1.1 Description of compass.
The Autonnic NMEA compass unit is a complete component for a compass indicating system,
RADAR 'North-up' input or autopilot. It is housed in a water-resistant enclosure so it can be
mounted outside a steel hull. It delivers heading data in two industry-standard forms. .
The A5022 contains a fluxgate with floating core surrounded by high-precision interface circuits
which, together with the special clockwise/anticlockwise and offset nulling sequence allow a
microprocessor to acquire a binary value from two orthogonal sensors of the horizontal
component of the Earth's magnetic field. The processor calculates the vector from these
values, uses a calibration table to correct for local field disturbance errors, offsets the result
and then presents the data in a manner which has been requested. Such requests alter the
