The device comprises an imaging load control command analysis unit for receiving time synchronization information of a remote-sensing-satellite-spaceborne computer and generating a simulated remote sensing image and a data control command according to a camera controlcommand of the remote-sensing-satellite-spaceborne computer, a data interaction unit for transmitting the simulated remote sensing image and the data control instruction to a simulated remote sensingimage transmission unit, the simulated remote sensing image transmission unit for obtaining a sending image data count value, an image loading rate and a satellite alignment interface time sequence clock number, and sending an image to a corresponding remote sensing satellite image processing load according to the image loading rate; and a simulated remote sending image is determined based on theimage data count value to complete satellite loading. Therefore, the processing capability of the on-board image processing load for the image formed by the novel remote sensing imaging load can be verified fully.

Description

technical field [0001] The invention relates to a remote sensing satellite multi-mode imaging load simulation device, which belongs to the field of remote sensing satellite ground testing. Background technique [0002] Remote sensing satellites play an important role in natural exploration, disaster prevention, national defense and other fields. The realization of remote sensing satellite functions relies on the remote sensing imaging load, data processor, link manager, satellite multiplexer and other payloads on it. Due to the difficulty in research and development of the payload, the delivery time of the payload usually lags far behind that of other satellites. system, which seriously increases the time for ground testing of satellite final assembly. [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 s...
