【摘要】 全球导航卫星系统(GNSS,Global Navigation Satellite System)与航位推算定位系统(DRPS,Dead Reckoning Positioning System)是陆地导航系统中的两种典型定位技术。本文采用GNSS中的全球定位系统(GPS,Globe Position System)和DRPS中的微型惯性导航系统(MINS,Micro Inertial Navigation System)研制完成基于DSP的GPS/MINS组合陆地导航系统硬件平台。GPS功能模块由专用集成芯片(ASIC,Application Specific Integrated Circuit)射频前端变频器和数字通道相关器构成GPS芯片组;MINS功能模块由集成微电子机械系统(iMEMS,integrated Micro Electro Mechanical Systems)技术的多轴运动惯性传感器构成三维微型捷联式惯性导航系统(MSINS,Micro Strapdown Inertial NavigationSystem);采用单片高速浮点型数字信号处理器(DSP,Digital Signal Processor)作为GPS/MINS组合导航数掘的处理平台;运用一片现场可编程逻辑门阵列(FPAG,FieldProgrammable Gate Array)设计的异步通用串行发送器(UART,Universal AsynchronousReceiver/Transmitter)将标准导航数据传输到带有RS232接口的外围应用设备上。从而实现全天候、无地界组合陆地导航。论文采用一般与具体的叙述方式,以五大集成模块及其外围辅助电路设计为主要内容;以完成各模块间接口连接进而实现整个系统硬件平台设计为根本目的,并在此基础上给出了GPS跟踪环路算法和MINS捷联导航算法。实践表明整个系统具备连续、可靠定位;具有成本低、体积小;适合中、高档陆地车载导航以及近地面空中导航。更多还原

【Abstract】 Global Navigation Satellite System (GNSS) and Dead Reckoning Positioning System (DRPS) are the two typical positioning technology of the land navigation. In this paper, Global Positioning System (GPS) in the GNSS and Micro Inertial Navigation System (MINS) in the DRPS are applied to develop the hardware platform of GPS/MINS Integrated Land Navigation System Based on DSP.GPS functional modules from a GPS chip set of Application Specific Integrated Circuit (ASIC) is made up of radio-frequency converter of front-end and digital channels correlator; MINS functional modules from more Axis inertial sensors of integrated Micro Electro Mechanical Systems (iMEMS) technology constitute a three-dimensional micro strapdown inertial navigation system (MSINS); Adopting a single highly floating-point Digital Signal Processor (DSP) act as processing platform of GPS/MINS integrated navigation data; Using a field programmable gate array (FPAG) design a Universal Serial asynchronous transmitter (UART) which transfer standard navigation data to the external application equipment with RS232 interfaces. To achieve all-weather, no land boundaries of integrated navigation.Papers used in general and specific narrative approach, to complete the five modules and design of externally integrated circuit for the main content; to implement the connection between each module interface then design of the entire system hardware platform as the fundamental purpose and on this basis given the GPS tracking loop algorithm and the MINS strapdown navigation algorithm. Practice shows that the entire system with continuous, reliable position; its low cost, small size, suitable for medium to high-end land-based vehicle navigation and air navigation near the ground.更多还原
