GPS SIGNAL STRENGTH
The GPS Status Page can be helpful in troubleshooting weak (or missing) signal levels due to poor
satellite coverage or installation problems. As the GPS receiver locks onto satellites, a signal strength bar
is displayed for each satellite in view, with the appropriate satellite number (01-32) below 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 satellites and is collecting data
• Solid signal strength bars - the receiver has collected the necessary data and the satellites are ready for
use
• Checkered signal strength bars - the receiver has excluded the satellite (Fault Detection and Exclusion)
Selecting the GPS receiver for which data is displayed:
1) Select the GPS Status Page.
2) Press the
GPS1
Softkey for the display of information pertaining to GPS1 or press the
GPS2
Softkey for the
display of information pertaining to GPS2.
