Simrad HS50 Heading Sensor
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.
