GPS Information Page The GPS Information Page displays your speed, elevation, the estimated accuracy, receiver status, satellite locations, satellite signal strength, the date, time and the GPS receiver's current location. Speed, Elevation and Estimated Accuracy When the GPS is receiving at least three satellite signals, it will provide you with the current GPS Speed and the estimated Accuracy of the GPS Location. The GPS must be receiving at least four satellite signals to report the Elevation. Current GPS Receiver Status The current status of the GPS receiver will always be displayed. Autolocate - Forces the receiver to search for each satellite individually. Acquiring Satellites - The receiver will be in this mode when the unit is turned on. The receiver will remain in this mode until it has acquired at least 3 satellite signals. 2D GPS Location - Indicates that the receiver is only using three satellite signals. When a 2D GPS Location is achieved, the GPS will display your current position but is incapable of providing an altitude reading. 3D GPS Location - Indicates the receiver is currently using at least four satellite signals and is capable of providing your current position and altitude. 2D Differential Location - Indicates the receiver is using DGPS or WAAS differential data on three satellites. A "D" will be displayed in or above the indicator bar for each differentially corrected satellite. 3D Differential Location - Indicates the receiver is using DGPS or WAAS differential data on at least four satellites. A "D" will be displayed in or above the indicator bar for each differentially corrected satellite. Lost Satellite Reception - Indicates that the GPS receiver has lost satellite reception. Simulating GPS - Indicates the GPS 72 is running in Simulator Mode and the GPS receiver is turned off. It is important to remember when you are using the Simulator, the GPS 72 can not be used for actual navigation.
