SPOTGINS is a distributed analysis center where multiple research groups cooperate by using the same software, the same processing strategy, and the same metadata to produce a common set of GNSS time series.

We use the GINS software, developed by CNES, and the precise GPS & Galileo orbit/clock products of the CNES-CLS IGS Analysis Center.

We produce daily PPP position time series and hourly zenith tropospheric delay time series from globally accessible GNSS observations. The SPOTGINS position time series are available on The Geodesy Plotter of the Solid Earth Center portal (ForM@Ter).
