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 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 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 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 3006C/3010C 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.
