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.
