Detailed Description

Class for reading/writing attitude generic files.

Constructor & Destructor Documentation

EECFI.AttFile.AttFile ( )

Empty constructor.

EECFI.AttFile::AttFile ( final String fileNam )

Constructor with file name.

Parameters:

fileNam

Name of the file.

Member Function Documentation

native AttFile EECFI.AttFile.decimate ( double decimationDeltaTime ) throws CfiError

Decimate the list of attitude records according to input delta time.

Being t0 the time of the 1st attitude record of input list (calling object) and D the decimationDeltaTime, the attitude records from the input list that will be included in the output list will be those closer to every time t=t0+k*D (k=1,2...n). Important: the fixed header of calling object must have been read.

native void EECFI.AttFile.read ( ) throws CfiError

Read the whole data block and store it in object.

void EECFI.AttFile::write	(	String	fileNam,
		FixedHeader	fixedHead,
		Vector< AttRec >	attRecords,
		final long	srcRef,
		final long	datTyp,
		final double	maximumGap,
		final long	satReference
	)			throws CfiError

Write attitude file with a new name.

Note about output format: the number of decimal digits written to file depends on the type of data:

If angles are used, 6 decimal digits are written.
If quaternions are used, 9 decimal digits are written.

It is done this way because having 9 decimal digits in quaternions reduces pointing error significantly .

Parameters:

	fileNam	New file name.
	fixedHead	Values of the fixed header.
	attRecords	Vector of attitude data.
	srcRef	Initial reference frame.
	datTyp	Angles of quaternions (AttitudeDataTypeEnum).
	maximumGap	Maximum time gap between two cosecutive records.
	satReference	Target reference frame.

void EECFI.AttFile::write	(	FixedHeader	fixedHead,
		Vector< AttRec >	attRecords,
		final long	srcRef,
		final long	datTyp,
		final double	maximumGap,
		final long	satReference
	)			throws CfiError

Write attitude file with name given in constructor.

Note about output format: the number of decimal digits written to file depends on the type of data:

If angles are used, 6 decimal digits are written.
If quaternions are used, 9 decimal digits are written.

It is done this way because having 9 decimal digits in quaternions reduces pointing error significantly .

Parameters:

	fixedHead	Values of the fixed header.
	attRecords	Vector of attitude data.
	srcRef	Initial reference frame.
	datTyp	Angles of quaternions (AttitudeDataTypeEnum).
	maximumGap	Maximum time gap between two cosecutive records.
	satReference	Target reference frame.
