Remote sensing satellite load data dynamic simulation device

Abstract

A remote sensing satellite load data dynamic simulation device belongs to the field of remote sensing satellite ground test. The remote sensing satellite load data loading device aims to solve the problem that an existing remote sensing satellite load data loading device cannot comprehensively simulate data changes in actual operation of satellite loads due to the fact that the form of loaded analog data is fixed. The device comprises a dynamic real-time simulation module and a dynamic real-time loading module, and the dynamic real-time simulation module is used for generating image type loading simulation data and non-image type loading simulation data; meanwhile, receiving hardware parameter configuration data of the dynamic real-time loading module; and the dynamic real-time loading module is used for loading the image class loading analog data and the non-image class loading analog data to corresponding loads on a satellite through a multi-path customized data interface. Accordingto the invention, the high-speed data real-time loading module and the low-speed data real-time loading module are adopted to carry out real-time loading on satellite load simulation data, so that thesatellite ground test time is greatly shortened, and the flexibility and reliability of satellite test work are improved.

Description

technical field [0001] The invention relates to a dynamic simulation device for load data of remote sensing satellites, belonging to the field of ground testing of remote sensing satellites. Background technique [0002] Remote sensing satellites play an important role in the fields of natural exploration, disaster prevention, and national defense. The realization of their functions depends on the payloads such as remote sensing cameras, data processors, link managers, and satellite multiplexers. Due to the difficulty of research and development of payload technology, its delivery time is usually far behind other satellite subsystems, which seriously increases the time for satellite final assembly ground testing. [0003] The remote sensing satellite load data loading equipment is used to simulate the data output of each payload of the remote sensing satellite and load it on the satellite during the ground test of the remote sensing satellite, so as to realize the comprehens...
