Abstract

The invention discloses an image navigation and registering imaging test system and method for a static meteorological satellite. The system comprises a satellite support, a satellite body, a load instrument, a load instrument shading cover, a load instrument feature point measurement target ball, a collimator, and a laser tracker measurement shaft. The satellite body is located on the satellite support, and the satellite body and the load instrument shading cove are connected with the load instrument. The system can carry out the quantitative verification of an image navigation and registering scheme at the stage of satellite development.

Description

technical field [0001] The invention relates to a stationary meteorological satellite, in particular to an imaging test system and test method for image navigation and registration of the stationary meteorological satellite. Background technique [0002] In numerical weather forecasting, it is necessary to locate complex regional weather, track the development trend of severe weather, and generate cloud image animations. This requires accurate absolute geographic location of images and accurate registration of relative positional relationships between adjacent images. The accuracy of image navigation registration is related to the processing accuracy of quantitative remote sensing products such as weather diagnosis, cloud image analysis, and disaster monitoring applications. Due to the small size of the detector array of the meteorological geostationary satellite remote sensing instrument, it is impossible to complete the regional imaging through a single frame. It is necess...
