| 摘 要： | 对捷联惯性制导系统弹载计算机四元数计算的舍入误差进行了概率估计。首先建立定点计算机上四元数计算舍入误差的概率模型，然后利用该模型得到舍入误差的分布函数，进行舍入误差的概率分析。

| Abstract: | The round off errors are estimated for the quaternions recursive formula which is frequently used at present in the strapdown intertial guidance system First,the probabilistic model of the round off error in the computation of quaternions on a fixed point computer is established Then,the probabilistic round off error estimates are computed |
