针对设计捷联惯性导航系统时系统指标要求合理选择惯性传感器的问题，提出一种捷联惯性导航系统误差分析方法，建立了系统在不同工作条件下的误差模型，给出了在设计捷联惯性导航系统时，纯惯性导航时间小于2 min、位置误差小于100 m时选择陀螺和加速度计的方法。

For choosing right gyro and accelerometer to design a good strapdown inertial navigation system(SINS) according to its precision need ,a new error analysis method combining theory with engineer design experience was proposed .The functions of inertial sensor‐error ,velocity‐position error and attitude error under difference working conditions of SINS were set up .One method that for designing a SINS with the position‐error less than 100 m during 2 min was suggested .
