NASA Orders Two Honeywell/Pelorus Satellite Landing Systems for Use with Shuttle Training Aircraft Program

Business Wire, June 18, 1997

CALGARY, ALBERTA--(BUSINESS WIRE)--June 18, 1997--(Alberta Stock Exchange PN. ) Honeywell Inc. announced at the Paris Airshow that NASA has received two Honeywell / Pelorus Satellite Landing Systems for use with its Shuttle Training Aircraft (STA) at two domestic locations.

NASA has chosen the SLS-1000 system for astronaut training support, flight testing and data collection at White Sands Space Harbour, N.M. The SLS-2000 Satellite Landing System will be installed at the Kennedy Space Center, Fla., to provide precise differential Global Positioning System (DGPS) navigational capability to the Shuttle Landing Facility.

The order represents the first U.S. government purchase of the Honeywell/ Pelorus Satellite Landing System, which is nearing Federal Aviation Administration certification at Minneapolis/St. Paul (KMSP) and Newark, N.J. (KEWR) international airports. In addition, Honeywell/Pelorus systems are installed at Regina and Saskatoon airports in Canada. The Honeywell/ Pelorus system is expected to be the world's first certified DGPS system when it receives Special Category 1 certification from the Federal Aviation Administration and Transport Canada.

Honeywell/Pelorus SLS systems have also been delivered to the U.S. navy and U.S. airforce.

Honeywell / Pelorus Satellite Landing System

--------------------------------------------

The SLS-1000 and SLS-2000 serve all runway ends within a radius of 20 to 30 nautical miles. This gives precision approach capability to many runways where such approach procedures are currently not available.

The SLS is comprised of GPS Remote Satellite Measurement Unit (RSMU) antennae a ground reference processor and VHF antenna. The RSMU's are installed at various fixed, surveyed locations in the terminal area. The SLS ground reference station then compares signals sent from GPS satellites with the true (surveyed) position of the RSMU's to determine errors resulting from atmospheric and other effects. This technique is known as differential GPS.

The appropriate error corrections, plus approach paths, are then sent via a DO-217 datalink transmitter to approaching aircraft. The aircraft's onboard GPS equipment uses this data to construct an Instrument Landing System (ILS) look-alike approach path that directs the flight controls and displays for precision approach.

The SLS-2000's fail-operational architecture allows for continued operation in the presence of faults with less hardware than traditional systems, reducing the cost of ownership and maintenance.

Honeywell/Pelorus History

In January, 1995, Honeywell Inc. of the United States and Pelorus Navigation Systems Inc. of Canada entered into an exclusive teaming agreement to design, manufacture, install and maintain a Satellite landing System for sole means precision approach and landing.

Pelorus Navigation Systems Inc., Honeywell's partner in the design, manufacture and installation of the SLS ground station has a 14 year track record as a specialist in ground- based navigation systems. Pelorus has supplied navigation systems to more than 150 airports worldwide.

Honeywell is a global controls company providing products, systems and services that increase comfort, environmental protection, energy conservation, productivity and safety in homes and buildings, industry, and aviation and space. The company employs 53,000 people in 95 countries on six continents and had 1996 sales of U.S. $7.3 billion.
