European Geostationary Navigation Overlay Service - EGNOS
Europe's primary contribution to GNSS-1 (Global Navigation Satellite System) will
involve signal relay transponders carried on geostationary satellites and a network
of ground stations. Together, they will provide a regional augmentation service
for GPS and GLONASS signals over Europe, the Atlantic and Indian Oceans, South America,
Africa, the Middle East and Central Asia. This augmentation is called an "overlay"
and the European programme is known as the European Geostationary Navigation Overlay
Service, or EGNOS.
Global Navigation Satellite System
During 1999 initial tests have been carried out on the EGNOS Test Bed, and we
were assigned the contract for delivery of the Reference Stations for this system.
The EGNOS Test Bed is based on the SATREF system developed by Kongsberg Maritime
for the Norwegian Network of GPS Reference Stations, and has enabled the EGNOS to
get a "flying start" on the implementation of the Test Bed. This contract is one
of several involvements for us in the GNSS development and is important for the
continued development of advanced, satellite based navigation and positioning products and systems.
