The attitude information is input in the form of an attidude state vector which consists of a:
This information is provided to the LAT from the SC GNC system. The attitude library maintains a short time history of the attitude information to allow for vector transformations at arbitrary times in the recent past. Call the function ATT_update() to inform the attitude processing software of a new message available from the SC.
