Alaska Satellite Facility
Delivering Remote Sensing Data Since 1991

Data Options


Carried aloft by a NASA rocket launched from Vandenburg Air Force Base on November 4, 1995, RADARSAT-1 was launched by NASA for Canada. The satellite was equipped with a C-band SAR and was able to collect data using a variety of swath widths, incidence angles, and resolutions.

Most important, for scientists interested in Antarctica, RADARSAT-1 could be maneuvered in orbit to rotate the normally right-looking SAR to a left-looking mode. This “Antarctic Mode” yielded nearly instantaneous, high-resolution views of the entirety of Antarctica.

The first Antarctic Mapping Mission (AMM-1) began on September 9, 1997, and was successfully concluded on October 20, 1997. AMM-2 began on September 3, 2000, and was successfully concluded on November 17, 2000.
