摘要

The advanced spacebome thermal emission and reflection radiometer (ASTER) was developed by the Ministry of Economy, Trade and Industry (METI) for installation in the EOS-AM1 spacecraft. The ASTER consists of a visible and near-infrared radiometer (VNIR), a short-wave infrared radiometer (SWIR) and a thermal infrared radiometer (TIR). Two cryocoolers are required to cool the infrared detectors for the SWIR and the TIR subsystems. Two cryocoolers have been operating in orbit for over 22000 hours. The temperature of each detector was stabilized in the allowable temperature range. Long-term data have been acquired on the cooling performance and power consumption (or motor current) under normal operating conditions for each cryocooler, and they have also been evaluated based on the detector temperature and temperature stability in this phase. In this paper, the following are described: outline of ground test results and performance of the ASTER cryocooler in orbit for over 22000 hours.
