To improve accuracy and increase your chances of a successful calculation, do the following while your phone is determining your approximate location: ⅷ Stay in the open. The GPS feature works best where there is nothing between your phone and a large amount of open sky. If possible, go outside, away from tall buildings and foliage. While performance in a building is improved by moving closer to windows, glass with certain sun shielding films may block satellite signals. ⅷ Hold your phone to enhance reception. Signals from GPS satellites are transmitted to your GPS antenna, which is in your phone antenna. Hold your phone away from your body, giving the antenna clear access to satellite signals. Do not cover the antenna area with your fingers or anything else. ⅷ Stand still. If possible, stand still until your phone is finished determining your location. Moving your phone at a walking pace while your phone is calculating your approximate location may substantially decrease GPS performance. ⅷ In a car. When using the GPS Enabled feature in a car, position your phone so that the GPS antenna has good access to GPS signals through the car's windows. Typically, the GPS antenna has best access to GPS signals in a car when placed near a window. Note Although moving your phone at a walking pace decreases GPS performance, moving it at the speed of a moving car does not. ⅷ Stay in network coverage. The network will provide your phone with information that helps determine your location more quickly and accurately. Updating Satellite Almanac Data Another way to keep the GPS feature of your phone working well is to keep your satellite almanac data up to date. The United States government maintains an almanac of data about where GPS satellites are as they orbit the Earth. This information is available to your phone. Keeping your satellite almanac up to date helps your phone determine your location more quickly. 126 Section 2F. Tools
