SYSTEM AND METHOD FOR TRACKING A PERSON
First Claim
1. A deduced reckoning system for tracking a person, comprising:
- a deduced reckoning device containing a plurality of directional sensors configured to sense a movement of the person along a path;
a digital processor coupled to the directional sensors and configured to output information to enable a change in position of the deduced reckoning device to be determined based on a change in output from the directional sensors;
a transceiver connector operable to connect to an external transceiver configured to transmit the output information from the digital processor;
a tracking device connector operable to be connect to an external radio frequency tracking receiver configured to receive an approximate location of the deduced reckoning device based on a plurality of radio frequency signals to supplement positional data provided by the plurality of directional sensors; and
an external sensor connector operable to connect at least one external sensor to the deduced reckoning system to enable data collected by the at least one external sensor to be transmitted by the external transceiver.

Abstract
A system and method for tracking a person using a deduced reckoning device is disclosed. The method includes the operation of selecting an initial location of the person. The person'"'"'s movement along a path is then monitored using directional sensors, including a digital magnetic compass, at least one accelerometer, at least one magnetometer, at least one gyroscope, and an altimeter. The person'"'"'s changing location is recorded based on a change in outputs of the directional sensors that occur during the person'"'"'s movement. The person'"'"'s changing location is transmitted to a command and control center. The person'"'"'s changing location is then displayed on a graphical user interface at the command and control center.
