Evolutionary development. “ .. incremental path toward
meeting market and user needs rather than attempting to
satisfy all needs in a single step. This provided program
managers with more achievable requirements, which, in
turn, facilitated shorter cycle times. ..”

Network Migration (G1 to G2)
ESA UNCLASSIFIED – For Official Use
Requirements
1. Programmatic context:
1. Existing EGNOS Network Technology Obsolete with a
deadline imposed by BT of early 2014
2. Necessity to migrate on time in order to avoid risk to service
availability and/or considerable cost impacts
2. Initial trade-off between approaches:
1. Migrate with Notice to Users with a Service Interruption
2. Migrate without Service Interruption (Continued Service) :
Chosen Option
3. Migration high level requirements:
−
service at least as good as current service
−
Migrate without Service Interruption (Continuous service)
−
Migrate without risk on Integrity

VPN1 to VPN2 Migration
Before migration situation :
- RIMS attached to one MCC (FR before 2.3.1)
- MCC interconnected with IPLC.
- NLES connected through IPLC network.
- VSAT (C, Ku) partially redundant
After migration situation :
- RIMS (MPLS) attached to ALL MCC.
- MCC interconnected with MPLS.
- NLES connected through MPLS.
- VSAT C band only fully redundant
Full MPLS Network with added
redundancy.
D/NAV/ER | Slide 13
Original Situation.
During migration :
- Deployment of a second MPLS network.
- Connection of each RIMS to the network (Raw data only).
- Independence of the networks (For safety reasons).
- Testing of EGNOS on the new network independently of EGNOS in operation.
D/NAV/ER | Slide 14
EGNOS Migrated to the new VPN.
Results : 10 days encompassing the
operational migration executed by
ESSP

• Continue R&D (EGEP / H2020)
• Preparation of the CD Phase of EGNOS V3
• Transition to new framework (Working arrangement with
GSA)
D/NAV/ER | Slide 17
Conclusion
• Major successes in 2013 (V2 Evolutions, V3 SRR, EGEP
results)
• Ambitious program of work (on both V2 and V3) for next 8
years
• 2014 is the year to transition to new framework for 20142020 (GSA, new working arrangement)
• International momentum around SBAS still growing
• Cooperation between ESA & ASECNA has started (MOU for
Ionospheric data collection & processing)
