Nav System
Differential GPS with a final post-cruise UKOOA 90 P1 navigation format (EW9907.v19.ukooa; 932 MB uncompressed; 290 MB compressed). This format includes all the important data associated with the navigation systems; antennas positions; cable compasses and positions for each source of the approximately 150;000 shots and each of the 240 channels. In addition there is the 'standard' *.nav file of just shot locations for the cruise and by line.
