Be illustrated in figure 2 the structural representation of a kind of satellite task planning system in the embodiment of the present invention, this system contains server 201 and M client 202, each client 202 can with server 201 communication, client 202 can arrange service centre's (satellite task planning system) in FIG, also can be arranged in Subscriber Unit (satellite user demand proposes department), not limit the position of client 202 in embodiments of the present invention.
This satellite task planning system can receive the observation requirements of each user, client 202 in this satellite task planning system can get observation requirements, certainly can be that a client 202 obtains observation requirements or multiple client 202 to obtain observation requirements, then the state synchronized parameter of all usable satellites also can be broadcast to M client 202 by server 201.
Client 202 based on the observation requirements received and usable satellite state synchronized parameter, can generate corresponding mission planning result, and mission planning result is back to server 201.
Server 201 is after receiving mission planning result, and server 201, by task based access control program results request satellite resource, obtains the response message that task based access control observed result returns, and finally response message is back to corresponding client.
In the above-described embodiment, in this satellite task planning system, client 202 can obtain observation requirements, then client 202 can be carried out independently calculation process and obtained satellite task program results, thus make satellite task planning system can propose the stage at observation requirements just satellite task planning can be carried out, thus improve the ageing of satellite task planning system.
