GENESIS (Global Environmental & Earth Science Information System) is a suite of data services that bring together the Earth science products generated by spaceborne Global Positioning System (GPS) receivers flying on several international missions. GENESIS provides a database for GPS occultation observations from various spacecraft carrying NASA-supplied GPS receivers designed for atmospheric and ionospheric sounding. The flight database is augmented with GPS ground data and a variety of higher level derived products.
The missions that are carrying RO instruments include:
