System Overview 1.8 ACCESSING THE INFORMATION (INFO) PAGE System Overview Flight Instruments EIS CNS Interface GPS Navigation Flight Planning Hazard Avoidance NOTE: Refer to Section 10.2 for the INFO Page System Status Messages. NOTE: A System Status Message and the word 'External' appearing next to the GPS Status indicates that the display connected to the GPS antenna is unavailable and the remaining display(s) are using the external GPS navigator for 2D GPS position data. In this case, the data collected from the external navigator is not considered a sufficient source of GPS data by the GSU 73 AHRS. VIEWING GPS RECEIVER STATUS Internal system checking is performed to ensure the GPS receiver is providing accurate data to the GDU(s). The G3X GDUs can be configured to share GPS information (refer to the G3X Installation Manual for configuration information). For example, a GDU can be configured to share its GPS position, velocity, and time data with another GDU. If a GDU is not using its own GPS receiver, the name of the GDU providing the data (i.e., '3D GPS Location (PFD)' or '3D GPS Location (MFD)') is displayed following the GPS Status text on the INFO Page. The GPS Status will display one of the following conditions: • Autolocate-Receiver is looking for any satellite whose almanac has been collected, which can take up to 5 minutes • Searching the Sky-Receiver is looking for satellites • Acquiring Satellites-Receiver is looking for and collecting data from satellites visible at its last known or initialized location, but has not acquired a fix • 2D GPS Location-At least three satellites have been acquired and a twodimensional location fix has been calculated. "2D Differential" appears when you are receiving DGPS corrections in 2D mode • 3D GPS Location-At least four satellites have been acquired and a threedimensional fix has been calculated. "3D Differential" appears when you are receiving DGPS corrections in 3D mode 190-01115-00 Rev. F Garmin G3X Pilot's Guide 39 Additional Features Integrated Autopilot Annun/Alerts Appendix Index

ACCESSING THE INFORMATION (INFO) PAGE
NOTE:
Refer to Section 10.2 for the INFO Page System Status Messages.
NOTE:
A System Status Message and the word ‘External’ appearing next to the GPS
Status indicates that
the display connected to the GPS antenna is unavailable
and the remaining display(s) are using the external GPS navigator for 2D GPS
position data.
In this case, the data collected from the external navigator is
not considered a sufficient source of GPS data by the GSU 73 AHRS.
VIEWING GPS RECEIVER STATUS
Internal system checking is performed to ensure the GPS receiver is providing
accurate data to the GDU(s).
The G3X GDUs can be configured to share GPS information (refer to the G3X
Installation Manual for configuration information).
For example, a GDU can be
configured to share its GPS position, velocity, and time data with another GDU.
If a
GDU is not using its own GPS receiver, the name of the GDU providing the data (i.e.,
‘3D GPS Location (PFD)’ or ‘3D GPS Location (MFD)’) is displayed following the GPS
Status text on the INFO Page.
The GPS Status will display one of the following conditions:
• Autolocate—Receiver is looking for any satellite whose almanac has been
collected, which can take up to 5 minutes
• Searching the Sky—Receiver is looking for satellites
• Acquiring Satellites—Receiver is looking for and collecting data from satellites
visible at its last known or initialized location, but has not acquired a fix
• 2D GPS Location—At least three satellites have been acquired and a two-
dimensional location fix has been calculated.
“2D Differential” appears when
you are receiving DGPS corrections in 2D mode
• 3D GPS Location—At least four satellites have been acquired and a three-
dimensional fix has been calculated.
“3D Differential” appears when you are
receiving DGPS corrections in 3D mode
