The SINS of FOG is designed and implemented based on DSP. The system is with a dual CPU structure. DSP is used to process data while MCU controls data acquisition and the communication between DSP and MCU is achieved by dual-port RAM. All of these constitute a small strap-down navigation system. Meanwhile introduced a kind of algorithm of SINS, SPI communication and the second boot Loder of TMS320C6713 in briefly. After testing, the system speed and accuracy satisfy design requirements and the system has been applied to actual system.

I will introduce a method to solve this problem when data come from some common life distribution, such as Weibull distribution and Lognormal distribution. In chapter 1, we introduce background of grouped data and how to analyze them with classical methods. In chapter 2, we introduce EM algorithm and show that the estimation of the parameters get through this algorithm is convergent under certain conditions. In chapter 3, we use EM algorithm to estimate parameters in Weibull distribution and Lognormal distribution by grouped data and the simulation shows this method is available.
