Pelorus Navigation - Honeywell/Pelorus Satellite Landing System Achieves FAA Approval for Installation at Minneapolis, Newark.

CALGARY, Alberta--(BUSINESS WIRE)--MAY 21, 1996--PELORUS NAVIGATION (Alberta Stock Exchange: PN) The Honeywell/Pelorus Satellite Landing System (SLS-1000) moved toward Federal Aviation Administration certification by achieving FAA approval for installation at Minneapolis/St. Paul and Newark, N.J. international airports.

The SLS-2000 is expected to be the world's first certified system when it receivs FAA Special Category I certification this year.

In addition to the U.S. installations, the Satellite Landing System has been purchased for installation in Canada, Australia and Russia, with sales pending in several other countries.

"We are seeing a rapid increase in interest in Honeywell's total system solution as airport operators become more familiar with our ability to apply DGPS-based technology to practical uses that will increase operating efficiency and safety at their airports," said Mike Smith, vice president and general manager for Honeywell's Business and Commuter Aviation Systems. "The SLS makes good business sense for airports as well as regional operators."

During the past year, Honeywell's SLS flight team successfully demonstrated the capabilities of differential Global Positioning System (DGPS), on which the Honeywell/Pelorus SLS is based, to more than 500 top officials on four continents. Last summer, the team conducted a fice-week demonstration tour of Asia Pacific, visiting nine cities in eight countries and flying more than 240 top-level officials on autopilot-coupled DGPS approaches.

The team demonstrated the SLS at the National Business Aircraft Association Convention in Las Vegas in September, and again in February at the FIDAE '96 Air Show in Santiago, Chile. During April, the team visited seven Eastern and Western European countries in six weeks, demonstrating the system to more than 250 officials.

PROJECT SASKATCHEWAN UPDATE

The Province of Saskatchewan has agreed to purchase five Honeywell/Pelorus SLS for installation at airports in the Province. The first system has been installed at Regina Airport and is scheduled for certification for precision approach service by Transport Canada, this summer. "The Honeywell/Pelorus SLS is accurate, reliable and cost-effective and is ideally suired for airports in Saskatchewan where airservice is essential but passenger volume is light," says Harold Hugg, Director, Saskatchewan Highways and Transportation. "The network of five SLS's will serve multiple runways and airports to enhance operational efficiency and an added measure of safety to aviators in our Province."

PROJECT MINNEAPOLIS UPDATE

Informal flight testing has begun following FAA-approved installation of the Honeywell/Pelorus SLS 2000 at Minneapolis /St. Paul International Airport.

"GPS initiatives represent the greatest leap forward in aviation sice the introduction of the jet engine," said Jeffrey Hamiel, executive director of the Metropolitan Airports Commission (MAC). "The local-area GPS ground station technology transcends other divisive airport issues and provides a springboard for international marketing venues, noise compatibility, airspace management and a variety of capacity issues at about one-third the cost of competing technologies. By providing precise landing guidance for all types of approaches, including "circling approaches," the SLS enables aircraft to avoid long, straight-line paths to runways. This helps decrease the traffic and resulting noise in neighbourhoods in those paths."

The SLS-2000 will serve all runway ends within a radius of 20 to 30 nautical miles at all of MAC's airports. This will give precision approach capability to many of the runways where such approach procedures are currently not available. At the Minneapolis/St. Paul Airport, the SLS-2000 will be able to provide an added level of approach capability because it is designed to be Category II capable with growth to Category III.

PROJECT NEWARK UPDATE

The Honeywell/Pelorus Satellite Landing System (SLS-2000) has been selected for installation and use by Continental Airlines at the Newark International Airport.

Project Newark is being sponsored by the Air Transport Association, and when certified will be the world's first certified DGPS system used for precision approaches in revenue service.

"There is no other instrument approach aid available today that provides greater navigational flexibility and accuracy than the Satellite Landing System," said Jeff Ariens, Continental's GPS Program Director, "The ability to use DGPS for precision approaches can improve Continental's on-time performance, enhance safety, increase savings in fuel expenses, and help reduce air traffic noise, congestion and weather-related delays."

The data collected during Project Newark will be used by the Federal Aviation to help establish certification processes for precision approaches benefiting other air carriers as well as general aviation.

HOW DGPS WORKS

The Satellite Landing System is based on GPS, which provides three-dimensional position information 24 hours a day, anywhere on earth. The SLS-2000 provides a cost-effective way to alleviate airport congestion, air traffic noise and weather-related delays by providing aircraft with very precise navigation data to aid approaches. The result is improved traffic flow and enhanced safety, regardless of weather or terrain.

Three GPS Remote Satellite Measurement Unit (RSMU) antennas are installed at various fixed, surveyed locations in the terminal area. The SLS-2000 ground reference station then compares signals sent from GPS satellites with the true (surveyed) position of the RSMUs to determine errors resulting from atmospheric and other effects. This technique is known as differential GPS.

The appropriate error corrections, plus approach points, are then sent via a DO-217 datalink transmitter to approaching aircraft. The aircraft's onboard GPS equipment uses this data to produce very precise navigation information that is accurate to within 1.5 meters horizontally and 2 meters vertically.

In 1993, Honeywell was the first to certify a "sole means" GPS non-precision approach when the ATR-72 aircraft was certified in Aspen, Colo. The data collected during the Aspen approach certification was used by the FAA and the Satellite Program Office to help establish certification processes for approaches.

Pelorus Navigation Systems has a 14-year track record as a specialist in the design, manufacture, installation and maintenance of ground-based navigation systems. Pelorus has supplied its navigation systems to more than 150 airports on six continents.
