摘　　要：笔者介绍了无人直升机航磁系统的研发与集成,采用无人直升机作为飞行平台,搭载高精度航空磁测系统,具有低成本、高效率、不受机场跑道限制、可夜航、按设计测线全自主导航飞行等特点。该系统分别完成了磁补偿试验飞行与实际应用工作,补偿精度达到0.046 9 n T,测量成果与测区内以往航磁成果对比,其反映的地磁场特征形态基本一致,验证了该系统的有效性,航磁异常等值线在细节上表现更细致。本系统为大比例尺、高精度、小面积的航磁测量工作提供了一种高效灵活的工作手段。This paper introduces the research, development and integration of an unmanned helicopter aeromagnetic survey system. The system uses an unmanned helicopter as flying platform to carry out the high-precision aeromagnetic equipment. As all know, the unmanned helicopter doesn't need a runway to take off and land, and has the ability to self-navigate according to designed lines and to work at night. Thus, it can get a higher efficiency at a lower costing. An aeromagnetic compensation flight whose accuracy was 0.046 9 nT and several survey flights have been accomplished. Compared with the previous aeromagnetic survey in the same area, the characteristics of the geomagnetic field are basically alike, which validates the effectiveness of the unmanned helicopter aeromagnetic system. The unmanned helicopter aeromagnetic anomaly map is more detailed because of the different parameters such as scale and instrumental accuracy and sampling rate between the two systems. This unmanned helicopter aeromagnetic survey system provides an effective and flexible means for large scale, high-precision and small area aeromagnetic survey.
