[11-21-07 – Satellite Today] Park Air Systems, a subsidiary of Northrop Grumman Corp., has developed and installed the ground-based elements of a global navigation system for Bronnoysund Airport, in Norway, Northrop Grumman announced Nov. 21.
    The NORMARC 8005 SCAT-I ground station receives and validates GPS signals and then transmits the calculated signal corrections and flight path data via a VHF data link. SCAT-I avionics uses the received signal to improve position accuracy and signal integrity along a defined flight path. One ground station can serve several approaches for both ends of the runway.
    "The system is ideally suited for use in airports where, due to the geographical conditions, it is not economically feasible to install a conventional instrument landing system,” said Cato Engebretson, director of navigation systems at Park Air Systems in Norway. “This technology development will help improve safety particularly at the smaller regional airports in Norway.”
