Abstract

The invention provides a to-be-observed task determination method for multi-satellite synergistic earth observation and relates to the field of earth satellite observation. According to the to-be-observed task determination method for multi-satellite synergistic earth observation provided by the embodiment of the invention, each satellite center obtains corresponding observation tasks and an ephemeris of each controlled satellite, and a first task set of observation tasks executed by all controlled satellites of the satellite center is calculated for the observation tasks of the satellite center and the ephemerides of the controlled satellites through a genetic algorithm, wherein the first task set carries different observation states of the satellite to the tasks; after the first task set of the satellite center is confirmed, an optimal solution with maximized total observation benefit and lowest total energy consumption in all the satellites is calculated through the genetic algorithm, and a second task set can serve as a reference for task execution by an appointed satellite center, so that a scheme for searching a global optimal solution is finished by the genetic algorithm.

Description

technical field [0001] The invention relates to the field of earth observation satellites, in particular to a method for determining tasks to be observed for multi-satellite coordinated earth observation. 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 observation has brought unpreceden...
