摘　　要：本文给出一种以DPS为核心的SINS/GPS组合导航系统设计,完成了硬件电路的设计,包括惯性传感器件的选取及电路各个模块的设计;实现了软件算法,采用了工程上实用的四元数捷联导航系统的算法。本系统用DSP替代传统使用的微处理器作为捷联惯导系统的核心处理器,可以减小系统的体积和成本,提高其性能价格比,使系统具备更好的应用价值和市场前景。This paper gives the design of SINS/GPS integrated navigation system based on digital signal processor （DSP）. The work of the paper can be divided into two parts： Firstly, the hardware design has been presented,including the choice of the sensor and the circuit design. Secondly, the software design has been finished, in which it adopts practical quaternion algorithm of strap-down iner- tial navigation system. We use DSP to replace formal microprocessor as center processor in this system and get higher performance and lower price. It has practical application in the field of navigation.
