Abstract

The invention discloses an image navigation/registration demonstration and verification system based on a real-time simulation platform and a control method. The system comprises a data management computer, an image navigation and registration coprocessor, a payload simulator based on the real-time simulation platform, a dynamics and attitude and orbit control computer simulator based on the real-time simulation platform, a payload work instruction generation tool, a performance demonstration, verification and evaluation system and a ground telemetering and telecontrolling system, wherein the payload simulator is used for simulating the in-orbit work state of a satellite payload, and the dynamics and attitude and orbit control computer simulator is used for simulating the in-orbit work state of a satellite attitude and orbit control subsystem. The system and the method can be used for carrying out evaluation, demonstration and verification on a design result during the designing of an image navigation and registration subsystem and can also be applied to failure determination and inversion during the in-orbit operation of a satellite. The system and the method have the advantages that the practical engineering problem that ground verification is carried out when dynamically-compensated image navigation and registration is carried out on the satellite is solved, and the validity of an image navigation and registration design is guaranteed.

Description

technical field [0001] The invention relates to satellite image positioning and registration technology, more specifically, relates to a method for demonstrating and controlling the image positioning and registration technology of real-time dynamic compensation algorithm on the satellite. This method can be used to evaluate and demonstrate the design results during the design process of the satellite image positioning and registration subsystem, and can also be used for fault judgment and inversion during the satellite's in-orbit operation. Background technique [0002] With the continuous development of aerospace remote sensing and earth observation technology, the resolution of remote sensing satellite images is getting higher and higher, and its application is becoming more and more extensive. The unit proposed the on-orbit application of Image Navigation and Registration (INR) to determine the geographic location of each pixel in the meteorological cloud image with high ...
