Northstar Explorer 538i/538 Installation and Operation Manual 53
Selecting an antenna
Fit one of these GPS antennas:
• Normally use the internal GPS antenna
(Explorer 538i) or the GPS antenna supplied
(Explorer 538).
• 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
15-8) or NMEA (see section 15-9). In this case,
the Explorer 538/538i does not need its own
antenna.
Note:
• The Explorer 538/538i can apply the WAAS
and EGNOS DGPS correntions to any GPS
antenna.
• To configure the Explorer 538/538i for
different antenna options, see section 14-3.
For more information, contact your Northstar
dealer.
