Quest Owner’s Manual 45U NDERSTANDING GPS > THE GPS INFORMATION PAGESatellite Status BarAs soon as the GPS receiver in your Quest has collected thenecessary data to calculate a fix, the status bar indicates a positionfix. The current GPS status and the accuracy of the position fix canbe found in the satellite status bar located at the top of the page.The status bar displays one of the following messages:Searching for Satellites—the GPS receiver is looking for anyavailable satellites in view.Locating Satellites—the GPS receiver is locating satellites anddetermining which ones are visible at your location.Acquiring Satellites—the GPS receiver is collecting data fromavailable satellites but has not collected enough data to calculate aposition fix.Satellite status barReady to Navigate—the Quest is ready to navigate routes.2D Navigation—at least three satellites with good geometry havebeen found; a two-dimensional position fix (latitude and longitude)is being calculated. You might need to enter your elevation if thereceiver only has a 2D fix. Displays “2D Differential” if you aretracking one of the WAAS satellites.3D Navigation—at least four satellites with good geometry havebeen found; your location is now being calculated in latitude,longitude, and elevation. Displays “3D Differential” if you aretracking one of the WAAS satellites.Lost Satellite Reception—the GPS receiver has temporarily lostsatellite reception.Poor GPS Coverage—the GPS receiver is not tracking enoughsatellites for a 2D or 3D fix due to bad satellite geometry or due toa shaded antenna, which can be caused from very dense overheadtress or tall buildings.Receiver Not Usable—the Quest is unusable, possibly due toincorrect initialization or abnormal satellite conditions. Turnthe unit off and back on to reset and re-initialize the receiver ifnecessary.GPS is Off—the GPS receiver has been turned off and cannot beused for navigation.
