为了改善软件接收机性能
提出一种微惯性/软件接收机非线性超紧组合方案.分析接收机跟踪环路和微惯性测量组件非线性的基础上
提出了非线性跟踪滤波器和非线性组合滤波器的设计方法.基于跑车实验数据完成了该超紧组合系统性能的试验验证.结果表明
在即时码In-phase/Quadra-phase信号较弱的情况下
该超紧组合跟踪环路仍保持较高的跟踪精度.
In order to improve the performances of software receiver
an ultra-tight Micro-Inertial Measurement Unit (MIMU)/software receiver integration method is studi ed.The nonlinear tracking loop filter and integrated navigation filter are desig ned by analyzing the nonlinear characteristics of receiver tracking loop and MIM U.The performance of closed-loop ultra-tight integrated system is evaluated by experimental software receiver and Micro-Electro-Mechanical Systems (MEMS) in ertial data collected in real dynamic environments.The results show the improvem ent in the performance of the tracking loop in this ultra-tight aided configura tion under faintish In-phase/Quadra-phase conditions.
