To-be-observed task determination method and device of multi-satellite earth synergetic observation

Abstract

The invention provides a to-be-observed task determination method and device of multi-satellite earth synergetic observation, and relates to the earth satellite observation field. The to-be-observed task determination method of the multi-satellite earth synergetic observation comprises the following steps: enabling each satellite center to acquire a corresponding observation task and an ephemeris of each controlled satellite, computing a first task set of observation tasks executed by all the controlled satellites in each satellite center aiming the observation task of each satellite center and the ephemerides of the controlled satellites by using a genetic algorithm, and computing an optimal solution with maximum total observation benefit and lowest total energy consumption in all the satellites by using the genetic algorithm after the first task set of each satellite center is determined, namely, a second task set; if the second task set meets a preset optimal condition, executing the task by the appointed satellite center by using the second task set as the reference, so that the globally optimal solution search is finished by using the genetic algorithm.

Description

technical field [0001] The invention relates to the field of satellite observation of the earth, in particular to a method and a device for determining a task to be observed for multi-satellite coordinated observation of the earth. Background technique [0002] As one of the most important categories in the spacecraft family, earth observation satellites mainly use spaceborne sensors installed on the satellites to detect the earth's surface and lower atmosphere, and then obtain relevant information. Earth observation satellites have unique advantages such as wide coverage area, long duration, and not limited by airspace and national boundaries. At present, earth observation satellites have played an important role in many fields such as military reconnaissance, disaster prevention and mitigation, meteorological observation, environmental protection, modern agriculture, and land surveying and mapping. [0003] At present, the rapid development of the demand for earth observa...
