  1. GPS Hardware Overview Presented by: Mark Friederick

  2. GSM/GPRS GPS Device This is the main GPS unit and is the heart of the vehicle mounted system. This GPS collects the GPS coordinates of the vehicle and passes data to our server via GPRS (Cellular communication). This GPS also passes data from our server to the Garmin GPS if the Garmin is installed. The data is passed from our server to the customer server.

  3. GSM enabled SIM Smart Card This type of SIM Smart Card is inserted into the main GPS unit. After that the GPS unit is Programmed. The data from the GPS device will be passed through the ISP to the Global One Fleet server at the DBS Offices. The GPS unit uses the GSM band with the GPRS protocol.

  4. Garmin GPS This is the Garmin GPS unit. This GPS displays information from the customer dispatch board. This GPS can also send information such as SMS messages back to the dispatcher. The normal function of the Garmin GPS is to receive a service call from the dispatch board and map a route from the current location to the call. After the call is complete the technician can send a message from the Garmin that the call is complete. The Technician is also about to sent other messages.

  5. GPS & GSM Antenna The antenna should be tied under the dash in close proximity of the windshield and out of the sun. Try to mount in the correct direction. Don’t stress the antenna in any way as this may cause a failure of the antenna. Try to position away from other antennas. The word BOTTOM should always face away from the sky. Don’t remove the double sided tape for any reason, the antenna will probably be destroyed if you do.

  6. Wiring DiagramWiring Diagram for all vehicles with Garmin Wiring Diagram with Garmin option. We recommend that installation of fuses as shown.

  7. Future GPS Units • Davisware is integrating with a new GPS. This will not be used with a Garmin and will be primarily for companies that use Field Service. The pictures below is a preview of one of the units.
