Simrad HS50 Heading Sensor 

32 

20221081 / F 

The average value for observations from each of the two 
different systems should then be used, and the offset between 
the two systems (reference value minus HS50 reading) input as 
the 

Head offset

 value. 

The offset value can be either positive or negative. 

 

Example: 

If the heading measured by the reference system is 32.1° and the 
HS50 heading 28.5° during the calibration period, 

3.6

 (32.1 - 

28.5) should be entered in the 

General

 submenu as the 

Head 

offset

 value.
