Avinor AS, Norway's Air Navigation Service Provider, selected Sensis Corp.'s multilateration and VeeLo NextGen vehicle locators for Bergen Airport, Flesland, to provide surveillance of the runways, taxiways and stand areas along with the location of vehicles operating on the surface.
Sensis multilateration uses multiple non-rotating sensors to triangulate aircraft and vehicle locations based on transponder signals to provide air traffic controllers with precise aircraft position and identification information in all weather conditions. Each multilateration sensor deployed by Sensis supports Automatic Dependent Surveillance – Broadcast (ADS-B).
VeeLo NextGen is a small, light weight device in a rugged, weather-resistant enclosure that is attached to the exterior of an airport vehicle to provide air traffic controllers with situational awareness of vehicles operating on the airport surface. The vehicle locator attains its position from a Satellite-Based Augmentation System (SBAS)-enabled GPS receiver and broadcasts its location and identity using the Mode S Extended Squitter ADS-B message format. VeeLo NextGen automatically turns off when the vehicle travels outside of the movement area, ensuring an efficient use of available aviation spectrum.
