DRM4000
Dead Reckoning Module
The Dead Reckoning Module (DRM) 4000 is a miniature, electronic device for
personnel on foot that provides the user’s position relative to an initialization point.
Dead Reckoning (DR) data and external GPS NMEA data are blended by an
internal Kalman filter. When GPS data is available the dead reckoning sensors are
automatically calibrated continuously and the two data sources are blended into a
composite real-time position data output.
When GPS data is unavailable, dead
reckoning takes over. DRM4000 position error characteristics are independent of
time, and depend primarily on distance traveled.
Patented motion classification algorithms (SmartPedometry) analyze walking
motion, and compensate when the user is running, or just “fidgeting” in place.
An automatic compass orientation
algorithm provides accurate azimuth information when the user is upright or prone.
Commercially available gyros are
included to compensate for transient magnetic disturbances and transient accelerations that may interfere with compass
operation. A barometric altimeter provides vertical position accurate enough to discriminate between floors of a building
(1.5 meter accuracy). High fidelity azimuth data from the magnetic compass is also available for use by the host system.
The DRM4000 unit can be directly interfaced to many GPS receivers and man-pack computers, and includes capabilities
for accurate field calibration. The DRM4000 is a reliable GPS supplement for personnel on foot. The unit is small enough
to be easily integrated into torso-mounted devices, and does not require any sensors on the legs or feet. Applications for
the DRM4000 include personnel tracking (fire, police, and security), real-time waypoint navigation, disaster relief
operations, and cell phone signal strength mapping.
FEATURES & BENEFITS
4 State-of-the-art dead reckoning device for personnel navigation.
4 Continuous, gap-free, personnel position location, with or without GPS. Typical DR accuracy 2% distance traveled.
4 Internal Kalman filter integrates dead reckoning position with external GPS, using NMEA0183 format
4 Digital compass azimuth accuracy better than 1°
4 Low power consumption (<0.5 watt) and small size (2 x 2 x 0.5 inches) for man-portable applications
4 Built-in World Magnetic Model for accurate true direction anywhere (automatic declination)
4 Motion classification and adaptive algorithms maximize accuracy under difficult conditions
4 Sensors include 3 commercial grade gyros, 3 accelerometers, 3 magnetometers, and barometric altimeter
4 Industrial temperature range (-40° to +85°C) for wide environment usage
4 Available as a circuit card module with RS232 interface for customer integration. A demonstration kit is also available
which includes an enclosure with an internal I/O adapter board with a USB interface, GPS receiver, rechargeable
lithium battery, Windows Host software, carrying case, GPS antenna, baseball cap and 6-foot USB adapter cable.
The mini-USB jack accommodates 38.4kbps data transfer as well as trickle charging the battery when required. An
illuminated power on/off doubles as a momentary "event" marker button to help in data collection processing.
