The Design And Implementation Of The Plug-and-play Software System Based On Spa-s

With the rapid development of spaceborne devices,the demand for satellitespecific satellites for rapid assembly,testing,deployment,response and transmission has become increasingly greater.In order to meet the future military space mission and the demand for fast-acting satellites,American Institute of Aeronautics and Astronautics(AIAA)officially released the Space Plug-n-Play Architecture(SPA)Standard in 2013.Foreign countries have already implemented the products according to the SPA standards,but no relevant studies have been carried out in China.Based on the comprehensive investigation of the existing theory and practice of SPA technology at home and abroad.This article design and implement the SPA-S application layer software system compatible with SpaceWire.Which fully complies with the SPA standard and has the following characteristics:1)Implement SPA standard software function,can fully resolve standard xTEDS,SPA messages.2)The ability to plug and play,configure,and quickly integrate.3)An ASIM module that supports the non-spacewire interface sensor to the SpaceWire subnet4)Implement a hardware and software test system that supports the plug-and-play and flexible integration capabilities of SpaceWireThis article has the following two innovations: Based on the SPA standard protocol logic model,design and implementation of SPA-S plug and play architecture;Presented the SPA network management technology with SpcaeWire.The work in this paper will help accelerate the development of satellites and improve the throughput and performance of satellites,which is of great significance to the modular,universal,plugand-play and portable development of satellites in the future.
