Radio occultation

Radio occultation analysis of signal delay by the tandem FORMOSAT-3/COSMIC used as atmospheric sounding.

Radio occultation (RO) is a remote sensing technique used for measuring the physical properties of a planetary atmosphere or ring system. Satellites carrying onboard GNSS-Radio occultation instruments include CHAMP, GRACE and GRACE-FO, MetOp and the recently launched COSMIC-2.[1]
