At the Air Traffic Control Association’s annual convention this fall, Syracuse, N.Y.-based Sensis announced that its multilateration system will replace the legacy precision runway monitor (PRM) radar used at the Sydney, Australia airport, to monitor aircraft flying simultaneous approaches to its closely spaced parallel runways, 16L and 16R.

One of the newest ATC techniques is multilateration, where several small unattended receiving stations are dispersed around an airport to monitor transponder and TCAS transmissions from aircraft in the area. The received signals are then computer processed to pinpoint the exact location and identity of each aircraft.
The Colorado Department of Transportation has launched a new technology initiative that will provide enhanced surveillance, and thereby improve access, to its many mountain airports. Currently, IFR flight operations at those locations are limited because surrounding mountains block the line-of-sight signals of the FAA’s ATC secondary (transponder interrogating) radars, preventing the monitoring of lower-level arriving and departing traffic.
The FAA placed production orders for 11 of Sensis’ airport surface detection equipment systems, Model X (ASDE-X). This requisition is in addition to the 21 initial systems ordered in December 2002. The production option for the 11 ASDE-X systems, in addition to associated hardware, software and support, is worth approximately $35 million.
Nav Canada last month awarded its national ADS-B program to Syracuse, N.Y.-based Sensis, and installation of the first system ground stations is now under way. The FAA, on the other hand, faces some unexpected pre-contract issues as it moves toward its implementation plan.
Beijing’s Capital International Airport, expanding to handle 2008 Olympics traffic, has opted not to use traditional radar monitoring of simultaneous approaches on its future parallel runway layout.
More details about Canada’s proposed ADS-B network have been disclosed. As reported last week, Sensis of Syracuse, N.Y., won a Nav Canada contract covering up to 200 ADS-B stations for selective deployment across the country. Six dual installations are planned around Hudson Bay, currently non-radar airspace.

Sensis is building on its experience of automatic dependent surveillance-broadcast (ADS-B) in the FAA-sponsored Capstone trials in Alaska and the increasing use of its multilateration technology with the development of a 1,090-MHz receiver that is under consideration for deployment on the U.S. East Coast and preparations to deploy a multilateration system at Juneau, Alaska.
