On-satellite autonomous imaging task planning system

Abstract

The invention provides an on-satellite autonomous imaging task planning system. The on-satellite autonomous imaging task planning system comprises a satellite orbit recursion forecasting module, an on-orbit imaging task forecasting module, an on-orbit imaging task design module, an on-orbit task synthesis module, an on-orbit imaging task conflict optimization sorting module and an on-orbit imagingimplementation module. A satellite user only needs to send longitude and latitude of an imaging area to a satellite. The satellite autonomously calculates the imaging time, calculates and sets imaging and control parameters and intelligently arranges imaging, a user does not need to understand a complex satellite design and use method, then imaging of a target area is completed conveniently, rapidly and efficiently, and meanwhile the situation that instruction arrangement errors affect the safety of the satellite is avoided. The on-orbit task synthesis module synthesizes adjacent tasks meeting conditions according to constraints such as satellite attitudes, imaging sensors and imaging time to generate a new task sequence.

Description

technical field [0001] The invention relates to the technical field of satellite mission planning systems, in particular to an on-board autonomous imaging mission planning system. Background technique [0002] At present, most remote sensing satellites require ground personnel to arrange complex imaging tasks, with a large amount of command data and cumbersome process; the increase in the number of satellites in orbit and the geographical restrictions of the measurement and control network limit the uplink tasks; the specific environment on the satellite is not clear when imaging , It is easy to cause satellite safety problems; satellite users are inconvenient to use, require professional aerospace knowledge, and the operation is complicated. [0003] Therefore, how to design a system in which the user does not need complex operations and professional knowledge, but only needs to send the latitude and longitude of the imaging area to the satellite, and the satellite automati...
