The Mobile Digital Communicator (MDC) has been designed to interface with GPS receivers that adhere to the NMEA (National Marine Electronics Association) 0183 standards.  This standard defines the electrical signaling requirements, data transmission protocol and time, and specific sentence formats for a 4800-baud serial data bus.   NMEA 0183 compliant GPS devices provide excellent results for a typical MDC application and are widely available from many commercial retailers and on-line suppliers (many on E-bay) and are relatively inexpensive with good quality units being available for under $100.00
   



  
This is an example of a magnetic mount  GPS receiver that plugs directly into the USB port on your laptop computer.  
  
Having a GPS receiver connected to your MDC allows for the transmission of real time latitude and longitude coordinates back to CAD/Dispatch so that dispatchers as well as other MDC users can view field units spatially via the MDC or CAD map display.

The MDC software also uses a Reverse Geo-Coding process to automatically convert latitude and longitude coordinates into the nearest calculated street address for Unit Status command dialogs such as Vehicle Stops; Subject Stops; Field Events and other transactions where location data is normally provided and transmitted as part of the status command.
