Embodiment Construction

[0023] Please refer to FIG. 1 first. FIG. 1 is a schematic structural diagram of the precision orbit determination system of the present invention.

[0024] A precision orbit determination system for medium and low orbit satellites based on the Galileo positioning system and satellite laser ranging, including the running Galileo system (only satellite A (1) and satellite B (2) are listed in Figure 1), with its own laser The mid-low orbit satellite (3) of the reflector and its onboard Galileo receiver (6), the satellite laser range finder A (4) of the ground test point and its Galileo receiver A (7), and the satellite laser range finder B (5) and its Galileo receiver B (8). Among them, it needs to be pointed out that the European Galileo program is a medium-altitude circular orbit (MEO) program. The system will consist of 30 medium-altitude circular orbit satellites and 2 ground control centers, of which 27 satellites are working satellites and 3 are standby. The altitude of t...

Abstract

A method for realizing precise orbit determination of low-medium orbit satellite utilizes Galileo positioning system, satellite laser distance measurement technique and integrated precise orbit determination new means to optimize space-ground orbit determination system for realizing precise orbit determination of low-medium orbit satellite equipped with laser reflector.

Description

Technical field: [0001] The invention relates to a system and method for precise orbit determination of low-orbit satellites with self-contained laser mirrors. [0002] Specifically, it is a new type of high-precision orbit determination system for medium and low orbit satellites built through the Galileo positioning system, satellite laser ranging, and Galileo receiver development technology. It is a new method that effectively solves satellite precision orbit determination. Background technique: [0003] High-precision orbit is the basis for effective control of satellites. The rapid development of my country's aerospace industry has put forward higher requirements for the calculation accuracy of satellite orbit determination, forecast and control. To make full use of satellite resources for scientific research, it is first necessary to improve the orbit determination accuracy of low- and medium-orbit satellites, and the radial orbit determination accuracy is required to ...
