摘　　要：简单介绍了基于光纤陀螺的捷联惯导系统的设计,相对于平台惯导系统捷联系统有很多优点,硬件简单,便于安装、维修和维护,大大降低了系统的成本,但捷联算法运算量大,因此用运算速度高的DSP作为解算单元,可以满足要求.给出了捷联惯导系统的数学模型以及方框图,重点介绍了系统的软件实现,给出了流程图.所有这一切已应用于实践,结果证明这一设计切实可行.The research of SINS based on DSP was introduced briefly in this paper.Compared with PINS, the SINS has many advantages, such as simple hardware, easy to use and maintain, there by reducing the cost . But it has large number of operation ,so DSP is used to meet the demand. The maths-model and the block diagram of the SINS were given. The emphasis was put on the realization of the software.The program and its flowchart were given. All this has been put into effect and the result shows that the research is applicable.
