ACQUIRING SATELLITES

 When the receiver is in the process of acquiring enough satellite signals for

navigation, the receiver uses satellite orbital data (collected continuously from the

satellites) and last known position to determine the satellites that should be in view.

SATELLITE INFORMATION

Satellites currently in view are shown at their respective positions on a satellite

constellation diagram. The outer circle of the constellation diagram represents the

horizon, the inner circle represents 45° above the horizon, and the center point shows

thepositiondirectlyoverhead.Eachsatelliteisrepresentedbyasquarecontainingthe

Pseudo-Random Noise (PRN) number (i.e., satellite identiﬁcation number).

The INFO 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 PRN number (01-32 or 33-64 for WAAS) below each bar. The
