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.

CONFIGURATION
Configuration information is stored internally in the microprocessor's flash memory. 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.

CONNECTIONS
The DRM4000L has a Samtec TFM-105-02-S-D-LC connector on the circuit board for the J1 electrical interface. 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.
