(2) PRN03 has been malfunctioning recently and failed on day 077 (3) PRN25 was unusable from day 076 15:00 to day 077 04:00 (4) Hardware problem at Vandenberg resulting in large vertical repeatability. (5) 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. (6) The North Liberty site has been added to the PGGA solution.
