This is done in order to conserve battery life in your phone, which is often performing many other functions at the same time that it's tracking your run.Īnd that's the truth. Your GPS watch is continually getting data from the satellites, whereas your phone only gets periodic position updates which are then averaged out. It's that additional relay from tower or hot-spot to the sensor in your device that partly accounts for the inaccuracy. ![]() That's why it can take minutes for your watch to locate satellites and get a location lock, while smartphones tell you exactly where you are instantaneously-the towers and hot-spots they connect to are fixed positions that continuously receive data from the satellites above. In contrast, a smartphone's GPS sensor receives data that has been collected from nearby cell phone towers and/or Wi-Fi hot spots (known as Assisted-GPS, or A-GPS). True GPS devices, like the ones in airplanes, your car's navigation system, or in your Garmin Forerunner watch receive location data directly from satellites orbiting the earth. While the signals from space are the same, the way different devices receive and process them is where the potential for inaccuracy lies. You would think that a GPS signal is a GPS signal. ![]()
