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
progress of satellite acquisition is shown in three stages, as indicated by signal
bar appearance:
- No bar—Receiver is looking for the indicated satellite
- Gray bar—Receiver has collected the necessary data and the satellite signal
can be used
- Green bar—Satellite is being used for the GPS solution
POSITION
The Position box on the
INFO
Page displays latitude, longitude, accuracy (in
feet), reference waypoint, type, distance, direction, and bearing. The reference
waypoint is designed to display the current position in relation to a prominent
landmark. The pilot can change the reference waypoint ‘Nearest Type’ using the
‘Change Nearest Type’ page menu option. By default the Nearest Type is set to
‘Automatic’, which will display the nearest large airport, enroute VOR, or city (in
that order).
