9ReferenceReceiver StatusReceiver Status is indicated at the top of the Satellite Status Page, directly above thesky view. The status will be shown as one of the following conditions:Searching for Satellites—the GPS V is looking for any available satellites in view.Locating Satellites—the GPS V is initializing and collecting new almanac data.This process can take up to five minutes, depending on the satellites currently in view.Acquiring Satellites—the GPS V is collecting data from available satellites, but hasnot collected enough data to calculate a position fix.2D GPS Location—at least three satellites have been locked onto and a 2-dimen-sional position fi x (latitude and longitude) is being calculated. ‘2D Differential’ willappear when you are receiving differential corrections in 2D mode.3D GPS Location—at least four satellites have been locked onto, and your posi-tion is now being calculated in latitude, longitude and altitude. ‘3D Differential’ willappear when you are receiving differential corrections in 3D mode.Lost Satellite Reception—the receiver is not tracking enough satellites for a 2Dor 3D fi x. This is likely due to obstruction of the antenna or limited coverage ofsatellites overhead.Not Usable—the receiver is unusable, possibly due to incorrect initialization orabnormal satellite conditions. Turn the unit off and back on to reset the unit.Simulating GPS Reception—the unit is in simulator mode and is not receivingsatellite information.When ‘2D Navigation’ or ‘3D Navigation’ is displayed, the position accuracy appearsdirectly below the receiver status. Position accuracy is expressed in feet or meters andrefl ects an estimated error in your current latitude/longitude position reading.Satellite Status Page‘Searching for Satellites’ may appear whenthe GPS V is first used. This indicates theGPS V is looking for any available satellite,then must update satellite almanac data.‘Simulating GPS’ means the GPS V is NOTlooking for satellites. Use the simulator modeto simulate operation when learning to usethe unit, or to save battery power when usingthe GPS V to plan a trip or change unitsettings.
