Problems solved by technology
The current conventional spaceborne data uploading system usually adopts the traditional architecture of frequency converter + demodulator + baseband processor. The hardware structure of this traditional architecture is complex, resulting in high weight and power consumption; and the frequency and bandwidth are fixed and limited. The supported data rate is low, which cannot meet the requirements when large-scale auxiliary data tasks such as images are required; and a large number of hardware design changes are required when using across platforms, and the versatility is poor
[0003] In addition, in terms of transmission mechanism, the current conventional spaceborne data uploading system adopts the frame-by-frame uploading method. After each frame is sent, it is necessary to check the on-board count, which is used as a sign of the successful transmission of each frame before the next frame is transmitted. , this transmission mechanism is very inefficient and takes up a lot of on-board resources

Description
technical field [0001] The embodiment of the present invention relates to satellite communication technology, in particular to a satellite broadband data uploading system and method. Background technique [0002] At present, the on-orbit data injection function has become a standard function configuration of satellite projects. Usually, the on-orbit data injection function is realized by using the satellite's measurement and control channel. The current conventional spaceborne data uploading system usually adopts the traditional architecture of frequency converter + demodulator + baseband processor. The hardware structure of this traditional architecture is complex, resulting in high weight and power consumption; and the frequency and bandwidth are fixed and limited. The supported data rate is low, which cannot meet the requirements when large-scale auxiliary data tasks such as annotating images are required; and a large number of hardware design changes are required for cro...
