navMap,
		NavNearMessageMap &	navNearMap,
		OffsetCvtMap &	ofsMap
	)

overridevirtual

Load SEM nav data into a map.

Parameters

[in]	filename	The path of the file to load.
[out]	navMap	The map to store the loaded data in.
[out]	navNearMap	The map to store the loaded data in for use by "Nearest" (as opposed to "User") searches.
[out]	ofsMap	The map to load TimeOffsetData into.

Returns: true on succes, false on failure.

Implements gnsstk::NavDataFactoryWithStoreFile.

Definition at line 61 of file SEMNavDataFactory.cpp.

◆ process()

bool gnsstk::SEMNavDataFactory::process	(	const std::string &	filename,
		NavDataFactoryCallback &	cb
	)

overridevirtual

Process the data in the specified file using a custom callback. Each message decoded by the factory class will be run through NavDataFactoryCallback::process(). It is expected that the user will derive a class from NavDataFactoryCallback, implement the details of the process method to suit their use case, and apply it here.

Parameters

[in]	filename	The path of the file to process.
[in]	cb	The call back to use to process the data in the file.

Returns: true on success, false on failure.

Implements gnsstk::NavDataFactoryWithStoreFile.
