摘要

Environment and disaster monitoring and forecasting small satellite constellation A and B satellites （HJ-1-A，B）are called“environment and disaste rreduction satellites A and B”for short.The constellation adopts a 10：30 LT sun-synchronous circular orbit，with orbit altitude of 649 km.HJ-1-A and HJ-1-B are distributed with a phase difference of 180°in the same orbital plane，so as toenhance the time resolution of earth observation.The satellites have orbit maintenance capability，thelifetime is 3 years.Both satellites adopt CAST968 platforms.Two wide-coverage multispectral CCD cameras with resolution 30 m and width 700km，a super-spectral imager with resolution 100m and width50 km aswell as a data transmission subsystem of 120 Mbit/s are deployed on HJ-1-A，which also carriesKa communication testing equipment of Thailand.HJ-1-B has two wide-coverage multispectral CCD cameras（the same as satellite A），one infrared camera with resolution 150 m and width 720km and adata transmission subsystem of 60 Mbit/s.The coverage period of the wide-coverage multispectral CCD camera is 48 hours.The revisit period of super-spectral imager is 96 hours and the coverage period ofinfrared camera is 96 hours.
