Subject: Another SINEX format
After examining the mail messages from Jeff Freymuller (#816) and
Michael Heflin (#844), and looking over the GLOBK h-file format
developed by Tom Herring, I've come up with another attempt at the
SINEX format. As you can see below, it is modeled after the RINEX format.
This format can be generalized to all types of space geodetic solutions
(e.g., VLBI, SLR) so the first line indicates that this one is for GPS.
The second line refers to a non-existent SINEX0 program, which
will translate a particular software's solution format to SINEX.
The COMMENT lines and the next three lines are straightforward.
Then I've categorized information according to headers. The
first header line provides the format for the corresponding lines
for each category. The ###'s indicate the extent of that field.
There are TIME, SITE ID, SITE INFO, ANTENNA OFFSETS, SITE
COORDINATES, OBSERVATIONS, SATELLITE INFO & ADJUSMENT headers,
followed by END OF HEADER .
Next comes the PARAMETER ADJUSTMENTS. This format comes from a GAMIT
output file with the units as shown. This part of the proposed
format is the least well developed.
Next comes the COVARIANCE MATRIX ordered by row number, in lower
triangular form in D-format. This is more compact than the other
formats proposed and is in fact GLOBK format.
Note that I have only included station coordinates and earth orientation
parameters, although in GAMIT/GLOBK we also include satellite parameters.
Also, the information given in the example below is fictitious.
Let me know what you think.
