Ground simulation system based on small satellite intelligent technology

Abstract

The invention discloses a ground simulation system based on a small satellite intelligent technology; the system comprises an embedded real-time control system, an intelligent identification system, a data compression system, a data routing system, a gesture positioning system and a wireless communication system which are mutually connected through a controller area network (CAN) bus; and a PC104 is used for carrying a VxWorks embedded operation system to control in real time, a digital signal processor (DSP) is adopted to operate intelligent cloud detection, identification, compression and other algorithm, and a field programmable gate array (FPGA) is adopted to receive and forward the data. The ground simulation system based on the small satellite intelligent technology has the beneficial effects that software and hardware structures related to an intelligent design are extracted based on an existing small satellite structure, the ground simulation system applicable to various algorithm simulation is constructed, different needs are segmented and combined, so that the system not only can complete the verification of a single sub system but also can complete the test for the overall performance of the system; and due to a large amount of ground actual simulation and emulation, the times of a satellite-ground joint test can be reduced, the risks brought by the joint test are reduced, and the efficiency in researching and developing on-board software is improved.

Description

technical field [0001] The invention relates to a simulation system, in particular to a ground simulation system based on the intelligent technology of small satellites. Background technique [0002] At present, with the development of satellite technology, the requirements for satellite simulation system are getting higher and higher. The satellite ground simulation system can simulate and improve the four systems of satellite identification, observation, compression and transmission on the basis of cost saving, safety and reliability. In order to improve the shortcomings of the simulated target satellite observation method, such as single observation method, fixed compression algorithm, and simple transmission mode, and put forward effective solutions and processing schemes. [0003] The current satellite simulation system has the following problems: [0004] 1) The design cycle is long, the spaceborne intelligent observation software design cycle is long, and the softwa...
