Garmin GNS 430 Pilot's Manual & Reference page 53

Each satellite has a 30-second data transmission that must be collected (hollow signal
strength bar) before the satellite may be used for navigation (solid signal strength bar).
Once the GPS receiver has determined your position, the GNS 430 will indicate your
position, track and ground speed on the other navigation pages. The GPS receiver status
fi eld (see preceding page) will also display the following messages under the appropriate
conditions:
• Searching Sky— The GPS receiver is searching the sky for ANY visible satellites.
You will also be informed of this status with a "Searching the Sky"
message.
• Acquiring Sat— The GPS receiver is acquiring satellites for navigation. In this
mode, the receiver uses satellite orbital data (collected continu-
ously from the satellites) and last known position to determine
which satellites should be in view.
• 2D Navigation— The GPS receiver is in 2D navigation mode. Altitude data will be
provided by an altitude serializer.
• 3D Navigation— The GPS receiver is in 3D navigation mode and will compute alti-
tude using satellite data.
• Poor Coverg— The GPS receiver cannot acquire sufficient satellites for
navigation.
• Rcvr Not Usbl— The GPS receiver is unusable due to incorrect initialization or
abnormal satellite conditions. Turn the unit off and on again.
• AutoLocate— The GPS receiver is looking for any available satellite. This pro-
cess can take up to five minutes to determine a position.
