The SMGCS is based on the Logitrac, developed by Transtech. The Logitrac system enables the DCMS to control and monitor each individual lamp and sensor on the runway/taxiway without changing the airport infrastructure. This technology uses the existing airfield cables as a communication network.


Transtech has incorporated this ability into several systems:
  1. Stop Bar System - manages the entry and exit of airplanes to and from runways.
  2. Runway Guard Lights (RGL) - RGL are to be used at all runway and taxiway intersections in low visibility operations (below 1200 Ft RVR). Using the Logitrac, Transtech controls and monitors this critical device.
  3. Failed Lamp Locator (FLL) System - FAA/ICAO regulations require the FLL system in order to operate an airport under low visibility conditions (CAT II/CAT III).
  4. Sign monitoring - guidance signs are key visual aids used to direct aircraft around the airport movement area. Sign monitoring provides the airport with real-time and historical information on the status of the signs.
  5. Complete SMGCS solution - Combination of Stop Bars, Runway Guard Lights and FLL systems.
The Logitrac units can be supplied as a stand-alone configuration, or as part of the DCMS.
