Receiver Status and EPEReceiver status is indicated at the top left of thescreen, with the current horizontal accuracy (estimatedposition error, in feet or meters) at the top right. Thestatus will show one of the following conditions:Searching— the GPS 125 Sounder is looking forany available satellites in view.AutoLocate TM— the GPS 125 Sounder is initializ-ing and collecting new almanac data. This processcan take 7.5 to 15 minutes.Acquiring— the receiver is collecting data fromavailable satellites, but has not collected enoughdata to calculate a 2D fix.2D Nav (2D Navigation)–– at least three satelliteswith good geometry have been locked onto and a2-dimensional position fix (latitude and longitude)is being calculated. ‘2D Diff’ will appear when youare receiving DGPS corrections in 2D mode.3D Nav (3D Navigation)— at least four satelliteswith good geometry have been locked onto, andyour position is now being calculated in latitude,longitude and altitude. ‘3D Diff’ will appear whenyou are receiving DGPS corrections in 3D mode.Poor Cvrg (Poor GPS Coverage)— the receiver isno longer tracking enough satellites for a 2D or 3Dfix.Not Usable— the receiver is unusable, possiblydue to incorrect initialization or abnormal satelliteconditions. Turn the unit off and back on to reset.SIM (Simulating Navigation)— the receiver is insimulator mode.EZinit Option PromptThe Satellite Page also provides access to the EZinitprompt whenever a position fix has not been calculated(the unit must be in searching, AutoLocate, acquiring,simulator or poor coverage status). This allows you tomanually reinitialize the unit (see pg. 6-7 for instruc-tions), and is useful if you have traveled over 500 mileswith the receiver off and you know it must be initial-ized to your new position (the GPS 125 Sounder willautomatically offer the EZinit prompt after 10 minutesof unsuccessful satellite acquisition). 19A ‘POOR CVRG’ statuswill appear on the SatellitePage if the receiver has lostthe satellites required tocompute a fix. Make surethe external antenna is notcovered and is connected tothe GPS 125 Sounder.REFERENCEReceiver Status& EZinitIf you travel more than 500miles with the receiver off,reinitialize the unit to yournew position by using theEZinit feature.
