舰艇航向标校基线方位角的精确测量方法研究

导航装备的航向参数直接关系到舰艇航行的安全和舰载作战武器系统的精确打击能力,标校该参数首先要建立高精度的测量基线。文章研究了利用天文测量技术实现舰艇航向标校基线方位角精确测量的方法,包括时角法、高度法、解析法、任意单星法等,每一种方法均满足舰艇航向标校基线方位角测量的精度要求,综合应用这些方法,可以在任意纬度、有无天文年历情况下实现标校基线方位角的高精度测量。

High Accuracy Determination of Azimuth of Baseline Used to Calibrate Ship's Heading Based on Astronomical Method

It is important to calibrate the heading parameter of navigation equipment and it has great influence on the sailing safety and the shipborne weapon system s ability of precision hitting.This paper briefly introduces the status and advantage of the celestial determination technology,mainly studies five directional methods based on astronomical,such as time method,height method,analytic method,random star method,etc.Each method contents with the precision of the baseline s azimuth.Integrating these five methods, we can accomplish the high accuracy determination at any latitude and with or without ephemeris.
