Abstract
With the rapid development of earth observation technology, the resolution of payload is getting higher and higher, and the amount of data transmitted by remote sensing satellite is getting larger and larger. In order to solve the contradiction between the remote sensing data acquired by the satellite and the transmission ability of the satellite-to-ground transmission links. Using new transmission systems, such as high-order modulation of high speed transmission and variable code modulation (VCM), to improve the efficiency of satellite-to-ground transmission links within limited frequency band resources has become the development trend of satellite-to-ground data transmission for new generation remote sensing satellites. In this paper, the high rate digital demodulator supporting VCM mode is designed, and the overall hardware design and software design, as well as the key point VCM design are introduced. Finally, combining with the ground system engineering of GF-7 satellite, the function and performance of the high-speed demodulator supporting VCM are verified, and the engineering application is introduced.
