16-5 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
16-8) or NMEA (see section 16-9). In this case,
the 557/567 does not need its own antenna.
Note:
• To configure the 557/567 for different antenna
options, see section 16-5.
For more information, contact your Northstar dealer.
DGPS Source:
Enables or disables the satellite based DGPS
correction (see section 7). The options are None or
WAAS/EGNOS. Do not Enable WAAS/EGNOS
outside their coverage areas or the accuracy of the
position might be degraded.
WAAS covers all of the USA and most of Canada. To
use WAAS, the GPS antenna must have a clear view
of the sky towards the equator. EGNOS will cover
most of Western Europe.
Restart GPS:
Restarts the GPS receiver, satellite reception will
be lost until the receiver completes its restart and
acquires the satellites.

16-6 Installation: Northstar petrol/gasoline sensors

Fit the optional petrol/gasoline fuel kit following
the instructions supplied with the kit.
Note:
• Fit one kit for each engine, up to two engines.
• SmartCraft™ engines have fuel flow sensors,
therefore Northstar fuel sensors are not
required as well.
• Wire for auto power (see section 16-4).
During setup enter fuel setup data
(see section 15-4)
