Abstract

The present invention provides a method and system for controlling the freezing and sweeping attitude of a remote sensing satellite on the ground. Calculate the ground track angle of the condensation sweep observation at the time of passing the top; calculate the ground track tracking point based on the time series and the ground track angle; ; According to the direction of the optical axis of the earth remote sensing satellite load, determine the freezing and sweep attitude of the earth remote sensing satellite located at the current control point.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellites, in particular to a method and system for controlling the sweeping attitude of an earth remote sensing satellite. Background technique [0002] With the development of high-tech and the promotion of demand, remote sensing micro-nano satellites have the advantages of light weight, small size, low power consumption, short development cycle, high functional density, high performance-price ratio, and formation networking. Environmental monitoring, land planning, geographic surveying and mapping and other scientific research, national defense and commercial fields have shown good development prospects. [0003] With the improvement of high-resolution remote sensing mission requirements and target accuracy requirements, the relationship between the monitoring ability of remote sensing satellite cameras and the imaging quality of their optical axis positions during missions has become m...
