U.K. air traffic services provider NATS selected Era to provide its Squid vehicle tracking units for London Gatwick Airport. The Squid units will support the airport’s Advanced Surface Movement Guidance and Control System (A-SMGCS), which will go live in April 2008. Era said the system will provide air traffic controllers with complete surface situational awareness, by constantly and automatically transmitting vehicle locations to controllers. The company said the units work with any A-SMGCS and are standards compliant automatic dependent surveillance-broadcast (ADS-B) transponders that are mounted on top of airport vehicles.
