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.
