Inertial Aerosystems announce the availability of a new, low cost microprocessor controlled compass module. Designated the HMR3500, this high performance device has a 3-axis digital compass solution with a customisable co-ordinate system for mounting in any desired orientation.
Incorporating three anisotropic magneto-resistive sensors and three accelerometers combined to provide compass heading as well as pitch and roll angles.
Included are provisions for hard and soft iron correction algorithms to handle magnetic distortion effects. A world magnetic model feature is provided to automatically add declination angle corrections for reference to true north.
This innovative product has less than 1 degree nominal heading accuracy with 0.1 degree resolution, with update rate up to 26Hz, + or - 89 degree pitch and roll with 360 degrees continuous roll capability. Operating temperature range of -40 to +85 degrees C and requiring only 5 Volts D.C.
Ideal where space and weight are at a premium the the printed circuit version measures 39.88 x 50 x 13.21mm's and weighs 17 grams. The device is also available as a development kit in an enclosed black aluminium case with cable assembly and software, weighing 85 grms.
This versatile product can be used in navigation, dead reckoning, personal and onboard navigation, and measuring tilt / movement of machinery, vessels, buildings, robotics and unmanned vehicles
The HMR3500 has applications in the Engineering, Electronic, Manufacturing and Processing Industries.
