Pitch and Roll corrected to ±45˚

The Autonnic Compass Sensor uses fluxgate technology to provide the most accurate magnetic heading, meeting the requirements of all navigation displays and devices on board. The electronic compass unit is weather tight, allowing an optimal installation position inside or outside the hull.  The compass works by taking the magnetic heading and converting it into a digital signal for use by chart plotters, Autopilots, AIS systems and other electronic devices onboard.

In the A5041 gyro model, heading output is additionally derived by integrating the rate output from a MEMS yaw accelerometer or ‘gyro’ which is drift-corrected by a fluxgate magnetometer with pitch and roll compensation up to 45°.

Simrad Legacy Compass 

Older Simrad® Autopilots can be kept going with this functional alternative to the RFC35.

Add an Autonnic Indicator (A5501) to make a complete TMC.  


The A4032 gives a NMEA 0183 heading directly from the Ships’ Compass.


Manually calibrated to the Master Compass.


Centre-hole fixing.

The A4032 Autonnic Compass Pick Up Sensor takes the magnetic data generated by an existing yacht compass and converts it into NMEA0183 data to use for a variety of on-board purposes. The Pick Up Sensor avoids the need to install a standalone compass unit minimising cost and system complexity. Its roots are found in larger vessels where the ship’s compass is precisely calibrated and for certification purposes acts as the reference point for all navigation systems.
