Midian's TS-130-SM1G-SB is a GPS / GLONASS speaker microphone that can connect to most conventional analog and trunked portable two-way radios. When the GPS / GLONASS speaker microphone is keyed it will send the PTT ID (ANI) and the GPS / GLONASS coordinates. The unit also supports sending of an Emergency ID with Location when activated by a button press, the Lone Worker feature or the Man-Down feature. Midian's CAD-800 base station controller decodes and displays the PTT ID along with the GPS / GLONASS location and other selectable information shown on a map using Google Earth or Terrain Navigator Pro with no monthly subscriber fees.

The TS-130-SM1G also supports decode functions such as Polling, Selective Calling, Radio Disable, Radio Enable, Spy (Remote Monitoring) and Emergency Acknowledge. These decode functions are initiated from Midian's CAD-800. Polling allows the dispatcher to request a unit's GPS / GLONASS location. Selective calling can be 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.
