Member Function Documentation

void EECFI::AttitudeDef::attitudeTransform ( TransformCfg & transformCfg ) throw (CfiError)

The reference frame in the attitude id can be changed using attitudeTransform.

Remark: all attitude related computations are performed in the True of Date Coordinate System. This means that, if one attitude id has been initialized with data expressed in another reference frame (e.g. attitude file with quaternions expressed in EF), at each call of a function using such attitude id (e.g. Attitude::compute) one or more conversions to True of Date will be performed. If the reference frame is changed to True of Date (using AttitudeDef::attitudeTransform), such conversions will not be executed and this will result in a run-time performance improvement.
Note: transformation of attitude ids that are initialized with Start Tracker files is not supported.

Parameters:

transformCfg

Transformation parameters.

AttFile EECFI::AttitudeDef::genAttitudeData	(	OrbitId &	orbId,
		const OrbTimeInterval &	timeInterval,
		double	timeStep,
		long	dataType,
		long	sourceRefType,
		long	sourceRef
	)			const throw (CfiError)

Compute a list of quaternions/angles equivalent to the transformation from sourceRef to the attitude target frame.

A data set (quaternions/angles) is generated every "timeStep" seconds along the input "timeInterval"

Parameters:

	timeInterval	Time interval to be generated
	timeStep	interval between records in file (seconds)
	dataType	Euler angles or quaternions
	sourceRefType	source reference frame type (External or satellite)
	sourceRef	source reference frame

Returns:: AttFile object with the list of quaternions or angles.

		long	sourceRef,
		string	outputDir,
		string	fileClass,
		long	versionNumber,
		string	fhSystem,
		string &	outputFileName
	)			const throw (CfiError)

Create an attitude file with quaternions/angles equivalent to the transformation from sourceRef to the attitude target frame.

The file records are generated every "timeStep" seconds along the input "timeInterval"

Parameters:

	OrbitId	Orbit Id.
	timeInterval	Time interval to be generated
	timeStep	interval between records in file (seconds)
	dataType	Euler angles or quaternions
	sourceRefType	source reference frame type (External or satellite)
	sourceRef	source reference frame
	outputDir	output directory
	fileClass	file calss
	versionNumber	file version
	fhSystem	FH system
	outputFileName	Output file name. If emtpy is generated automatically
