GPSMAP 496 Owner's Manual 3 GETTING STARTED > GETTING SATELLITE SIGNALS Getting Satellite Signals After you turn on the GPSMAP 496, the unit automatically begins searching for satellites. The GPS Page appears while the unit is gathering satellite signals and acquiring a fix. This process should take only a few minutes. While the GPSMAP 496 is getting satellite signals, the GPS Page shows the status as "Acquiring Satellites." It can take a few minutes to acquire satellites and show your current location on the map. Be patient as the unit acquires satellite data. To get signals more quickly, be sure the antenna is raised to the up position shown in the image on page 1. Viewing GPS Status With the GPS Tab The GPS tab provides a visual reference of satellite acquisition, receiver status, and accuracy. The sky view and signal strength bars give an indication of what satellites are visible to the receiver and whether they are being tracked. As the receiver locks onto satellites, a signal strength bar appears for each satellite in view, with the appropriate satellite number underneath each bar. The numbers shown below each bar represent the particular satellite that is being received. Numbers above 33 indicate WAAS satellites. The sky view shows a birds-eye view of the location of each satellite relative to the receiver's last known location. The outer circle represents the horizon (north up), the inner circle represents 45º above the horizon, and the center point represents a location directly overhead. You can also set the sky view to a Track Up configuration, causing the top of the sky view to align along your current track heading. GPS Page NOTE: While acquiring satellites, the Map Page can show the wrong location, such as China. This does not mean your unit has the wrong data loaded. The GPS receiver needs a few more minutes to acquire satellites and find your current location. 4 A power source indicator shows the unit is operating off battery power ( ), that the unit is charging ( ), or that an external power source is in use ( ). GPSMAP 496 Owner's Manual GETTING STARTED > GETTING SATELLITE SIGNALS Signal strength bars Receiver status field Receiver Status Sky view Power source indicator GPS Page The progress of satellite acquisition is shown in three stages: · No signal strength bars--the receiver is looking for the satellites indicated. · White signal strength bars--the receiver has found the satellite and is collecting data. · Green signal strength bars--the receiver has collected the necessary data from this satellite. As soon as the GPSMAP 496 has collected the necessary data from the best satellites in view to calculate a fix, the status field indicates the status of the receiver. The unit then updates the location, date, and time. The Receiver Status field shows one of the following conditions: · Searching the Sky--the receiver is looking for satellites. · AutoLocate--the receiver is looking for any satellite whose almanac has been collected, which can take up to 5 minutes. · Acquiring Satellites--the receiver is looking for and collecting data from satellites visible at its last known or initialized location, but has not acquired a fix. · 2D GPS Location--At least three satellites have been acquired and a two-dimensional location fix has been calculated. "2D Differential" appears when you are receiving DGPS corrections in 2D mode and a "D" appears on the strength bar of satellites being corrected. · 3D GPS Location--At least four satellites have been acquired and a three-dimensional fix has been calculated. "3D Differential" appears when you are receiving DGPS corrections in 3D mode and a "D" appears on the strength bar of satellites being corrected. · Lost Satellite Reception--the receiver is no longer tracking enough satellites for a 2D or 3D fix. · Receiver Not Usable--the receiver is unusable, possibly due to interference or abnormal satellite conditions. Turn the unit off and back on to reset. · Simulating GPS--the receiver is in Simulator Mode. · GPS Off--the GPS receiver is turned off. 5 GPSMAP 496 Owner's Manual GETTING STARTED > GETTING SATELLITE SIGNALS GPS Tab Options Press MENU two times to open the Main Menu.
