| Abstract: | According
to the characteristics of remote sensing satellite receiving task, this paper an
alyses the main constraint condition of multi station multi satellite task sch
edul
in
g, proposes two optimization object functions, establishes optimal task schedul
ing model based on constraint satisfaction optimization problem, and combines me
t
hod of Greedy algorithms and constraint propagation to solve multi stat
ion multi satellite task scheduling problem.
The optimization model and the solution algorithm have been successfully appl
ied in the daily operation of remote sensing satellite data receiving stations. |
