ICESat (Ice, Cloud, and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. From 2003 to 2009, the ICESat mission provided multi-year elevation data needed to determine ice sheet mass balance as well as cloud property information, especially for stratospheric clouds common over polar areas. It also provided topography and vegetation data around the globe, in addition to the polar-specific coverage over the Greenland and Antarctic ice sheets.
All ICESat flight operations activities were conducted by LASP in the ICESat Mission Operations Control (IMOC).
Flight operations activities included:
- Monitoring the health and safety and commanding of the observatory during realtime operations.
- Post-pass telemetry data acquisition: s-band data playbacks, GPS data
- Mission planning and scheduling
- Command generation
- Engineering data processing and analysis
- Orbit and attitude determination
The IMOC received telemetry data and sends commands via the NASA Ground Network and from commercial tracking stations contracted by NASA.
There were no LASP instruments on board ICESat.
