基于状态转换的双天线定向软件的设计与验证

在高动态的导航定位定向的应用中，经常会遇到观测环境比较恶劣的情况。针对这种情况，本文详细分析了在不同的变星情况下模糊度空间的传递过程，并以此为基础设计了一种基于状态转换的双天线定向软件。用户可以时刻了解系统的运行状态，便于用户进行其他实时操作。通过理论推导和实测仿真数据分析表明，该软件能很好地适用于卫星频繁遮挡的情况，且实验效果良好，长度为3m的基线其航向角精度优于0.1°，俯仰角精度优于0.2°，具有一定的实用价值。

Design and Validation of Two-antenna Orientation Determination Software Based on State Switch Technique

When the user needs to determine its position and orientation in the high dynamic scene, he may often suffer from some bad observation surroundings.. In view of this situation, this paper analyses the transformation of the ambiguity space from one epoch to the next when the SV numbers change frequently , and designs a two-antenna orientation determination software based on the state switch technique. The running state of system can be known by users all the time. This just can fulfill the requirements of real-time operation. The Results of derivation and experimental simulation data analysis indicate that software designed here can fit the scenes that the satellites are frequently blocked sufficiently. If the length of baseline is 3m, the yaw accuracy is better than 0.1 deg, and the pitch accuracy is better than 0.2 deg.
