The DRM™ 4000 Dead Reckoning Module provides accurate position information for people on foot in places that the global positioning system (GPS) is unable to reach. The small unit contains ten sensors including three gyros, accelerometers and magnetometers as well a barometric altimeter to accurately deliver position location. According to the company press release “It nominally provides position data that is accurate to within 2% of the actual distance traveled by a user in environments without GPS”, a 10 meter accuracy for 500m travelled.
“The miniature size of this state-of-the-art dead reckoning device enables man-portable applications like personnel tracking, disaster relief operations, safe pathway guidance and mapping tasks,” stated Tamara Bratland, Director, Magnetic Sensors, Honeywell Defense and Space. “The DRM4000 uses patented motion classification algorithms to analyze walking motion and compensate for unique user kinematics.”
Obviously this kind of high end dead reckoning module will not find its way in a consumer product in the next six months. Nevertheless, dead reckoning sensor are making their way to navigation devices. At the Computex Tradeshow in Taiwan this week Mio presented its new Smartphone Mio A702 integrating both a GPS and a dead reckoning sensor from SiRF (SiRF Direct technology). With indoor mapping making its way at Navteq with the acquisition of The Map Network, indoor pedestrian navigation using dead reckoning technologies might not be that far away.
