Abstract

The ATSR is an infrared imaging radiometer which has been selected to fly aboard the ESA Remote Sensing Satellite No. 1 (ERS1) with the specific objective of accurately determining global Sea Surface Temperature (SST). Novel features, including the technique of along track scanning, a closed Stirling cycle cooler, and the precision on-board blackbodies are described. Instrument sub-systems are identified and their design trade-offs discussed.
