         SURFACE DETECTION (CASD)

                                                      Detection (CASD) system is a Low Cost Ground Surveillance (LCGS)
                                                      system that revolutionizes the tracking of aircraft, service vehicles,

                                                      and avoid costly traffic tie-ups. In reduced visibility conditions, CASD
                                                      can see even if the operator can’t, helping limit the impact of adverse
                                                      weather, and keeping traffic flowing efficiently.
                                                      CASD provides this accurate tracking through the use of camera

                                                      sets are used to monitor a given area, which maximizes reliability in

                                                      CASD Camera Sensor sets incorporate the use of daylight/lowlight
                                                      cameras and thermal infrared cameras for continuous monitoring of
                                                      ground traffic in all-weather and low visibility conditions. The system

• Detect non-cooperative targets
• Improve traffic flow and avoid costly tie ups
• Increase overall safety
• Mitigate impact of adverse weather
• Minimal site preparation enabling easy
  installation and configuration
• More cost effective than traditional ASDE
  systems that require high-energy transmitters.
• CASD also requires no transponders or GPS
  systems, further reducing its cost
• Tracked target data can be fused with existing
  ground surveillance systems
