GPS - GLONASS Computer-Aided Dispatch (USB)

GPS- GLONASS Computer-Aided Dispatch - USB Version: CAD-800U


Midian's CAD-800U is the computer-aided dispatch unit/Windows® software for use with Midian's GPS-GLONASS speaker microphone products. GPS is the United States' global navigation satellite system (GNSS) format. GLONASS is the Russian equivalent of the US GPS System. When the GPS-GLONASS speaker microphone is keyed it sends the PTT ID (ANI) and the GPS-GLONASS coordinates. The CAD-800U decodes and displays the PTT ID along with the GPS location and other selectable information shown on a map using Google Earth or Terrain Navigator Pro with no monthly subscriber fees.

The CAD-800U can encode functions to Midian's GPS speaker microphones such as Polling, Selective Calling, Radio Disable, Radio Enable, Spy (Remote Monitoring) and Emergency Acknowledge. Polling allows the dispatcher to request a unit's GPS-GLONASS location. Selective calling can be used to call an individual unit, a group of units or all units. If a unit becomes lost or stolen, it can be disabled, so it cannot interfere with the system. If the unit is later recovered the unit can be re-enabled. The Spy function enables the dispatcher to eavesdrop on a unit during an emergency or other condition. If multiple Emergency IDs are transmitted, the dispatcher can stop subsequent Emergency ID transmissions using the Emergency Acknowledge feature.

The Google Earth Interface to Midian's CAD-800U enables the dispatcher to track a user's route throughout the course of the day and if a user goes outside of its zone (geo-fencing). Icons are programmable for the system or unique to each zone.
