Description

technical field [0001] The invention relates to a satellite intelligent star service system and a realization method thereof, belonging to the field of satellite star service systems. Background technique [0002] The on-orbit application of artificial intelligence is one of the directions for the development of next-generation satellites. On-orbit intelligent application modes such as intelligent mission planning, fault self-diagnosis, and intelligent image recognition have begun to emerge. At the same time, artificial intelligence such as machine learning, pattern recognition, and deep learning Various algorithms have put forward more urgent demands for on-orbit intelligence to improve the capabilities of on-board software and hardware. [0003] At present, satellite in-orbit intelligent technology has the following deficiencies: [0004] 1) Existing satellite systems can only achieve simple on-orbit algorithm calculations.

AI Technical Summary

Problems solved by technology

[0004] 1) Existing satellite systems can only achieve simple on-orbit algorithm calculations. For complex image recognition such as remote sensing target detection and other artificial intelligence algorithms, due to limited computing resources and power consumption on the star, most of them still use traditional ground reception. data and methods of processing data;

[0005] 2) The existing star system still adopts the traditional embedded system, and the task scheduling and intelligent computing functions are implemented on the same processor, the data processing efficiency is low, and only simple intelligent computing can be performed;

[0006] 3) The execution of on-board missions in the existing satellite system usually requires ground cooperation, especially large-scale calculations, and the real-time performance is poor. However, more and more satellites have put forward higher requirements for the real-time performance of on-board missions, which require on-board on-orbit smart support
