The University of Florida is seeking a company to license The Gator Communicator Model IV. This device is the result of twenty plus years of experience developing geographic information systems and six years of experience developing pen computer based remote data collection applications. The Gator Communicator was designed to be an integral component of a real-time, mobile Geographic Information System and utilizes the Global Positioning System (GPS).


  • Location data collection and mapping with realtime correction value transmission from a base station
  • Magnetic direction determination using a digital compass
  • Pitch and roll reporting via dual inclinometers
  • Image pair collection by digital cameras, providing offset vector measurements
  • Wireless data transfer from distances as great as 20 miles with a 900 MHz digital packet spread spectrum two-way radio
  • Digital image and field data storage utilizing an internal solid-state flash drive and removable Personal Computer Memory Card International Association (PCMCIA) card


  • Convenient touch screen eliminates the need for a keyboard and mouse
  • Low-power consumption electronic components and rechargeable “smart” batteries increase energy efficiency and reduce power expenses, respectively
  • Rugged design prevents water damage and extends instrument life
  • Compatibility with serial and Ethernet ports allow ‘hard-wire’ connections to other computers
  • OS-9 real-time operating system permits wireless upload of application upgrades
  • Personal Java allows iconic-interface control of software applications


The Gator Communicator is designed to aid in the collection and verification of planning and engineering field data. This personal digital assistant (PDA) will meet the needs of the construction and utility industry and is applicable to other tasks, such as environmental sampling, agricultural field data collection, property appraisal and construction inspection. Large opportunities for use also exist in the gas, water, sewer, telephone and cable TV utilities; in local, state and federal government inspection agencies; and in the insurance and transportation industries.
