Study on Rate Fiber Optic Gyroscope North-finder Slope Compensating Arithmetic
速率光纤陀螺寻北仪倾斜补偿算法研究

A slope compensating arithmetic is proposed for a rate fiber optic gyroscope north-finder (FOGNF).The integral glide filter and least-squares technologies are adopted to deal with original measuring signal of fiber optic gyroscope and accelerometer.Experimental data shows that the problem,which north-find precision is influenced by slope angle,is solved.Simultaneously,the possible factors which are used to improve the precision of FOGNF are given.
