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 1.5″ x 2″ assembled PCB with a total height including tilt sensing elements of less then 0.5″.
The unit outputs continuous heading, magnetic field, dual axis tilt and temperature data over the standard RS-232 and 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 Pitch axis and FULL 360arcdeg in Roll axis.
COMPASS/TILT module is perfectly suitable for numerous navigation, research, training, construction, entertainment and other precision orientation, navigation 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.
Compass is available with a logging option that allows users to autonomously store up to 20000 reading for future DSP processing,
