Honeywell Introduces DRM 4000 Dead Reckoning Module

June 8, 2007

The miniature electronic navigation aid uses gyros, accelerometers, magnetometers, and a barometric altimeter to accurately deliver position location to first responders working in areas that a GPS cannot reach.


PHOENIX /BUSINESS WIRE/ -- Honeywell announced that it has added a DRM 4000 miniature electronic navigation aid to its existing line of dead-reckoning products.

The DRM 4000 Dead Reckoning Module provides accurate position information for first responders and other people on foot in places that the global positioning system (GPS) is unable to reach. The small, easy-to-integrate unit contains ten sensors, including three gyros, accelerometers, and magnetometers, as well a barometric altimeter to accurately deliver position location.

"The miniature size of this state-of-the-art dead-reckoning device enables man-portable applications such as personnel tracking, disaster-relief operations, safe-pathway guidance, and mapping tasks," stated Tamara Bratland, Director, Magnetic Sensors, Honeywell Defense and Space. "The DRM 4000 uses patented motion-classification algorithms to analyze walking motion and compensate for unique user kinematics."

The device enables a "wider variety of applications than previously designed modules" and can be extremely helpful to first responders in emergency and disaster operations, as well as to site inspectors and visually impaired persons for everyday navigation use.

The DRM 4000 contains an internal Kalman filter for integrating onboard sensors and external GPS data. It nominally provides position data accurate to within 2% of the actual distance traveled by a user in environments without GPS. The unit can be directly interfaced to many GPS receivers and man-pack computers and includes capabilities for accurate field calibration.

More information on the complete family of Honeywell's Dead Reckoning Modules, along with other products in the Magnetic Sensor line, is available on the company's Web site.
