Sensis Deploying Multilateration for Precision Runway Monitoring at Detroit Metropolitan Wayne County Airport

Sensis MDS is the first and only certified multilateration system that allows simultaneous approaches to closely spaced parallel runways

EAST SYRACUSE, NY – March 11, 2008 – Sensis Corporation today announced that its certified multilateration surveillance system, Multistatic Dependent Surveillance (MDS), is being deployed for Precision Runway Monitoring (PRM) at Detroit Metropolitan Wayne County Airport (DTW). Sensis MDS will provide surveillance for simultaneous parallel approaches to runways 4 and 22, enabling Detroit Metro to increase its capacity.

In 2005, Sensis successfully demonstrated to the FAA that multilateration is a technologically sound solution for PRM based on a testing at Lambert – St. Louis International Airport. The multilateration system met the defined coverage volume, positional accuracy, and Modes 3/A and C code accuracy requirement. Following this testing, the FAA conducted a cost/benefit analysis which indicated that in addition to its technical strength, based on the minimal maintenance it requires, multilateration is more cost-effective than Electronic-Scan (E-SCAN) PRM. As a result, the FAA contracted with Sensis to deploy MDS for PRM at Detroit Metro Airport, in addition to the Airport Surface Detection Equipment, Model X (ASDE-X) system already scheduled to be installed.

“The high accuracy and update rate of MDS enables Sensis to deliver the industry’s first multilateration system for PRM that allows simultaneous approaches to closely spaced parallel runways,” said Tony Lo Brutto, Vice President and General Manager of Sensis Air Traffic Systems. “Sensis MDS uses inexpensive, easy-to-maintain sensors that exceed the very precise surveillance demanded by PRM. With MDS implemented, airports such as Detroit Metro will have a certified, cost-effective alternative to 1980s E-SCAN PRM radar technology.”

Sensis MDS uses multiple sensors to triangulate aircraft positions based on transponder signals to provide a one-second update rate for positive identification in all weather conditions. In addition, it is compatible with Automatic Dependent Surveillance – Broadcast (ADS-B). Sensis is also deploying its MDS for PRM at Sydney Airport in Australia.

The PRM system for DTW has completed Factory Acceptance Testing and is currently deployed and undergoing testing at the airport.
