7. EGNOS Latest Improvements (I/II)
New EGNOS System Release V2.3.1p was deployed in February-March 2012 with:
GEO Swap (22/3/12): INMARSAT satellite 4F2 (PRN 126) replaced ARTEMIS satellite (PRN 124), thus improving the visibility over the North ECAC area
New reference stations: La Palma (Spain) and Alexandria (Egypt). Athens (Greece) to be deployed in the short term
Improvement in EGNOS functions (iono monitoring)
MT9/MT17 coherency guaranteed
More GPS satellites used by EGNOS (GPS block IIF)
EGNOS performances are currently achieving good values of Navigation Services and thanks to the continuous process for improvement will bring new evolutions and a wider service to EGNOS users.
The new version v2.3.1 to be deployed during 2011 includes the addition of new monitoring stations and the improvement of some EGNOS functions such as IGP monitoring.
One of the main results of this version is the extension of the Service in the border areas as well as the improvement of the robustness in the current one.
Increased service area and improved service robustness in border areas

9. ARTEMIS satellite (PRN 124)
GEO Swap (I/II)
The visibility in the North is improved with the inclusion of PRN126:
ARTEMIS satellite (PRN 124)
INMARSAT satellite 4F2 (PRN 126)
EGNOS performances are currently achieving good values of Navigation Services and thanks to the continuous process for improvement will bring new evolutions and a wider service to EGNOS users.
Date for the P deployment depends on EC, NSA and ESSP.
The new version v2.3.1P to be deployed during 2012 includes the addition of new monitoring stations and the improvement of some EGNOS functions such as IGP monitoring.
One of the main results of this version is the extension of the Service in the border areas as well as the improvement of the robustness in the current one.

10. GEO Swap (II/II) 3 EGNOS Geostationary Satellites
PRN120 Inmarsat AOR-E
PRN124 ESA Artemis
PRN126 Inmarsat IOR-W
EGNOS OPS: PRN120 and PRN126 broadcast EGNOS messages to provide the SIS that is actually used by the EGNOS aviation user
EGNOS TEST: PRN124 is used by industry for EGNOS System Releases tests and operators training and qualification
GEO SWAP: PRN124 replaced by PRN126 in OPS end of March 2012
The current version of the EGNOS system is the ESR 2.2.ext. EGNOS is deployed into two independent systems:
Footprint is not Service Coverage!!
a) EGNOS OPS, this can be considered as the EGNOS System proper as its function is to provide the SIS that is actually computed by the EGNOS user. It comprises the following assets: 33 RIMS (Ranging and Integrity Monitoring Stations) , 3 Central Processing Facilities , 3 Mission Control Centers , 2 GEOS: Inmarsat AOR-E (PRN120) and ESA ARTEMIS (PRN124), 4 Navigation Land Earth Stations
b) EGNOS TEST. Its mission is to provide the necessary platform to the industry to develop, test and validate new system evolutions (software, algorithms, new RIMS, etc.) prior to their implementation on EGNOS OPS. It is also used by ESSP for the training and qualification of the operators. It comprises the following assets: 1 RIMS (in Kourou). At the time of writing this paper (May 2010) three new RIMS (La Palma, Alexandria and Athens) are running on EGNOS TEST, in view of their integration in OPS. Additionally, four new RIMS are being or will be deployed in the near future (Agadir, Tamanrasset, Abu Simbel and Tel Aviv). 2 Central Processing Facilities (in Langen and Ciampino) , 1 Mission Control Center , 1 GEO currently Inmarsat IOR-W (PRN 126) , 2 Navigation Land Earth Stations

11. EGNOS future improvements
APV-I target service area 2014
ESR V2.3.1i: Summer 2012.
The Industry is working in the development of a new EGNOS system release more robust to ionospheric disturbances.
It is expected that this new release will be deployed in Summer 2012.
ESR V2.3.2 and V2.4.x:
Improvement of Ionospheric monitoring
LPV-200 service
Addition of new RIMS (up to 40)
Next generation infrastructure (New GEOs, improved comm network, etc.)
APV I target Service Area in 2014…

17. EGNOS SoL Service (III/III)
Service Notices are available at ESSP website:
Service Notices published so far:
Service Notice #1: MT9-MT17 Status (NOT APPLICABLE after deployment of ESR2.3.1P)
Service Notice #2: Status of EGNOS performances (updated in April 2012!)
Service Notice #3: EGNOS upgrades deployed in Q1 of 2012 (updated in April 2012!)

18. EGNOS SoL Service Degradation (SN#2)
SoL Service degradation since Sept 2011 affecting APV-I availability mainly in SW and N of Service Area but:
Not compromising integrity at any moment
Not affecting OS users
Not affecting NPA users
Limited impact in published LPV procedures
Investigations showed that it was related to:
Several NANUs on GPS SVs together with new generation GPS satellites (GPS-IIF) out of the EGNOS mask lowering the number of satellites available.
Solar activity increase degrading the ionospheric monitoring capability of the system.
02/07/2012
ICAO PBN TF7

19. EGNOS SoL Service Degradation (SN#2)
Mitigation actions applied
Issue given highest priority by ESSP, EC, ESA and industry.
EGNOS mask updated in February 2012 to include GPS-IIF SVs (PRN1&25) plus PRN27
Operational workaround applied
ESR231p in February 2012 already correcting some iono related issues and improving robustness thanks to additional RIMS
02/07/2012
ICAO PBN TF7

20. EGNOS SoL Service Degradation (SN#2)
Service Degradation Current Status:
Contingency situation not existing anymore
EGNOS performance back to nominal levels since May mainly due to:
Effectiveness of Operational Work Around
ESR231p improvements (iono robustness, new RIMS and new GPS satellites Block IIF)
Moderation of solar activity
Additional robustness against iono activity is expected by August 2012 with ESR231i

21. Leap Second introduction (SN#4)
International Earth Rotation and Reference Systems Service (IERS) add a leap second to the UTC, when required, in order to align this reference with the Mean Solar Time
The process to manage the introduction of a new leap second in EGNOS was concluded that could imply an EGNOS service (OS and SoL) unavailability during a period of 72 hours starting from July the 1st at 00:00:00 CET.
SN #4 was published to inform on this planned service outage.
EWA specific communications issued and NOTAMs generated to inform final users accordingly
No service outage was finally caused.
SN #4 updated on 30/06/12 accordingly.
All related NOTAMs were cancelled
