M&s-based Space Remote Sensor Design & Analysis

Space Remote Sensor (SRS) is a complicated system involving optics, mechanism, electric and thermal. Utilizing Modelling and Simulation (M&S) in the development of SRS can expedite the design process, reduce costs and minish risks. This article first introduces the concept of Model Based System Engineering (MBSE), then expatiates the characteristics of VP. MBSE provides a methodology for complicated and large scale systems. VP can act as the connection between design, analysis and manufacture. After that, the article gives an example to illustrate how to utilize M&S in the development of SRS. The author first builds a simple virtual prototype (VP) of SRS. Then the performance change of SRS under sun radiation is analyzed by the VP. The simulation results show that the performance of SRS is not sensitive to radial temperature gradient
