The SDC operated by ASF is a National Aeronautics and Space Administration funded Distributed Active Archive Center. The SDC specializes in SAR data collection, processing, archiving, and distribution. The SDC provides SAR data from a variety of satellites and aircraft as well support services to U.S. Government-approved researchers.
The STGS operated by ASF manages two antennas, a 10-meter system and an 11-meter system. Both antennas are capable of X-band and S-band downlink and, in addition, the 11-meter system provides support S-band command uplink. The STGS is part of the National Aeronautics and Space Administration Ground Network system.
The Alaska Satellite Facility (ASF) of the Geophysical Institute (GI) at the University of Alaska Fairbanks (UAF), downlinks, processes, archives, and distributes remote-sensing data to scientific users around the world.
ASF's mission is to make remote-sensing data accessible.
