多天线GPS测向在电力巡线无人机中的应用
首发时间:2017-06-09
摘要:无人机通常使用电子罗盘测向,然而在应用于电力巡线领域时,由于电力线路有强磁干扰,电子罗盘本身通过测量地球磁场来测向,线路的磁干扰会严重影响电子罗盘的测向结果,给无人机带来极大的安全隐患。GPS接收机可接收卫星的载波相位信息,通过双天线GPS的基线长度约束和载波相位信息,可精确解算出载体的姿态信息,且不受电力线路磁干扰。本文提出一种方案,通过双天线GPS的测向算法来给无人机提供精准的航向信息。仿真与实验结果表明,所提出的方案能够较好地实现无人机航向测量需求。

Direction determination in a power line inspection UAV Using Multi-Antenna GPS
Abstract:UAVs typically use electronic compass to provide heading information. However, when applied to the power line inspection, electronic compass detects direction by measuring the Earth's magnetic field, the measurement results can be seriously affect due to the magnetic interference of the power line. GPS receiver can receive carrier phase information ,so the attitude information of the carrier can accurately be calculated by baseline length constraint and dual-antenna GPS carrier phase information. In this paper, a Multi-antenna GPS direction determination algorithm is used to provide heading information for power line inspection UAV. The robustness and effectiveness of the proposed scheme have been validated experimentally
Keywords: UAV Multi-antenna GPS direction determination
