Geodetic products

Several massive GNSS data processing workflows are currently carried out at ISTerre.
We use the GAMIT/GLOBK software (double-difference processing) and the GipsyX software (PPP processing) in the framework of several European projects to generate different GNSS products (time series of positions, secular velocities, discontinuities/offsets).

Double difference processing (GAMIT-GLOBK) in the framework of EPOS-GNSS

In the framework of the European research infrastructure EPOS, the thematic service EPOS-GNSS involves eight partners in Europe and aims at archiving and disseminating GNSS (Global Navigation Satellite System) data from permanent stations all over Europe (RINEX files) and derived products (daily solutions, time series of positions, velocity fields and deformation fields). In this framework, OSUG/ISTerre hosts one of the two GNSS data processing centres.
This processing work is presented in more detail here.

Processing in PPP (GipsyX) in the framework of the ERC DEEP-trigger

In the framework of the ERC DEEP-trigger, a massive GNSS data processing for South America has been implemented.
The processed stations and some of the results obtained are presented via this interactive map.
