There is a Phenomenon called "northerly turning error" that causes marine autopilot performance to degrade. This error causes the autopilot to have difficulties keeping on course when steering in a northerly or southerly direction. ComNav is now offering its Rate Stabilizer to correct this error.
This plug-in addition to an existing ComNav fluxgate compass also greatly improves the high-speed performance of the autopilot. The Rate Stabilizer corrects these errors by using "vibrating gyro technology."
With an easy-to-use socket connection for the fluxgate compass and a 40' cable for connection to the autopilot, the Rate Stabilizer can be easily added to both new and existing installations. The Rate Stabilizer is equipped with a NMEA 0183 terminal, supplying stabilized heading output for interfacing with other equipment, such as radar and sounders. The compact unit measures 5.6" x 4.2" x 3" and is easily mounted.
