采用旋转调制技术，研究了以动调陀螺为角速率传感器的全姿态寻北仪。为了控制有色噪声对动态寻北的影响，利用观测残差建立了有色噪声的AR模型，对有色噪声进行了拟合与预报，并利用改正后的观测信息、基于抗差估计原理构造了高崩溃污染率的初值辅以IGGⅢ方案迭代解算的混合算法。计算结果表明：采用AR模型对有色噪声进行拟合与预报，能够有效控制有色噪声的影响，并提高动态寻北的精度和可靠性。
本文讨论时间序列数据中异常值探测的Bayes方法。该方法针对AR模型引入不同类型的识别变量，通过比较这些识别变量的后验概率值与事先给定的阈值来进行异常值定位；基于Gibbs抽样算法，提出了识别变量后验概率值的计算方法和异常值的估算方法；进行了大量的试验和应用，证明了该方法对于解决时间序列数据中在同一时刻或不同时刻出现加性异常值或革新异常值的探测问题，是可行的和有效的。
