Figure 11.1: The FGS POS TARG and interferometer coordinate systems.
The POS TARG reference frame must be used to specify Special Requirements POS TARG and ORIENTation. Note that the FGS interferometer axes and POS TARG axes have different origins and parities. The interferometer reference frame is used in pipeline processing only.
