[IGSMAIL-7005] 20 Years of GPS Time Series

[Heflin, Michael B (335N)]

Twenty years ago our GPS Time Series web page was launched at JPL.
Current results are based on free-network point positions with ambiguity resolution transformed into IGS08.

A large number of people, institutions, and nations have contributed to improvements over the years including:
Sharing of GPS data from around the world
Reprocessing orbits and clocks with consistent state of the art models
Resolving of ambiguities for individual point positions
Automating outlier removal, break detection, and weekly estimates for all parameters

The original IGS Mail announcement is included below.
