Sensis Corp.’s multilateration surveillance system at Stockholm-Arlanda Airport has passed site acceptance testing by Luftfartsverket Air Navigation Services (LFV), the Syracuse, N.Y.-based company said. The testing comes less than 12 months after the contract was awarded. The company said the system’s advanced surveillance accuracy and automatic labeling of aircraft and vehicles in the gate and movement areas will increase safety and traffic capacity on the airport surface. The system, Multistatic Dependent Surveillance (MDS), uses multiple non-rotating sensors to triangulate aircraft positions based on transponder signals. Also, Sensis said, the MDS sensors support Automatic Dependent Surveillance–Broadcast for easy migration to future technologies.
