The KW941-D allows a new heading sensor such as a gyro, magnetic compass
or satellite heading sensor to connect to existing bridge repeaters or existing
radars and navigational aids. The KW941-D is useful in both retrofit and new
installations.
Case Study
A Motor Tanker had a Sperry Mk 37 Gyro that developed a fault and had to be
replaced. The replacement Gyro only had a NMEA output, to reduce the cost of
replacing the original motorised repeaters a KW941-D for a fraction of the
replacement cost.
