摘要
从工程应用角度,以光纤惯性组合测量系统位置误差相关项为观测变量建立系统观测模型。采用蒙特卡罗法对光纤陀螺组合测量系统SINS/缆长组合进行了仿真计算。仿真结果表明,在秒级缆长更新速率情况下,采用中等精度的光纤陀螺和加速度计,组合测量系统的姿态测量精度满足工程测量要求。方位角测量精度优于1°,倾斜角测量精度优于0.1°。
From the point of view of engineering application and taken position errors of FOG strapdown inertial integrated surveying system as observed variables,system error model is introduced.Based on Monte-Carlo method,the simulation of SINS/cable length integrated surveying system is studied.The simulation indicates that a good agreement and accuracy of measurement meet the requirement of engineering by using FOGS and accelerometers of medium precision under the condition of the cable length＇s second level renew.The accuracy of the azimuth measurement is less than 1°,and the accuracy of the measurement for inclination angle is less than 0.1°.
