| 摘 要： | 逆转点观测方法是陀螺经纬仪传统观测方法之一，并已被应用到高精度自动观测陀螺经纬仪中。运用动态数据处理方法，对逆转点观测数据进行分析，得出二阶自回归（ＡＲ）模型能够较好地描述逆转点观测数据中的随机干扰误差的影响，为自动观测陀螺经纬仪数据处理提供了理论依据。

| Abstract: | The mothod of reversal points is one of the most classical gyrotheodolite observation methods. Now, it has been used in some high precise auto-gyrotheodo-lites. In this paper, dynamic data processing method is applied to analysis reversal points measuments. It turn out that AR model better than others in expressing the ef-fection of random interfere error during reversal points measurments, which is useful in data processing of high psecise auto-gyrotheodolite. |
