摘要
介绍了一种低空无人机磁场测量系统,系统利用无人驾驶飞行器搭载三分量磁通门磁力仪,采用硬连接支架垂吊,在中高山地区进行作业,具有成本低、较高精度、安装简单、低空作业安全系数高等优点。同时,就噪声测试、距离测试、质量控制、操作规范等几个方面进行了阐述。如何进一步降低该系统的噪声水平(利用磁补偿等)、提高作业效率以及改进无人机搭载平台,是系统还待解决的问题。
An aeromagnetic survey system is presented in this paper. The unmanned aircraft is equipped with a threecomponent fluxgate sensor fixed by a carbon fiber rod to the aircraft. This system has advantages of low cost, easyinstallation and high safety coefficient etc. The methods for testing noise level, defining proper line distance, ensuring data quality and so on are put forward too. There are still some problems pressing for solutions such as how to turn down the noise using magnetic level further（by compensation）, how to improve the working performance and ameliorate the aircraft （increase flying time and the load）
