Satellite Location

The location of each available satellite is displayed over two location rings.

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 will become highlighted on the loca-

tion rings. The unit can be set to display satellite location with North, or your

current track toward the top of the display.

Satellite Strength Indicator Bars

The Satellite Strength Indicator Bars not only show the strength of the signal

being received, they also show the status of the signal. The bars will be either

shaded with a light grey, or ﬁlled with solid black. If the bar is grey, it means

that the GPS is receiving a signal from the satellite and is in the process of storing

orbital data provided in the GPS signal. When the bar turns solid black, the GPS

is using the satellite signal for navigation. A “D” in or above the bar means that

differential corrections are being applied to that satellite.

Date, Time and Current Location

The GPS gets date and time information from the satellites. The satellites

are equipped with an atomic clock that is very accurate. Since the GPS clock is

derived from timing information sent from the satellite, the GPS clock is also very

accurate.

When the GPS receiver has achieved a 2D or 3D GPS Location, the current

location will be displayed in the selected Location Format.
