TruePoint™ Compass Module
HMR3500
The HMR3500 TruePoint™ compass module is a 3-axis
digital compass solution with a customizable coordinate
system for mounting in any desired orientation. Three
Anisotropic Magneto-Resistive sensors and three MEMs
accelerometers are combined to provide compass heading
as well as pitch and roll angles.
The HMR3500 has provisions for hard and soft-iron
correction algorithms to handle magnetic distortion effects.
In addition a World Magnetic Model feature is provided to
automatically add declination angle corrections for
reference to true north (geographic north).
Honeywell provides product excellence and performance by introducing innovative solid-state magnetic sensor solutions.
These are highly reliable, top performance products that are delivered when promised. Honeywell's magnetic sensor
products provide real solutions you can count on.

    Heading computation uses the magnetic and tilt information inputs after compensation for errors. From the basic magnetic heading, a declination value may be added to arrive at a geographic north referenced heading. An index offset value may also be added to correct for mechanical installation misalignment on the target platform. www.honeywell.com...

Processor, memory, and disk space requirements are minimal. The CompassHost software is not described in this datasheet, but given in depth description in the HMR3500 user’s guide document. www.honeywell.com...
