But Four Amazing Satellites!
NASA has teamed up with three other international space agencies.
Each of these agencies has built Earth orbiting satellites which carry a
Synthetic Aperture Radar (SAR) instrument to study and monitor the Earth and its
global climate.
These satellites have a Sun-synchronous, near polar, quasi-circular orbit, and
ensure highly repetitive coverage of ice zones even during Polar winters.
NASA has built two ground stations to receive SAR data from these 4 satellites. One is called the Alaska SAR Facility at the University of Alaska Fairbanks,
which also processes and distributes SAR imagery. ASF is managed by UAF and
was implemented together with the Jet Propulsion Laboratory. The other
station is The McMurdo Receiving Ground Station in Antarctica, which sends
the data it receives to ASF for processing.
