  • Cryosat-2

    ESA’s CryoSat-2 mission was launched in 2010 with the primary purpose of monitoring the cryosphere system. The satellite is characterized by a Low-Earth, non- Sun-Syncronous orbit, with an altitude of circa 730 km and coverage of ±88° (92° inclination). Its repeating cycle is of 369 days, with 30-day sub-cycles. The sophisticated design of the onboard SAR/Interferometric Radar ALtimeter (SIRAL) allows applications also on inland water and ocean, with promising results on coastal areas. SIRAL operates in three different modes, namely Low Resolution Mode (LRM), Synthetic Aperture Radar (SAR) and Inteferometric SAR (SARIn). The geographical extent of each mode is determined by a dynamic global mask, which changes according to the presence of ice - in the interested areas - or eventually to user requests.

  • Jason-3

    Jason-3 is the third satellite of the Jason series. It was launched in January 2016 and it is currently monitoring the ocean surface on the same ground-track as TOPEX/Poseidon, Jason-1, and Jason-2. Such ground-track configuration has allowed a continuous monitoring of the oceans, providing data with an uninterrupted timeseries of circa 25 years.

  • SARAL

    SARAL is a mission born from the collaboration between CNES and ISRO. SARAL was launched in 2013 with the objective of monitoring the ocean surface. For this purpose, SARAL carries two fundamental instruments: a receiver for the ARGO float system (link to ARGO), the ARGOS-3, and the first altimeter operating in Ka band, namely AltiKa. The High frequency of Ka band improves the accuracy in range measurements as well as measurements over ice and coastal areas. SARAL flies in a LEO, Sun-synchronous, polar orbit at 800 km of altitude, and with a repeat cycle of 35 days.

  • Sentinel-3A

    The Sentinel satellites are designed within the European Commission Copernicus programme, whose aim is to monitor our planet for environmental, social, and economic purposes. The Sentinel-3 series is focused on ocean observation, with further applications also on land and atmosphere. The mission is based on two identical satellites flying on a polar, Sun-synchronous orbit at altitude 815 km, inclination of 98.6° and a repeat cycle of 27 days. The first satellite, Sentinel-3A was launched in February 2016.
