摘要

机械陀螺经纬仪初寻北时间的长短是决定其寻北效率的关键因素。从陀螺仪寻北的原理出发

在智能寻北系统中引入了一种快速寻北新方法加速度判定法。该方法通过计算光标运动的速度与加速度值

能够在陀螺开始寻北数秒后即测量出真北值

并且能够弥补电子罗盘初寻北精度过低的问题

是全自动寻北策略的重要组成部分。以JT-15陀螺仪为样机的寻北实验表明

将加速度判定法应用于智能寻北系统中

仪器初寻北测量精度优于3'54

满足了JT-15陀螺仪精寻北的条件要求

保证了全自动寻北的速度和精度

对于机械陀螺的快速及智能化寻北具有现实意义。

Abstract

The coarse north-seeking time of a mechanical gyro theodolite is an important factor to decide north-seeking efficiency. A quick coarse north-seeking method named curve fitting is brought into the intelligent gyro theodolite system in this paper. By the proposed method

the true north value can be obtained in 10 s after gyro operates through a counting cursor to calculate the movement velocity and acceleration

and it can also compensate the low precision caused by an electronic compass. The experiment using JT-15 gyro shows that the measurement precision is superior to 3'54 when seeking coarse north

which meets the precise north-seeking condition of the JT-15 gyroscope. The application of the curve fitting method to the auto north-seeking system can ensure the velocity and precision of north-seeking automatically

and also has realistic significance to improve the efficiency and automation for mechanical gyro theodolites.
