| 摘 要： | 在星载导航系统的初步方案规划和算法设计阶段,出于对潜在的折中考虑,高保真的GPS软件仿真器是一种必要且可行的实验室测试手段。本文研究开发了面向空间导航系统设计的GPS量测软件仿真器,它主要针对L1C/A码和载波信号,也就是说该仿真器使用MATLAB编程语言产生C/A码伪距量测和载波量测。论文推导了基于地心惯性坐标系(ECI)的数学模型,用来仿真GPS星座并产生GPS量测数据;在星历数据选择、空间电离层模型和伪距率计算等方面,深入研究并应用一系列增效措施以合理化实现该仿真器。建立的增强型GPS量测仿真器推进了我们现有的星载GPS/INS组合导航系统设计工作,将进一步提升在星载导航系统设计领域的研究。

| Abstract: | At the stage of preliminary scheme and algorithm design for spaceborne navigation systems, a precise and high-fidelity software global positioning system (GPS) simulator is a necessary and feasible testing facility in laboratory environments, with consideration of the tradeoffs where possible. This article presents a software GPS measurements simulator on the L1 C/A code and carrier signal for space-oriented navigation system design. The simulator, coded in MATLAB language, generates both C/A code pseudoran... |
