Austria Selects Sensis WAM System

By Tish Drake | May 16, 2011

Austro Control GmbH, the Air Navigation Service Provider for Austria, has selected Sensis, of Syracuse, N.Y., to deploy a Wide Area Multilateration (WAM) system. The system will provide surveillance of Austria’s airspace to air traffic controllers, and will also meet future European mandates by supporting Automatic Dependent Surveillance – Broadcast (ADS-B) and providing data validation of ADS-B.

The Sensis WAM system will provide terminal and en route surveillance of the entire country, including Austria’s mountainous regions, encompassing more than 32,000 square miles. The system will provide surveillance of Mode S, Mode S Extended Squitter and Mode A/C equipped aircraft and ADS-B. Austro Control will use the WAM system to complement their existing Secondary Surveillance Radar (SSR) infrastructure while adding surveillance of areas not previously covered by SSR due to the terrain.

Sensis multilateration uses multiple non-rotating sensors to triangulate aircraft locations based on transponder signals to provide air traffic controllers with precise aircraft position and identification information. Additionally, each multilateration sensor deployed by Sensis supports ADS-B.

“The Sensis WAM solution for Austro Control is based on years of experience in developing, deploying and commissioning systems around the world that meet stringent requirements in the most challenging operating environments,” said Ken Kaminski, vice president and general manager of Sensis Air Traffic Systems. “The Sensis solution meets all current WAM requirements and provides the infrastructure to meet tomorrow’s ADS-B mandates while providing a valuable validation source for ADS-B data.”
