6 GPSMAP 2106/2110 Owner’s Manual
GETTING STARTED > INITIALIZING THE GPS RECEIVER
Receiver Status and Accuracy
The Status field on the Info sub tab shows the receiver status. Current accuracy
is shown in the EPE (Estimated Position Error) field. Accuracy uses the number
of received GPS satellites, signal strength, and satellite orientation, to calculate
location accuracy in feet or meters. The Status field shows one of the following
conditions:
• Searching for Satellites—the receiver is looking for any satellites and
collecting data from satellites visible at its last known or initialized
location, but has not collected enough data to calculate a fix. This process
can take up to five minutes.
• Ready For Navigation—at least three satellites with good geometry
were acquired, and your location is now being calculated in latitude
and longitude; or at least four satellites were acquired and your location
is being calculated in latitude, longitude, and elevation. “Ready For
Navigation with WAAS” appears when you are receiving WAAS satellite
corrections in 2D or 3D, and a D appears on the strength bar of satellites
being corrected.
After the receiver has collected information from at least three satellites, the
Status field shows either “Ready for Navigation” or “Ready for Navigation with
WAAS.” The GPSMAP 2106/2110 is now ready for use. Press QUIT to return to
the Map Page.
GPS Setup
The Setup sub tab provides access to functions and features relating to initializing
the GPS receiver.
To access the GPS Setup sub tab:
1. Press and hold ADJ/MENU to open the Main Menu.
2. Highlight the GPS tab, and then highlight the Setup sub tab.
Setup Sub Tab
The Setup sub tab contains the following options:
Skyview Orientation—allows you to select a sky view orientation, either North
Up or Track Up, for the GPS Info sub tab only.
Source
—set to Garmin when using a Garmin sensor (GPS 17); set to NMEA
when using any other GPS NMEA source.
WAAS—turns WAAS on or off.
The following soft keys are active only when the unit is not receiving satellites
and the Source is not set to Garmin:
• AutoLocate—allows the receiver to find your location automatically. This
process can take up to five minutes.
• Set Position—allows you to initialize the receiver from the Map Page to
initially help the receiver acquire satellites more quickly.
