基于SMP2的卫星区域可见性仿真分析

全球或区域可见性分析是导航系统定位、测速和授时性能仿真分析与评估的组成部分。采用基于仿真模型可移植性标准(SMP2)的模型开发与集成方法,开发导航系统仿真模型,分析伽利略卫星导航系统在中国格网的区域可见性。附带介绍了自主研发的PIM设计工具、代码生成器、SMP2运行时环境等支持SMP2标准的软件工具。基于SMP2的仿真模型开发与集成方法具有模型可重用性好、可移植性强、手工开发代码数量少、代码质量高的优点,可在卫星导航系统定位、测速、授时体制验证与精度分析工作中得到推广应用。

Simulation Analysis of Satellites' Regional Visibility Based on SMP2

The analysis of satellites' global or regional visibility is a part of the simulation analysis and evaluation of the Navigation System's performance on positioning, velocity-measuring and time-telling. The SMP2-based models development and integration method was applied to develop simulation models of Navigation System, and analyze the regional visibility of Galileo Satellite Navigation System in China. Besides, the independent-developed software tools that support SMP2 standard, such as PIM design tool, code generator and SMP2 runtime environment, were introduced. The development and integration method of simulation models based on SMP2 has the following advantages:fine reusability, nice portability, less hand-writing codes and high-quality codes. This method can be spread and applied in the simulation analysis and evaluation of the Navigation System's performance on positioning, velocity-measuring and time-telling.
