Receiver Status and Accuracy

The receiver status is shown in the Status field on the Info sub tab. Current
accuracy is shown in the EPE (Estimated Position Error) field. Accuracy uses
many factors to calculate location accuracy in feet or meters including the number
of received GPS satellites, signal strength, and satellite orientation. 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 have
been acquired, and your location is now being calculated in latitude and
longitude; or at least four satellites have been 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 2-D or 3-D, 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 3005C is now ready for use. Press QUIT to return to the
Map Page.

Setup Sub Tab
The GPS Setup 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. See page
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.
