SENSIS MULTILATERATION AND ADS-B SYSTEMS TO BE USED IN ZURICH AND GENEVA AIRPORT’S A-SMGCS PROGRAMDEWITT, NY - November 1, 2001 - Sensis Corporation received a contract to provide an advanced air and surface surveillance system as part of the Swiss Advanced Surface Movement Guidance and Control (A-SMGCS) program for Zurich and Geneva airports. The Sensis system utilizes multilateration techniques based on ATCRBS and automatic dependent surveillance - broadcast (ADS-B) data to locate and track all transponder equipped aircraft and vehicles. Sensis is a subcontractor to Park Air Systems who will provide data fusion, display systems, and integration to the surface movement radar.
The Sensis system locates and identifies targets by utilizing small sensors on the airport surface that listen for transponder signals and triangulate them to determine the position of the signal's source. The transponder signals are encoded with aircraft data which the sensors decode and provide to air traffic controllers. Traditional ATCRBS transponders typically provide aircraft identification and altitude information. Advanced Automatic Dependent Surveillance - Broadcast (ADS-B) transponders also broadcast latitude, longitude, velocity and heading information - as determined by the on-board avionics and Global Navigation Satellite Systems.
The A-SMGCS program is designed to increase airport safety, capacity, and efficiency during high traffic and/or poor weather conditions. The program involves the integration of existing Surface Movement Radars (SMRs), integration of new X-band SMRs, a multilateration/ADS-B system, sensor data fusion, vehicle tracking, data recording and playback capability, and new controller work stations. Phase I of this contract will cover the portion of Zurich airport where the new midfield terminal is being constructed. Phase II will expand the Zurich system to cover the entire airport and will also provide a complete A-SMGCS system for Geneva international airport.
Sensis Corporation provides sensors and information technology to the world's militaries, civil aviation authorities, airports and airlines. The company designs, manufactures and installs multilateration/ADS-B ground stations for air and surface surveillance, and sensor data interface equipment for integrating new and legacy surveillance and automation systems. Sensis equipment is deployed around the world, including more than 80 multilateration/ADS-B sensors and 700 data interface devices in 25 countries on five continents.
