Abstract: In order to improve the development efficiency of commercial satellite house-keeping software, reduce the impact of satellite component product development progress on the whole satellite software development, and facilitate satellite batch production, a design method of configurable satellite electronics semi-physical simulation system is proposed in this paper. The electronics simulation system is composed of OBC, communication interface department, on-board electronics stand-alone simulation part and system test part. Using the configurable, universal, highly integrated and modular design ideas, the OBC with configurable characteristics, flexible and configurable multi-functional on-board electronics single-unit simulation simulator, reconfigurable communication interface and intelligent system test interface integrate a set of configurable satellite electronics simulation system. The results show that the system can provide semi-physical simulation experimental data for the whole satellite, and meet the development requirements of satellite house-keeping software of different types. At the same time, it has the function of connecting physical single machine for simulation test. The electronic simulation system can improve the development efficiency of satellite service software, is conducive to the mass production of satellites, and has important engineering significance.

引言

近年來,在各界的共同努力下,,商業(yè)航天開始蓬勃有序發(fā)展,。目前我國航天衛(wèi)星領(lǐng)域中商業(yè)衛(wèi)星發(fā)射所占比例越來越大,必將成為未來航天產(chǎn)業(yè)發(fā)展的重要方向[1],。傳統(tǒng)衛(wèi)星研制以定制為主,,研究門檻高、周期長,、成本高,,而商業(yè)衛(wèi)星研制模式發(fā)生重大改變,要求衛(wèi)星功能多樣化,、研制周期短,、需求響應(yīng)快。另外商業(yè)衛(wèi)星的研制為了節(jié)約成本和縮短研制周期,,打破傳統(tǒng)航天從電性件,、初樣件到正樣件,逐一環(huán)節(jié)的驗證研制流程,,直接一步到正樣件[2],。商業(yè)衛(wèi)星之所以簡化研制流程,一方面因為采用大量COST器件和高集成設(shè)計技術(shù),,另一方面是因為商業(yè)衛(wèi)星以星務(wù)軟件為核心構(gòu)成衛(wèi)星總體的二級控制系統(tǒng),,使整星處于有序的、可控的,、可配置的,、無競爭的工作狀態(tài),。商業(yè)衛(wèi)星星務(wù)軟件作為整星的控制中樞,其設(shè)計和研制水平對衛(wèi)星的安全性,、可靠性起到關(guān)鍵性的作用,,是衛(wèi)星的核心組成部分。針對商業(yè)衛(wèi)星的研制特點,,如何快速,、高效、可靠地研制星務(wù)軟件變得極為重要,。為了滿足商業(yè)衛(wèi)星星務(wù)軟件研制需求,在工程及理論研究上促進(jìn)星務(wù)軟件技術(shù)的發(fā)展,,可配置化衛(wèi)星電子學(xué)仿真系統(tǒng)設(shè)計研制與實現(xiàn)變得極為重要,。
