| 摘 要： | GPS姿态测量技术是根据安装在载体上的多天线阵所确定的基线平面来推算出载体的航向及姿态原理。通过将载体姿态信息反映在其多天线阵接收信号状态上,并形成测姿所用的观测文件,以实现对测姿接收机在各种环境条件下的灵活测试。提出了GPS姿态信号模拟的原理设计方案,同时进行了建模与仿真分析,包括从姿态信号生成模拟、多天线阵定位解算到载体姿态解算的一系列完整过程。仿真结果表明,三维姿态角标准差都在0.2°以下,符合实际情况。

| Abstract: | GPS attitude determination technology can calculate the attitude of carrier according to the basal plane from multi-antenna array on it.Through emulating the signal of multi-antenna array which can reflect its carrier’s attitude,and arranging these data to observe-files for attitude determination,the test on attitude determination receiver can be more easy and agile.The theory of the system is put forward,simulation and test under the circumstance of static and dynamic are performed.Simulation results show that the standard deviations of three-dimensional angles are below 0.2°,which accords well to the actual situation. |

| Keywords: | attitude signal simulator Global Positioning System muti-antenna array |
