Public Member Functions | |
AttFile () | |
Empty constructor. | |
AttFile (final String fileNam) | |
Constructor with file name. | |
native void | read () throws CfiError |
Read the whole data block and store it in object. | |
native void | 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. | |
native void | 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. | |
native AttFile | decimate (double decimationDeltaTime) throws CfiError |
Decimate the list of attitude records according to input delta time. | |
Public Attributes | |
Vector< AttRec > | attRec |
Vector of attitude data. | |
long | sourceRef |
Initial reference frame: inertial reference frame. | |
long | dataType |
Angles or quaternions (AttitudeDataTypeEnum). | |
double | maxGap |
Maximum time gap between two consecutive records. | |
long | satRef |
Target reference frame. |
Class for reading/writing attitude generic files.
EECFI.AttFile.AttFile | ( | ) |
Empty constructor.
EECFI.AttFile::AttFile | ( | final String | fileNam | ) |
Constructor with file name.
fileNam | Name of the file. |
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 | ( | FixedHeader | fixedHead, | |

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

FixedHeader | fixedHead, | |||
Vector< AttRec > | attRecords, | |||
final long | srcRef, | |||
final long | datTyp, | |||

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:
It is done this way because having 9 decimal digits in quaternions reduces pointing error significantly .
fileNam | New file name. | |
fixedHead | Values of the fixed header. | |
attRecords | Vector of attitude data. | |

Vector of attitude data.
Angles or quaternions (AttitudeDataTypeEnum).
double EECFI.AttFile.maxGap |
Maximum time gap between two consecutive records.
long EECFI.AttFile.satRef |
Target reference frame.
Initial reference frame: inertial reference frame.
