چکیده انگلیسی

Space system simulation is involved in many fields, such as space remote sensing, space communication, navigation and positioning, and deep space exploration, etc. Even though the HLA simulation technology is adopted, simulation systems for different fields may easily be chimneys and construction work may be repeated, if they are developed separately. So, a simulation environment which can be shared by different HLA simulation federations of space system is needed. In this paper, a new scheme of simulation environment is proposed, in which several mechanisms ensure that the simulation environment is highly universal and reusable.

مقدمه انگلیسی

Along with the development of space technology, more and more people use simulation technologies to simulate space systems and establish simulation environments, such as STK (Satellite Toolkit) [1], SCT (Spacecraft Control Toolbox) [2], EuroSim [3] and Open-SSESSAME [4], aiding space system design and optimization. Space systems are often simulated together with relative ground support systems and ground user terminals, for evaluating the overall performance or effectiveness of the system. The complex system consisting of these systems is called meta-system [5], [6], [7] and [8] or system of systems. The space system simulation dealing with a space meta-system is called space meta-system simulation. It is difficult to simulate these complex systems using hardware-in-loop simulation methods. The distributed mathematical simulation, for example, HLA (high level architecture) simulation [9], [10], [11] and [12], is needed to distribute objects reasonably into many computers and simulate the information flows of the whole space meta-system using information exchanges among the simulated objects.

نتیجه گیری انگلیسی

The advantages of our design are as follows. The simulation objects defined uniformly in advance can be easily inherited by different HLA federates. The data resources and the fundamental simulation models can be shared by different simulation systems. Therefore, the simulation environment is highly universal and reusable. A disadvantage is that the prophase work is a little difficult since the space system simulation object templates need to be designed carefully. Though our simulation environment is not completely constructed, the design is proved to be a reasonable and feasible one by our construction practice.
