【摘要】 本文介绍了一种以DPS为核心的SINS／GPS组合导航系统设计,它具有体积小、成本低等优点。主要工作包括两个方面,一是硬件电路的设计,包括惯性传感器件的选取;二是软件的算法实现,对 SINS／GPS组合寻航算法进行研究,并对其数据处理算法——卡尔曼滤波算法作了进一步的仿真研究。结果证明,组合导航的精度相对于单纯捷联惯性导航系统有显著提高。更多还原

【Abstract】 This paper introduces the design of SINS/GPS integrated navigation system based on digital signal processor(DSP).The system has advantages of small volume and low cost. The work of the system can be divided into two parts: First, the hardware design, include the choice of the sensor. Second, the software design. This paper presents deep research of the Strap_down Inertial Navigation System(SINS) and the Global Positioning System(GPS) separately, and then discusses the SINS/GPS integrated navigation System. Due to its feasibility and convenience, Position-Velocity Integrated Kalman filer is selected as the filter algorithm used in the project and successfully implemented.更多还原
