These signals can be easily blocked by trees, buildings, an automobile roof, even your body. Like most GPS receivers, the unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the satel- lites to calculate a position. Speed, direction of travel, and distance are all calcula
