It provides true north azimuth information to f all kinds of ground-based equipment. This paper designed a dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG). In this scheme  the sine output signal of the FOG was sampled and disposed  and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the base tilt was compensated by an accelerator. The output signals of FOG and accelerator were computed combined with the position sampled from increasing encoder by digital signal processor. Successive rotating technique was adopted to modulate the FOG signal periodically. Most of the low frequency part of random gyro drift errors was compensated. The north-finder accuracy was improved compared with the traditional static measuring method. The test result shows the FOG automatic north-finder obtains 2' true north angle accuracies within not more than three minutes  can meet the orientation need of artillery  terrain measurement vehicle  armored car  unmanned drive vehicle  geodetic survey and tunnel exploration.   Analytical study of dynamic aperture for storage ring by using successive linearization method 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2004, 卷号: 28, 期号: 1, 页码: 82-87 作者:  Yang, JC;  Xia, JW;  Wu, JX;  Xia, GX;  Liu, W   |  收藏  |  浏览/下载：22/0  |  提交时间：2010/10/29 Non-linear Betatron Oscillation  Successive Linearization  Dynamic Aperture
