GSSC Now, explore more than 100 million GNSS assets


More than 100 million GNSS public assets available in our GNSS Science Exploitation Platform, GSSC Now, a facility of ESA’s Navigation Science Office. This represents another step forward since March 2022, when our first public beta unveiled ESA’s innovative proposal for collaboration, exploration, and analysis to accelerate science unleashing the full potential of ESA GNSS archives.  

GSSC Now indexed datasets include CORS assets (CDDIS, BKG or IGN), ESA missions such as SWARM, GREAT, GOCE, GNSS experiments and many more! 

Boost your GNSS research with a two steps approach. First, explore assets with advanced filtering capabilities on, observation codes, stations, instruments, sampling rates, observed satellites, and dates, among others. Second, run on-demand scientific tools, called datalabs, to generate insights from previous selection.

GSSC Now repository is continuously growing and many more datasets and datalabs – with demonstrators and unique functionalities for the treatment of the available data/products – will be made available to the scientific community in the near future.
