However, receiving the signal only tells you the direction of the animal's activity. You have to have two receivers getting a signal from the same bear simultaneously, and then you have to find the intersection of the directional lines on a map to determine the bear's position (this is called triangulation).
由於收到訊號時只知道動物的活動方位，必須兩人同時收到同一隻熊的訊號，透過地圖找出兩條方位線的交叉點，才能確認熊的位置（即三角定位法）。
