18-5 Installation: GPS antenna
Selecting an antenna
Fit one of these GPS antennas:
• Normally use the GPS antenna supplied.
• An optional differential beacon DGPS
antenna to give enhanced accuracy within
range of land based differential beacons
in areas where WAAS or EGNOS are not
available. Such a DGPS antenna has both a
GPS receiver and a beacon receiver, and it
automatically applies the beacon correction
to the GPS position.
• A compatible GPS or DGPS instrument or
antenna connected by NavBus (see section
18-10) or NMEA (see section 18-11). In this
case, the Explorer does not need its own
antenna.
Note:
• The Explorer can apply the WAAS and EGNOS
DGPS correntions to any GPS antenna.
• To configure the Explorer for different
antenna options, see section 17-4.
For more information, contact your Northstar
dealer.
To set the DGPS options of NONE or
WAAS/EGNOS:
Remove the Y cable (if connected) and connect
the GPS directly to the yellow input. Set the
option. See section 17-4. the new setting will be
displayed if it was successfully applied.
