摘      要：Environment and disaster monitoring and forecasting small satellite constellation A and B satellites(HJ-1-A,B) are called environment and disaster reduction satellites A and B for *** constellation adopts a 10:30LT sun-synchronous circular orbit,with orbit altitude of ***1-A and HJ-1-B are distributed with a phase difference of 180° in the same orbital plane,so as to enhance the time resolution of earth *** satellites have orbit maintenance capability,the lifetime is 3 *** satellites adopt CAST968 *** wide-coverage multispectral CCD cameras with resolution 30m and width 700km,a super-spectral imager with resolution 100m and width 50km as well as a data transmission subsystem of 120Mbit/s are deployed on HJ-1-A,which also carries Ka communication testing equipment of ***-1-B has two wide-coverage multispectral CCD cameras(the same as satellite A),one infrared camera with resolution 150m and width 720km and a data transmission subsystem of 60Mbit/*** coverage period of the wide-coverage multispectral CCD camera is 48 *** revisit period of super-spectral imager is 96 hours and the coverage period ofinfrared camera is 96 hours.
