Abstract

The invention provides a satellite orbit determining method and device based on maximum model decomposition. The satellite orbit determining method comprises the steps that based on the KAM principle, a Fourier series expansion model of position coordinates of a satellite is established when the satellite operates on an orbit; according to the descending order of amplitudes, the Fourier series expansion model of the position coordinates is decomposed, and a decomposed similar series expansion model of the position coordinates is obtained; based on the actual observation values of the position coordinates of the satellite when the satellite operates on the orbit, the amplitudes and the corresponding frequencies in the similar series expansion model of the position coordinates are determined; through the similar series expansion model of the position coordinates, the position coordinates of the satellite on the orbit at any moment are predicated. The satellite orbit is determined more rapidly and conveniently by the adoption of the satellite orbit determining method and device based on maximum model decomposition, the satellite orbit determining method and device based on maximum model decomposition is practical, only the frequencies and the amplitudes of the satellite orbit need to be computed and stored in the predication process, storage resources are saved, and the processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of satellite orbit determination, in particular to a satellite orbit determination method and device based on maximum modulus decomposition. Background technique [0002] my country's self-developed marine dynamic environment satellite Haiyang No. 2 (HY-2A) was successfully launched on August 16, 2011 as planned. The microwave remote sensors it carries mainly include microwave scatterometer, radar altimeter, scanning microwave radiometer and calibration microwave radiometer, etc. Satellite orbit determination algorithm research and related software development is a key link in the independent marine dynamic environment satellite microwave remote sensing processing technology, which will make important contributions to improving the application efficiency and service level of marine satellites. [0003] The process of satellite orbit determination mainly involves the accuracy of observations and their geometr...
