Remarks: (1) AS on this week.
         (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.
