The Output Model of FOG North-Finding System Constructed by the ARMA Timing Analysis

This paper used the timing analysis to statistically analyze the output sequences of many FOGs which were using in the north-finding system. We confirm an optimal model basing the statistic characteristics, and finally advance a fixed algorithm to estimate the parameters of the model. The results show that the modeling method has the universality to the output data of FOGs in the north-finding system, and also can be used to get the precise parameters in order to serve the following filter.
