The Trackertm

Covert Electronic Tracking System, Complete System (Order #6500) Beeper Bumper System

The Tracker is a revolutionary new Radio Direction Finder (RDF) and electronic tracking system designed specifically for law enforcement covert tracking. Consisting of a 4-antenna DF array for magnetic mounting on a vehicle and an enhanced Doppler DF processor with proprietary DSP algorithms, the Tracker is ready to monitor almost any type of electronic tracking beacon and provide you with a bearing and relative range to the signal.




Specifically designed for law enforcement and military applications, the Tracker overcomes the serious problem of multipath interference common to virtually every other radio direction finder. Two powerful microprocessors apply newly developed algorithms to analyze and discard confusing indications due to phase shift from multipath signals. The result is a clear, unambiguous bearing to the target. TheTracker is very easy to use even for non-technical personnel.

Multi site RDF networks are simple to implement. TheTracker includes an RS232 port, and the unit can overlay NMEA GPS data from virtually any GPS receiver onto the DF bearing and output the data to a laptop running a mapping program. Additionally, our TRACKnet software can be used to implement small or large area coverage multi-site applications where DF bearings from allTracker-equipped stations are linked via a packet data channel and displayed simultaneously in realtime on all computers in the net. This application is common in man-critical work such as kidnaping/ransom tracking, executive protection, drug interdiction, etc. A simple beacon is all that is needed in the package to be tracked.



Vehicle Tracking Transmitter "Bumper Beeper"
P/N TRV-2W - Vehicle Beacon with Motion Sensor

Use the Tracker to follow and locate body wires, vehicle tracking beacons, tagged CDS shipments or cash packages, stuck transmitters, pirate/stolen transmitters, deliberate or inadvertent interference, covert beacons, HAZMAT shipments, etc. Anywhere you need to follow an RF signal is a job for the Tracker.
