cf Que™ 1620 GPS Applications GPS Info Acquiring Satellites 2 Dimension Position Location 3 Dimension Position Location Understanding the GPS Info Page The GPS Receiver must determine its location on the earth by receiving signals from overhead satellites each time it is turned on. The GPS Info Page displays the current status of the GPS receiver. To view the GPS Info Page: 1. Tap Start to display the main menu, tap Programs and then Garmin Que to display the Map Page. 2. Tap Menu on the menu bar at the bottom of the page and then select GPS Info to display the Satellite Status Page. At the top of the Satellite Status Page is a message containing the status of the GPS receiver and a sky view array on the left side representing the position of satellites in the sky overhead with your position in the center of the two circles. The outer circle indicates the horizon while the inner circle a position 45o from the horizon. The numbers displayed indicate the number assigned to those satellites. A bar graph at the bottom of the page displays the strength of signals being received from each satellite. An "Acquiring Satellites" message is displayed until at least three satellites with sufficient signal strength have been received. When the GPS receiver has determined its location, a "2D" message appears and your location coordinates display at the top of the left hand column. On the right, the date and time displays along with your approximate elevation, and, if you are moving, your current speed displays as well. When you have sufficient signals from four or more satellites, a "3D GPS Location" message appears and the approximate elevation also displays at the bottom of the column. The accuracy of your current position displays at the bottom of the list. All of this information continues to update as you navigate. Establishing an initial location When starting up for the first time, or when you have moved to a new location more than 600 miles from the last one, it will take some time for the cf Que to determine its new location. To facilitate the initialization process : 1. Tap Menu tab at the bottom of the page to display the "New Location" and "North Up" or "Track Up" options. 2. Tap New Location if you want to go to the Map Page and mark your approximate location to help the satellite narrow its search for satellites. Using its built-in almanac of satellite positions, the cf Que looks for signals from only those satellites that are in sight at that location. The Options Menu also allows you to orient the sky view graphic to "North" or to "Track" in the direction of your movements. Main Menu Location Option -20-
