The experience gained from ROSA radio occultation instruments flying nowadays on three missions (OCEANSAT-2, SAC-D and MEGHATROPIQUE) is presented in this paper. Insights on different aspects of GNSS remote sensing like tropospheric sounding, ionospheric sounding are presented here, compared with state-of-the-art reference data (ECMWF, colocations). Further insight on ROSA instrument from in-flight...
ROSA is a dual-frequency GPS receiver developed for space applications and tailored for GPS radio occultation studies. It is developed and manufactured by Thales Alenia Space Italia under a contract with the Italian Space Agency (ASI) and is designed to establish accurate global profiles of temperature and water vapour in the lower atmosphere. Moreover, ROSA antenna extended coverage allows the retrieval...
