The GPS III’s Satellite Status Page provides a visual reference of various receiver

functions, including current satellite coverage, receiver operating mode, battery level

and position accuracy. As the receiver locks onto satellites, a signal strength bar will

appear for each satellite in view, with the appropriate satellite number (01-32) under-

neath each bar. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Hollow signal strength bars— the receiver has found the satellite(s) and is

collecting data.

• Solid signal strength bars— the receiver has collected the necessary data and

the satellite(s) is ready for use.

Each satellite has a 30-second data transmission that must be collected (hollow bar

status) before that satellite may be used for navigation (solid bar status). Once a fix has

been calculated, the GPS III will then update your position, track, and speed by select-

ing and using the best satellites in view. You can also access the GPS III’s contrast fea-

ture from this page.

To adjust the screen contrast:

1. Press LEFT or RIGHT on the rocker keypad to adjust the level of contrast, and press

ENTER to save the new contrast setting.

Sky View and Signal Strength Bars

The sky view and signal strength bars give you an indication of what satellites are

visible to the receiver, whether or not they are being used to calculate a position fix,

and the signal quality. The satellite sky view shows a bird’s-eye view of the position of

each available satellite relative to the unit’s last known position. The outer circle rep-

resents the horizon (north up); the inner circle 45º above the horizon; and the center

point directly overhead.

The Satellite Status Page

shows where the satellites are

and how strong the signal is

from each one. A solid signal

bar means the satellite is

ready to use.

Use the LEFT/RIGHT keys on

the rocker keypad to adjust

the screen contrast. Press

ENTER to save the setting.
