Satellite Page
The GPS II
+
’s Satellite Page provides a visual reference of satellite acquisition and
position. As the receiver locks onto satellites, a signal strength bar will appear for
each satellite in view, with the appropriate satellite number (1-32) underneath 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 (Fig. 20a).
• Solid signal strength bars— the receiverhas 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 II
+
will then update your position, track, and speed
by selecting and using the best satellites in view. You can also access the GPS II
+
’s
contrast feature from this page (see p. 75).

1. Press the rocker keypad, adjust the level of contrast (Fig. 20b), and press ENTER.
