New Technology Allows for Location Tracking with Minimal Hardware Investment

LEBANON, N.H. & BOSTON—(BUSINESS WIRE)—March 4, 2004— Geographic Data Technology, Inc., a developer of premier map databases, and TeleType Co. have teamed to turn GPS/Java enabled phones into tracking devices that can locate family members, high profile executives, fleet vehicles, and security and service personnel. Based on TeleType's award-winning GIS tracking and navigation software and GDT's industry-standard digital maps, this new mobile tracking solution can also serve as a high-end mobile navigator combining street, air and marine information.

The TeleType GPS PhoneTracker represents the type of innovative technology recently recognized by the CNET Editor's Choice Award for TeleType's WorldNavigator GPS technology for PDAs and laptops. By combining Global Positioning System (GPS) technology with communication and location transmission into the GPS/Java enabled phone, TeleType offers customers an economical and easy-to-use system that can simultaneously track multiple vehicles.

The PhoneTracker uses a GPS/Java enabled phone with a public IP reserved for data transmission so that it is secure, fast and reliable. Because no computer is required in the vehicle, the PhoneTracker can track entire fleets of vehicles with minimal hardware investment per vehicle. Each GPS/Java phone enabled vehicle can be tracked by anyone on the road or from a central tracking station with an Internet enabled Pocket PC, laptop or desktop PC.

"TeleType's innovative solution allows customers to easily and cost-effectively keep track of both assets and employees," said Dana Fenner, Location-Based Services Market Director for GDT. "Companies are no longer required to install costly hardware systems in vehicles. Now, they can use a GPS/Java enabled phone, which many commercial fleets already use. This puts GPS tracking technology into the hands of many more businesses and consumers."

GDT's Dynamap(R)/Transportation street and address information provides a detailed map backdrop and enables the system to accurately pinpoint locations. Compiled from a vast network of sources, the Dynamap/Transportation map data provides comprehensive street and address coverage, highly accurate one-way and restricted turn information, accurate representation of limited access highways, preferred routing names, and exit point layers to offer superb performance within the TeleType PhoneTracker.

"The accuracy and reliability of GDT's street and address data has been a key factor in the development of many of our tracking solutions," said Ed Friedman, President of TeleType. "The GDT map database provided the level of information we needed to enable the GPS/Java phone with location intelligence."
