TSPI DATA REDUCTION: TIME, SPACE, AND POSITION INFORMATION DATA (V0.7.18) (15-JAN-2003)

TSPI DATA REDUCTION: TIME, SPACE, AND POSITION INFORMATION DATA (V0.7.18) (15-JAN-2003)., Flight testing of aircraft, and the accuracy of airborne sensors requires a source of truth data which can be compared against the on-board data. This Time Space and Position Information (TSPI) data needs to be post-processed and merged with the aircraft data. This paper describes some of the issues and techniques used to perform this data merging. In particular, details of the coordinate transfer from the TSPI reference point to the aircraft is discussed, along with the format of various TSPI files.
