Simulation verification platform and implementation method of micro-satellite formation system

Abstract

The invention discloses an emulation verification platform and an implement method of a micro-satellite team formation system. The platform comprises an emulation and verification main control platform, an emulation primary component, a plurality of emulation secondary components and a plurality of satellite controllers corresponding to the plurality of emulation secondary components. The emulation primary component and the emulation secondary components are communicated with the emulation and confirmation main control platform through an Ethernet network. The emulation main component is communicated with the satellite controllers through wireless fidelity (WiFi). The emulation secondary components and the satellite controllers are connected through recommend standard 232 (RS232) joints. According to the implement method, emulation procedure is started through the emulation and confirmation main control platform so that a real-time emulation environment of a principal and subordinate construction is established; the emulation primary component starts team formation control and sends a control order to the controllers; a control signal is sent to the emulation secondary components through serial ports after emulating calculation by the controllers; a satellite dynamical model and an environmental model are emulated by the emulation secondary components so that state information of a satellite is offered; and emulation data is sent to the emulation and confirmation main control platform for unified management and analysis. According to the emulation verification platform and the implement method of the micro-satellite team formation system, a complete and complex emulation verification function is offered to satellite team formation flight.

Description

technical field [0001] The invention relates to simulation and verification of a control method in the aerospace field. In particular, it relates to a simulation verification platform and an implementation method of a tiny satellite formation system. Background technique [0002] The space environment has become the fourth environment that is closely related to human development except land, sea and air. Compared with traditional single satellites, multi-satellites are more Attracting people's attention, it helps to improve space detection capabilities and ensure the effective and peaceful use of space in our country. It has become the first choice for many space missions. Satellite formation flight can simplify space exploration tasks, expand the observation domain, and remove damaged individuals in a timely manner through system reconstruction. It can also replace satellite loads in the system according to task changes, improving the adaptability of the satellite system t...

Problems solved by technology

At present, the research on domestic satellite formation control system is still in its infancy

Moreover, the related control schemes and algorithms lack the actual analysis environment, and the physical environment needs to invest a lot of risk costs in the early stage of scientific research. Therefore, it is very important to build a satellite formation simulation verification environment for the theoretical research and method verification of the satellite formation system.

[0003] The satellite formation control system is different from ordinary aerospace vehicles. Its system functions are completed by multiple spacecraft in cooperation with each other, so there is complex information interaction.
