An unmanned airship was used to overcome the limitations of conventional aeromagnetic exploration systems. The airship was fabricated from non-magnetic fibre-reinforced plastic and urethane cloth, and filled with helium. The maximum payload is 10 kg and the flight time (with all equipment installed) is approximately 1 h. The airship is simple to move and store prior to gas injection, and easy to handle in the field because of its small size. An automatic flight algorithm enables stable and efficient exploration. A radiofrequency modem and long-term evolution router connect the airship to ground control even when it is not in the line of sight. Magnetic data and airship location are monitored in real time and verified using a helicopter. The airship showed high efficiency.

无人驾驶飞艇被用来克服传统航磁探测系统的局限性。飞艇由非磁性纤维增强塑料和聚氨酯布制成，并充满氦气。最大有效载荷为 10 公斤，飞行时间（安装所有设备）约为 1 小时。该飞艇在注气前易于移动和存放，并且由于其体积小而易于在现场操作。自动飞行算法可实现稳定高效的探索。射频调制解调器和长期进化路由器将飞艇连接到地面控制，即使它不在视线范围内。实时监控磁数据和飞艇位置，并使用直升机进行验证。飞艇显示出高效率。
