RATE OF TURN

Rate of Turn Damping Period Selection by NMEA 0183 
Interface

The SSHS is capable of measuring a vessel’s rate of turn and outputting the information over 
both the NMEA 0183 and NMEA 2000 interfaces. Furthermore, the SSHS has a 
programmable damping period where the filter time can be increased for very slow turning 
vessels such as tugs pushing barges. Also, the SSHS rate of turn indication may be zeroed to 
correct for any temperature-induced offset.

The SSHS can be programmed with different damping periods and have the rate of turn 
indication zeroed using the NMEA 0183 Interface. See 

Appendix A 

for details on 

programming the SSHS to use a specific damping period.

Rate of Turn Zeroing

The SSHS may be used as a rate of turn indicator, which should read zero when the vessel is 
not turning. It is possible that the rate of turn indication has an offset; that is, it may show a 
non-zero value when the vessel is at rest. This offset changes with temperature but the SSHS 
has the ability to remember the offset at different temperatures.
