确定精密的随时间变化的方位是鉴定和维护惯性导航仪器的一个重要条件。现在,技术上的进步要求试验与鉴定精度小于1弧秒。这意味着地球物理和环境对方位基准时间稳定性的影响是很值得注意的。同样,也必须评定测试设备在试验中固有的方位运动。本文介绍美国新墨西哥州霍洛曼空军基地跟踪试验基准方位运动用的自动惯性方位测量系统。提出了该系统的详细误差分析和提高性能与精度的方法。讨论了改进现有方位测量技术所选择的途径。
Determining the precise position over time is an important condition for identifying and maintaining inertial navigation equipment. Now, the technical progress requires the accuracy of testing and identification is less than 1 arc second. This means that the impact of geophysics and environment on the stability of the azimuth reference time is noteworthy. Similarly, the inherent azimuthal motion of the test equipment during the test must also be assessed. This article describes the Automatic Inertial Azimuth Measurement System used by Holloman AFB, New Mexico, to track and test the reference azimuth motion. The detailed error analysis and the method to improve the performance and accuracy of the system are proposed. Discussed the ways to improve existing azimuth measurement techniques.
