Simrad HS50 Heading Sensor
48 20221081 / F
Reduced heading indication
The reason for reduced heading performance could be one of the
following:
• The number of GPS satellites the Sensor unit is able to see is
too few. Press the NAV2/POS button until the Skyplot view
appears. Check that at least four satellites are available and
that the PDOP value is less than 6. Refer Satellite Skyplot
display, page 37.
• Check also the number of common satellites seen by the two
GPS antennas by pressing the INFO button and looking at the
value for Common sat. in the advanced heading information
display as shown in page 38. The number of common
satellites have to be two or higher to determine a heading.
If one of the criteria's above not is fulfilled, it may be an
obstruction between the Sensor unit and the GPS satellites.
Consider moving the vessel to another location to see whether
that helps.
If it is still reduced after checking the above items, consult your
nearest Simrad dealer for assistance.
Simulated data
If the HS50 system is not sending out real data, check whether
the system is operation in demonstration mode with only
simulated output data. If the system operates in demonstration
mode the text DEMO appear at the bottom of the status field as
shown in the figure.
Refer Expert setup, page 30.
