If the unit has not been in operation for more than six months, acquiring
satellite data to establish almanac and satellite orbit information may take
5 to 10 minutes.
A graph shows GPS signal strength for
up to 15 satellites. As the GPS receiver
locks onto satellites, a signal strength
bar appears for each satellite in view.
Graph symbols depict the progress of
satellite acquisition. Some data may not
display until the unit has acquired
enough satellites for a fix.
Receiver is searching for the indicated satellites.
Satellite located.
Satellite located, receiver is collecting data.
Data collected, but satellite is excluded from position
solution (i.e., it is not in use).
Satellite located, but FDE excludes it for being a faulty
satellite.
Data collected, but receiver is not using satellite in the
position solution.
Data collected, satellite in use in the current position
solution.
Differential corrections are in use (e.g., WAAS).
