08/22/88 EDM DRS$DATA:[F587SC.N]F587SC.050;
DUA0:[DATA.][F587SC.N]TEMP.EXE;
Integrated navigation (SINS) data
Program TEMP was written to eliminate contiguous records with equal lat/longs.

02/04/88 EDM DRS$DATA:[F587SC]F587SCNEWER.050;
DUA0:[DATA.][F587SC]COMBINE2.EXE;
Combination of (in order of preference): GPS from tape, GPS from Sonotrak,

G = GPS from tape, A = GPS from Sonotrak, R = RHO-RHO from tape, B = RHO-RHO
Sonotrak, F = IBM floppy.
The program COMBINE2 was written to combine navigation files from different
sources for the same cruise. It uses the first file given over the second file,
and uses the second file to fill in gaps in the first file. Only gaps greater
than or equal to 15 minutes are filled, starting 2 minutes into the gap and
ending 2 minutes before the end of the gap. In addition, a one-letter code is
appended to the end of each record to indicate what the source of that record
was. This code is user defined, and should be documented in the file header at
the time the program is executed.
