DRM™4000L Dead Reckoning Module The Dead Reckoning Module (DRM™) 4000L 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. DRM™4000L 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. 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, pitch and roll data from the magnetic compass is also available for use by the host system. The DRM™4000L unit can be directly interfaced to many GPS receivers and man-pack computers, and includes capabilities for accurate field calibration. The DRM™4000L 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 DRM™4000L include personnel tracking (fire, police, and security), real-time waypoint navigation, disaster relief operations, and cell phone signal strength mapping.

There are a finite number of write cycles to the flash. The limit will not normally be reached if changes are made manually. Care should be taken if the writing is performed automatically. Default board orientation is +Y axis up and +Z axis forward. The axes are printed on the module circuit board near the magnetic sensors. This orientation puts the module flat against the torso. The default RS-232 baud rate is 19200. A factory backup configuration is stored in the module. If an error is generated in the normal configuration, the backup configuration can be read and saved. The DRM4000L is stocked and ships in a standard configuration for RS-232 data inputs and outputs. The GPS NMEA0183 data input interface will be maintained from DRM input to the output plus the DRM unique commands and responses.

Possible mating connectors would be the Samtec SFSD-05- for wired assemblies and the SFM-105- for mating circuit boards. The table below shows the interface pin-out definition for J1.

DEVELOPMENT KIT The DRM4000L Development Kit includes a plastic enclosure with an internal I/O adapter board with a USB interface, GPS receiver, and a rechargeable lithium battery, Also included are the Windows™ DRM4000L Host Software, DRM4000L User’s Guide, carrying case, GPS antenna, baseball cap with Velcro antenna mount and a USB patch cable. It is highly recommended that first time users procure the development kit first, before ordering additional DRM4000L OEM modules. The mini-B USB jack on the DRM4000L kit enclosure accommodates data transfer up to 38.4kbps as well as trickle charging the battery when required. The pushbutton power on/off switch doubles as a momentary "event" marker button to help in data collection processing.
