Satellite data, GNSS
We are developing automatic double difference processing of GNSS data for the ground motion and strain analysis. This is a massive processing using the suite of programs GAMIT-GLOBK developed by Massachusetts Institute of Technology, Scripps Institution of Oceanography and Harvard University.
In particular, we are working on GNSS data processing for the EPOS (European Plate Observing System) project, where a large amount of data requires adapting the processing chain. As part of this project, we provide EPOS-GNSS products (daily solutions, time series positions and velocity fields).
