摘　　要：对捷联式制导系统中目前常用的四元数递推公式进行误差估计，给出利用观测数据计算四元数的误差界的公式，还介绍了保持四元数范数不变的一类递推公式。The errors are estimated for the quaternions recursive formula which is frequently used at present in the strapdown navigation system The formulas are given,by which a bound of the errors in the quaternions can be computed in terms of the observation data Furthermore,a class of recursive formulas is also introduced,which may preserve the norm of quaternions
