HONEYWELL IS TO install a satellite-based landing-system at Moscow's Zhukovsky airfield for use by Russia's Department of Air Transportation to establish certification and operational procedures for precision approaches using the global-positioning system (GPS) and its Russian equivalent, GLONASS.
The US company will supply its SLS-2000 differential-GPS (DGPS) ground station, which has been sold to airports in Australia, Canada and the USA. This uses three remote GPS reference-receivers and multiple differential-correction processors to calculate positioning errors and perform integrity checks before transmitting (DGPS) corrections to incoming aircraft via a VHF datalink.
Honeywell says that Special Category I certification of the SLS-2000 is expected at Minneapolis/St Paul, New York's Newark Airport and Regina in Saskatchewan, Canada, in the first quarter of 1996.
The Minneapolis system will serve all runway ends within a 32-48km (17-26nm) radius at all of the metropolitan-area airports, the company says.
Honeywell has introduced the VL-2000 airborne VHF datalink receiver, designed for use with the DO-217 datalink specified for local-area DGPS systems. The VL-2000 will receive up-linked differential corrections and approach co-ordinates from a DGPS ground-station and route the information to the onboard GPS receiver.
Honeywell is also adding GPS functionality as standard fit to the flight-management system it produces for the Fokker 70 and 100 twinjets. The added GPS capability will allow the aircraft to fly new routes and altitudes under the Euronav and Future Air Navigation System air-traffic management systems, and will be certificated on both types around mid-1996.
