Design on Strap-down Inertial Navigation System Based on DSP

Strap-down inertial navigation system(SINS) is an advanced technology and the one of the main developing trends of the inertial technology.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.
