Travelling Need directions? Looking for a restaurant? Your Eseries device has the tools to get you where you want to be. About GPS and satellite signals The Global Positioning System (GPS) is a worldwide radio navigation system that includes 24 satellites and their ground stations that monitor the operation of the satellites. Your device has an internal GPS receiver. A GPS terminal receives low-power radio signals from the satellites and measures the travel time of the signals. From the travel time, the GPS receiver can calculate its location to the accuracy of metres. The Global Positioning System (GPS) is operated by the government of the United States, which is solely responsible for its accuracy and maintenance. The accuracy of location data can be affected by adjustments to GPS satellites made by the United States government and is subject to change with the United States Department of Defense civil GPS policy and the Federal Radionavigation Plan. Accuracy can also be affected by poor satellite geometry. Availability and quality of GPS signals may be affected by your location, buildings, natural obstacles, and weather conditions. GPS signals may not be available inside buildings or underground and may be impaired by materials such as concrete and metal. GPS should not be used for precise location measurement, and you should never rely solely on location data from the GPS receiver and cellular radio networks for positioning or navigation. The trip meter has limited accuracy, and rounding errors may occur. Accuracy can also be affected by availability and quality of GPS signals. To enable or disable different positioning methods, such as Bluetooth GPS, select Menu > Tools > Settings > General > Positioning > Positioning methods. About satellite signals If your device cannot find the satellite signal, consider the following: • If you are indoors, go outdoors to receive a better signal. • If the numeric keypad slide is closed, open it. • If you are outdoors, move to a more open space. • Ensure that your hand does not cover the GPS antenna of your device. • If the weather conditions are bad, the signal strength may be affected. • Establishing a GPS connection may take from a couple of seconds to several minutes. 84 © 2010 Nokia.
