Satellite Information

Satellite Sky View
Satellite Location
The location of each available satellite shows over two location
rings on the Satellite Information Page. The outer ring represents
the horizon, the inner ring represents 45° above the horizon, and
the center represents directly overhead. When the unit is using a
satellite for navigation, the satellite number is highlighted on the
location rings. The unit can be set to show satellite location with
North or your current track at the top of the screen.

Satellite Strength Indicator Bars
The Satellite Strength Indicator Bars show the strength of the
signal being received, and the status of the signal. The bars are
either shaded or filled. The gray bar means the GPS is in the
process of storing orbital data it is receiving from the satellite
signal. When the bar turns solid, the GPS is using the satellite
signal for navigation. A "D" in or above the bar means that
differential corrections (WAAS or DGPS) are being applied to that
satellite.
Date, Time, and Current Location
The GPS gets date and time information from the satellite's on-
board atomic clock. When the GPS receiver has achieved a 2D
or 3D GPS location, the current location appears in the selected
location format.
