Embodiment Construction

[0054] The present invention proposes an online dynamic planning realization terminal including n micro-onboard computers, n Beidou short message transceivers, n measurement and control transponders, 2n ADSP-SC589 DSPs, n NAND Flash memories, 2n SRAMs, 2n A PROM, 2n 82C250 CAN bus level conversion chips, and n CAN buses.

[0055] The ground user terminal n+2 establishes communication with the ground measurement and control station n+1 through the Internet. The multi-satellite system is composed of satellite 1, satellite 2, ..., satellite n (i=1, 2, ..., n), and each satellite establishes a two-way wireless connection with the ground measurement and control station through the measurement and control transponder i-5, and the measurement and control transponder Connect with Beidou short message transceiver i-4. The mutual access communication link is established between the satellites through the Beidou short message transceiver.

[0056] In a multi-satellite system, the struc...

Abstract

The invention provides an online dynamic task planning terminal and planning method for medium and low orbit micro satellites. The terminal of the invention adopts an online task planning module of aparallel processing structure, and when the satellite maintains communication with a ground measurement and control station, the communication and coordination among multiple satellites, and dynamic task planning are achieved in combination with a Beidou short message transceiver. The method of the invention adopts the form of an auction contract network, and comprises: processing auction rights,selecting a dominant satellite, and selecting the current auction task. The dominant satellite performs bidding on member satellites for the task. A bidder performs task bidding according to an own state. A tenderee completes bidding evaluation according to a bidding evaluation strategy and selects a contract satellite. Contract establishment, and process monitoring and contract information updateare completed, and the contract is terminated after the task is completed. By adoption of the online dynamic task planning terminal and planning method provided by the invention, the online dynamic task distribution and rational planning of a plurality of medium and low orbit micro satellites can be achieved, the efficiency is relatively high, the planning result is feasible, and it has practicalsignificance for improving the on-orbit autonomy and joint planning capability of the micro satellites.

Description

technical field [0001] The invention relates to a mission planning device for a tiny remote sensing imaging satellite for earth observation. The invention also relates to a task planning method for a tiny remote sensing imaging satellite for earth observation. Specifically, it is a task online dynamic planning terminal and planning method for small remote sensing satellites in low and medium orbits, which can quickly respond to dynamic environments, and can realize multi-satellite task allocation and collaborative planning. The terminal belongs to the distributed satellite system platform a part of. Background technique [0002] The operating environment of satellites in orbit is complex. At present, the command, measurement and control instructions of imaging satellites mainly come from the ground measurement and control system. To make a quick response, its observation efficiency cannot be fully utilized. In order to improve the sensitivity of the satellite to dynamic t...
