Remarks: (1) AS on this week.
(2) Hardware problem at Vandenberg resulting in large vertical
repeatability.
(3) This week, we incorporated a distributed processing scheme for
the PGGA and IGS analysis. This consists of two separate GAMIT
solutions. In the first solution, IGS stations are processed
in common with only the Goldstone PGGA station. In the second
solutions, all PGGA stations are processed (including Goldstone)
with the IGS sites: Algonquin, Kokee Park, Richmond and Penticton.
Thus, there are five common stations in each pair of solutions.
The solution file (h-file) output of each solution are input to
GLOBK to produce station positions, satellite orbits and polar
motion. That is, we now have 14 GAMIT solution files per week rather
than 7 solution files that we generated with the simultaneous
IGS/PGGA solutions. This approach is much more efficient since
the total number of stations in the larger IGS solution is about
28 as compared to a total of 36 stations in the simultaneous
approach. The quality of the global products and station positions
generated by the distributed approach are not significantly degraded
in precision.
(4) The North Liberty site has been added to the PGGA solution.
