Embodiment Construction

[0018] figure 1 It is a flow chart of an embodiment of the satellite orbit determination method provided by the present invention. Such as figure 1 As shown, the execution subject of the following steps may be a server or terminal with high-speed computing function or a chip or module integrated in the server or terminal. The method for determining the satellite orbit specifically includes:

[0019] S101, establishing at least one perturbation model, each perturbation model is used to represent different perturbation factors affecting satellite operation;

[0020] Usually, the actual trajectory of a satellite in space is affected by many perturbation factors. According to the principle of dynamics, a corresponding perturbation model can be established according to each perturbation factor, and each perturbation model is used to represent different perturbation factors affecting satellite operation. For example, the earth's gravitational perturbation model can be establishe...

Abstract

The invention provides a determination method and a determination device of a satellite orbit. According to the determination method of the satellite orbit, a component technology in subscriber identity module card tool kit (STK) is based on, a Runge-Kutta (RFK) method and a time-integration mode of variable step-size are used, an algorithm formula of RFK 7 (8) controlled by a seventh-order integration and an eighth-order error is taken, the position and the speed of the satellite orbit are calculated, and compared with a traditional algorithm, calculating accuracy and calculating efficiency are improved. The determination method of the satellite orbit effectively resolves the problem that low calculating efficiency and calculating accuracy are caused due to big accumulated error when an existing method is used for solving an equation of satellite motion.

Description

technical field [0001] The invention relates to the field of orbit dynamics, in particular to a method and device for determining a satellite orbit. Background technique [0002] Since the first artificial earth satellite entered space in 1957, artificial satellites have had a huge impact on many fields such as economy, military affairs, communications, meteorology, scientific research, cultural life, etc., and have become the main tool for human beings to explore and develop space and earth resources. An important object in the study of astrodynamics. Because the satellite operation is easily affected by many perturbation factors, such as the earth's non-spherical perturbation, atmospheric resistance perturbation, solar light pressure perturbation, solar gravitational perturbation, lunar gravitational perturbation, etc., it is not easy to determine the satellite orbit. [0003] Among the existing methods, Euler algorithm, Runge-Kutta (R-K) algorithm, Automatic Dynamic Anal...
