The SAOCOM 1B spacecraft is the second of the two SAOCOM constellation satellites. It is tasked with hydrology and land observaion, and will also operate jointly with the Italian COSMO-SkyMed constellation in X-band to provide frequent information relevant for emergency management.
SXM-7 is a large high power broadcasting satellite for SiriusXM's digital audio radio service (DARS). Space Systems/Loral (SS/L) got in July 2016 the contract to build the two satellites based on their SSL-1300 bus - SXM-7 and SXM-8. Both operate in the S-band spectrum. Each satellite will generate more than 20-kW of power and will have a large unfurlable antenna reflector, which enables broadcast to radios without the need for large dish-type antennas on the ground. SXM-7 is meant to replace the XM-3 satellite.
