| 摘 要： | GPS姿态确定的精度不仅与单历元基线解算精度有关,还受基线长度和天线布设结构的影响。探讨了GPS姿态测量系统中基线长度和天线布设结构与姿态测量精度的关系。仿真结果表明:增加航向基线长度,能够提高航向角和俯仰角的精度,增加横向基线长度,能提高横滚角的精度;当基线长度一定时,将两基线正交布设,横滚角的精度最高。

| Abstract: | The accuracy of GPS attitude determination is related to the accuracy of baseline resolution and affected by the baseline length and the antenna layout structure.This paper discusses the relationship among the baseline length,the antenna layout structure and the accuracy of attitude determination in the GPS attitude determination system.Simulation calculation shows increasing heading baseline length can improve the accuracy of the course angle and the pitch angle,that increasing crosswise baseline length can improve the accuracy of the roll angle,and that the highest accuracy of the roll angle can be reached in the orthogonal layout of the two baselines when the baseline length is constant. |
