The European Global Navigation Satellite Systems Agency (GSA) has
selected Eutelsat Communications (Paris:ETL) for the development,
integration and operation of the next-generation EGNOS payload on a
future Eutelsat satellite.
Eutelsat and GSA have concluded a long-term contract valued at €102
million covering the preparation and service provision phases for the
EGNOS GEO-3 payload that will be hosted on the EUTELSAT 5 West B
satellite that is due for launch end of 2018. The new payload marks a
replenishment of current EGNOS capacity and is scheduled to start
service in 2019 for a duration of 15 years.
With the addition of the EGNOS payload, Eutelsat is further optimising
the EUTELSAT 5 West B satellite that was commissioned in October 2016 on
a design-to-cost basis from Airbus Defence and Space and Orbital ATK.
Airbus Defence and Space is building the satellite’s commercial Ku-band
payload and the EGNOS payload while the platform is being manufactured
by Orbital ATK.
More on EGNOS
EGNOS is a European Geostationary Navigation Overlay Service that acts
as an augmentation service to Global Positioning Systems to improve the
accuracy and reliability of positioning information. EGNOS also provides
a crucial integrity message regarding the continuity and availability of
a signal which is essential in aviation where GNSS alone does not
satisfy strict operational requirements set by the International Civil
Aviation Organisation (ICAO) for use in critical flight stages such as
final approaches. With the addition of EGNOS, which has been certified
for civil aviation since 2011, systems such as GPS and Galileo can
satisfy ICAO standards. The GSA has been in charge of EGNOS exploitation
How will it work?
The EGNOS GEO-3 payload on EUTELSAT 5 West B will comprise two L-band
transponders that will act as an augmentation, or overlay to GNSS
messages. Data from GNSS measurements received by an interconnected
ground network of positioning stations across Europe will be transferred
to a central computing centre where differential corrections and
integrity messages will be calculated and then broadcast by EUTELSAT 5
West B to users. The new payload will be the first step towards the
deployment of the EGNOS next generation, EGNOS V3. This new generation
of EGNOS will augment both Galileo and GPS and is planned to be
qualified by 2022. EGNOS V3 will provide a higher level of performance
and robustness than the current EGNOS legacy services, as required by
the growing use and reliance on such services.
