What is EGNOS?

 EGNOS =

European Geostationary Navigation Overlay Service

 EGNOS is the European Satellite Base Augmentation System (SBAS)  EGNOS “augment” the GPS L1 signal 

Accuracy

of positioning is improved up to 1 and 2 meters 

Integrity

and safety is improved by broadcasting alerts within a few seconds of the occurrence of a failure in GPS and by providing a level of confidence on the position computation with EGNOS

EGNOS Signal-In-Space Message Type 0

 

Message Type 0

(Don't Use for Safety Applications message)

 Message currently transmitted by the EGNOS Signal in Space

When the Message Type 0 is on

,

EGNOS can not be used

for Safety of Life applications and therefore is not usable

for aviation

EGNOS Performances

EGNOS Performances

   EGNOS has been designed to meet stringent requirements coming from

Aviation ICAO SARPS

    Accuracy Availability Continuity Integrity define performances in terms of For given aeronautical operations such as

APV-1

(Approach Operations with Vertical Guidance), specific performances are defined 22

Signal In Space Availability

 Over last year, the reception percentage of EGNOS signal (at least one SIS GEO operational ) was 99.999% 23

Accuracy

 The Horizontal/Vertical (HNSE<

3m

and VNSE<

4m

) Navigation System has always been Error above 99% for each month of the last year HPE on a day HPE distribution on a year 24

APV-1 Availability(99%) over ECAC

99% isoline 25

EGNOS Performances

 Current EGNOS V2.2ext achieving good levels of performance toward Aviation ICAO SARPS  New EGNOS V2.3.1 (in 2011) with  New RIMS stations (at least 4)  Improvement EGNOS functions  improve the service area and the service robutness in service border area 26

APV-1 Availability Extension (2011)

99% isoline 27

Other EGNOS Applications

 Thanks to the accuracy improvement of the EGNOS, many other users could benefit from EGNOS for a wide range of applications :  Agriculture users could reduce the usage of fertilizers, reduce costs and help the environment  Maritime users can profit from the better accuracy for harbor navigation or inland navigation  Terrestrial users tracking system can benefit from enhanced

ESSP Certification

The need of Certification

   To provide the SoL Service for Aviation, ESSP has to be certified according to the

Single Europen Sky (SES)

regulation The Certification process is being managed with the

French National Supervisory Authority

(NSA) and under SES framework will be accepted by all other EU member’s NSAs French

NSA

proposed to associate 7 other states : Belgium, Germany, Italy, Portugal, Spain, Switzerland, United Kingdom

Certification Framework (Applicable Regulations)

Safe Introduction of the Service    The SES regulation requires proving that any change to the current services is safe.

introduction of EGNOS in Air Traffic Management (or Initial Change) requires a

Safety Case

 To demonstrate that the introduction of this service is safe Safety Case change “0”  particularly on the removal of MT0 from the EGNOS Signal in Space  Demonstrate that will not pose a risk to the users currently conducting other GNSS based procedures (GPS NPA for example)

EGNOS Safety-Of-Live Service

EGNOS SoL Service implementation

 ESSP as a provider of the EGNOS SoL Service is based on: 1.

2.

ESSP Certification as ANSP and EGNOS system verification Service agreements between the ESSP and the different European Air Navigation Service Providers (ANSPs)

EGNOS SoL Service implementation



ESSP Certification as an ANSP

 Expected to be obtained in July 2010 

EGNOS Declaration of Verification

 To be issued in July 2010 (just after being certified as ANSP) 

MT0 OFF (& observation period)

 Expected to be removed in August 2010 

SoL Service Declaration

 To be issued in October/ November 2010 35

EGNOS SoL Service implementation

 The Declaration of SoL Service by the EC is just the first step in the service provison to the final civil aviation user  National ANSPs  have to develop, submit to the NSA for approval and publish flight procedures based in EGNOS  Agree a service agreement with the ESSP  Service Definition Document  will state the conditions of access and the service performance commitments

EGNOS SoL: WHY ? Civil Aviation GNSS strategy



11th ICAO ANC (2003):

Aviation approach for GNSS: Final Objective: If GNSS is the better solution with regard to safety and cost/benefit, it should be used as “unique navigation means” for all phases of flight.  

Advantages of EGNOS for Aviation

 EGNOS Safety-of-Life Service is an enabler for Approach with Vertical Guidance (APV) and provides both, lateral and vertical guidance , with the following identified benefits:  Reduce decision height Minima :  APV SBAS (GPS + EGNOS): 250 ft  Safety increase by providing Precision Approach (NPA)).

vertical guidance during approach (statistics show that a high proportion of accidents due to Controlled Flight Into Terrain (CFIT) occur during Non  Increased accessibility with lower minima , making landings possible with lower visibility levels at airports not already equipped with ILS or during ILS outages.

 More flexibility in procedure design :  Curved/segmented precision approaches possible with time and fuel savings, and environmental benefits from reduced noise impact and avoidance of high-density populated areas during approach.

 Possibility to exploit different approach angles for wake-vortex avoidance.

 Limited impact on user avionics :  Software upgrade of avionics receiver. Receivers are currently available.

  Utilization of the same frequency as GPS.

Limited impact on the Flight Management System (FMS) related to the enabling of APV operations.
