Abstract
A simulation software for efficient analysis and rapid planning of multi-satellite earth observation mission is designed to solve the problem that it is difficult to make fast decisions for multi-target and multi-constraint earth observation mission. The software is developed with C++ programming language, which has the advantages of modular design, good portability, fast running speed and less occupation of resources. Meanwhile, the input and output interfaces of the software adopt the file format of an extensible mark-up language, which can easily realize cross-platform (Windows, Linux, etc.) data exchange. The simulation results show that the software has high execution speed and precision.
Highlights
Earth observation plays an important role in national economic and social development and is an important part of a country's comprehensive strength 1, 2
The simulation platform can be applied to the simulation of satellite earth observation mission planning and its attitude maneuver strategy and can provide certain support for the analysis, design, and evaluation of large systems, enabling users to make decisions quickly based on the planning results
The description of the position parameters of targets, area targets, and general trajectory targets on the earth's surface is usually based on the earth-centered earth-fixed (ECEF) frame, but the coordinates in the earth-centered inertial (ECI) frame need to be used in subsequent access computations
Summary
Earth observation plays an important role in national economic and social development (such as land census, emergency and disaster relief, etc.) and is an important part of a country's comprehensive strength 1, 2. The number of satellites in orbit is still increasing, the limited resources of earth observation satellites are extremely precious compared with the growing observation demand. It is a more urgent problem on how to make overall planning of satellite resources and accomplish corresponding task demands with minimum resources. The simulation platform can be applied to the simulation of satellite earth observation mission planning and its attitude maneuver strategy and can provide certain support for the analysis, design, and evaluation of large systems, enabling users to make decisions quickly based on the planning results. Combined with the case test of multi-satellite to target and area target, the simulation ability of the software to the actual task is demonstrated
