Digital Compass Module
HMR3000
Lectronic compass module that
Provides heading, pitch and roll
Output for navigation and guidance
Systems.Honeywell's
Solid state magnetoresistive
Sensors make this strapdown
Compass both rugged and reliable.
This compass provides
Fast response time up to 20
Hertz and high heading accuracy
Of 0.5 with 0.1 resolution.
APPLICATIONS

FEATURES AND BENEFITS
Fast Response Time Built with solid state magnetic sensors and no moving parts improves
Response time, allowing faster updates compared to gimballed fluxgates.
Small Size Available as a circuit board 1.2 x 2.95 inches, weighing less than one
Ounce, or in an aluminum enclosure.
Low Power Operates with less than 35 mA, allowing for long operation with a battery.
High Accuracy Accuracy better than 0.5 with 0.1 resolution for critical positioning
Applications.
Wide Tilt Range Tilt range of +/-40 for both the roll and pitch allows operation for most Applications.
Hard Iron Compensation Calibration routines to compensate for distortion due to nearby ferrous Objects and stray fields, such as vehicles.
User Configurable Features User settings of baud rate, update rate, output format, units, Filter settings, deviation angles, alarms and warnings are stored internally in non-volitile memory.
KVH C100
KVH's C100 Compass Engine is an innovative stand-alone design offering small size, low cost, and system flexibility to meet your demanding heading sensor applications.
