摘　　要：无陀螺捷联惯导系统与北斗二号卫星定位系统优势互补,组合导航具有一定的工程应用价值.首先设计了一种九加速度计配置方案,基于矢量力学理论,推导了角速度变化方程,利用智能加权和曲线拟合方法给出了其计算方程,并推导了系统误差方程,然后建立了组合导航系统状态方程和观测方程,应用Kalman滤波技术完成了系统参数解算.仿真结果表明,组合导航系统具有精度高、成本低、可靠性好的特点.Gyroscope Free Strap- down Inertial Navigation System（GFSINS） and COMPASS -M1 navigation sys- tem own different advantages which complement each other, and the integrated system of them owns some applied value in engineering. A nine - accelerator allocation scheme is designed and the formulas of angular velocity are deduced based on principle of vector mechanics. The calculating equations are given out by use of intelligent weighted idea and curve fitting method, and also its error equations are deduced. Then Kalman filter is employed to calculate the key parameters after building the station and observation equations. The simulation result shows that the integrated system shows beautiful feature of high - precision, low - cost and good - reliability
