Compass Astra A5040 GYRO

A5040 allows to mount on your boat a NMEA0183 compass with two-axis calibration ±45°.

Grade of protection IP68

Two physical buttons for auto calibration and “zero-set”

The ideal for application on:

• Marine vehicles

• AIS
• Alarm systems

A5040 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 frequency of the data, the degree of filtering and the offset value. Calibration sequences can also be commanded.
