Why not equip a drone with a scanning radio receiver, fly that over the forest canopy in a certain pattern which would allow the user or the operator to triangulate the location of these radio-collared animals remotely without having to step foot in the forest.
为什么不给一架无人机 装备一个无线电接收装置， 让它在森林上空 以一个特定的路线飞行， 这样可以让操作者 用三角测量的方法确定 携带着无线电圈的动物的位置， 而完全不需要研究者进入森林。
