Tilt Compensated Compass (Vertical)

Low cost SOLID STATE advanced Pitch / Roll / Temperature compensated COMPASS / MAGNETOMETER system is built around a state of the art CMOS microcontroller utilizing AOSI's proprietary algorithm on a 0.9" x 2" assembled PCB.  

The unit outputs continuous heading, magnetic field, dual axis tilt and temperature data over the standard USB, RS-232TTL,RS-232 rider PCB, RS-422 and  RS-485* interfaces. The AZIMUTH is generated from a 3 axis semiconductor magnetometer with 12 bit ( 0.08 deg ) resolution. The LINEAR tilt information is available with 12 bit resolution for +-90arcdeg in both Pitch and Roll axis ( +-180 deg optional ). COMPASS/TILT module is perfectly suitable for numerous navigation, antenna orientation, borehole profiling, research, training, construction, entertainment and other precision orientation,  and leveling applications. 

The COMPASS is able to output multi-sensor information in NMEA-0183 mode and responds to numerous generally used commands. Easy link through the Hyper Terminal Windows accessory facilitates custom calibration, hard iron compensation, data acquisition, data averaging, scan delay, dumping factor and data display.
