The Space to Ground (S2G) Data Viewer is an extensible software application that allows you to easily inspect the contents of CCSDS-compliant telemetry data exchanged between a satellite and its ground segments on the space-to-ground link.
Support for Copernicus Sentinel missions as well as for the Earth Explorers (Aeolus, Swarm, SMOS, SeoSAT and EarthCARE) and MetOp-SG-A/B and Meteosat Third Generation is already built-in and the S2G configuration can be extended by the user to support different missions.
The application is available for Windows, Linux and Mac OS X.
