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.
Automatic dependent surveillance-broadcast
A prominent moment of the 2003 International Operators Conference in Colorado Springs occurred just after the first day’s sessions. With dozens of pilots and aviation department managers standing around a nearby television, President Bush warned Saddam Hussein that the Americans and their allies were on the way. The war in Iraq erupted soon afterwards.
The FAA made a hard sell yesterday to offshore oil operators that will soon have the opportunity to receive unprecedented traffic and weather information in the cockpit via ADS-B (automatic dependent surveillance-broadcast) technology–if they equip their helicopters with special equipment that can receive and display
In a letter to the Department of Transportation last month, AOPA renewed its support of loran as a possible low-cost, ideal backup to the future GPS-based ATC system. The letter went to the Coast Guard because it is responsible for operation and maintenance of loran.
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.
Industry observers expect protests from Lockheed Martin and ITT claiming that Raytheon enjoys an unfair advantage in the FAA’s reported $1.5 billion nationwide ADS-B program, following the agency’s announcement that all three qualified as bidders.
The FAA assumed that its chosen ADS-B program bidders–Lockheed Martin, ITT and Raytheon–would submit competitive offers on the expected system configuration. This service would be provided to GA through the FAA-developed 978 MHz UAT system, and to other users through the internationally standardized 1090 MHz frequency.
Nav Canada announced last week it plans this year and next to install ADS-B ground stations around Hudson Bay, which straddles high-latitude airline flight paths linking Asia, North America and Europe, but which has no radar coverage. Currently, aircraft overflying the area must observe “procedural” separations that keep them about 80 miles apart, compared with five miles under radar monitoring.
Germany’s air navigation service provider (ANSP), Deutsche Flugsicherung (DFS), has agreed to buy the SITA network of 27 VHF datalink (VDL) ground stations in the country.
Raytheon Systems Limited (RSL) has unveiled a new automatic dependent surveillance-broadcast (ADS-B) receiver that uses a 16 MHz or better sampling rate, a new algorithm and enhanced error correction to decode 1,090-MHz extended squitter transmissions correctly even in the presence of extreme frequency congestion.
