| 摘 要： | 研究的目的是将LEA-6T应用在UAVPM系统中,探讨不同速度对偏航距和定位精度(均方差)的影响。简要介绍了UAVPM系统结构,在此基础上详尽围绕I2 C硬件接口,数据提取,坐标转换等方面阐述LEA-6T与UAVPM系统集成。结合小型无人直升机做飞行实验,实验数据证明集成了LEA-6T的UAVPM做航磁磁测时,飞行速度保持在30km/h以内,满足预期偏航距不大于150m,定位精度(均方差)不大于10m的要求。

| Abstract: | The purpose of this study is to apply the LEA-6T to UAVPM system and to ex- plore the different speed of yaw and the influence of the positioning accuracy （mean square error）. The system structure of UAVPM is first briefly introduced. Based on this, the LEA-6 and UAVPM systems are detailedly described through itsI2C hardware interface, data extraction and coordinate conversion . By analyzing data collected from an experiment on a small unmanned helicopter . We find that the speed to keep within 30 km/h, meeting the expected drift away from the 150m or less, positioning accuracy （mean square error） 10m or less. |
