Galileo Digital Magnetic Compass
GALILEO DMC300 is a versatile, low powered and compact digital magnetic compass. The device measures magnetic heading with high accuracy, and is suitable for land and marine applications.
DMC300 comprises triaxial solid state MEMS accelerometer and magnetometer sensors. Accelerometer is used to measure the roll and pitch in near-static conditions and magnetometer is used for estimation of heading. The roll and pitch measurements are used for tilt compensation of heading angle. The DMC300 runs a proprietary digital filter for noise reduction and computation of heading information even under dynamic conditions.
DMC300 is a plug-and-play device with configurable update rates and RS232 and RS485 interfaces. DMC300 is most suited for compassing, surveying, antenna orientation and other direction sensing applications.

FAQ
Yes using the software utility
Yes update rate is configurable using software utility.
The entire setup in which the DMC is installed needs to be rotated, for instance if installed in a boat the boat needs to be rotated in the horizontal plane for proper calibration (This procedure is called Compass swinging procedure (https://en.wiktionary.org/wiki/compass_swing)
Yes the compass is tilt compensated, it has accelerometers as gravity level to sense Roll, Pitch angles
