Why thinking of EGNOS second Generation (V3)?

• EGNOS V3 will provide the Galileo SoL• International context is evolving:

− New GPS frequencies (GPS L2C, L5)− Some existing frequencies will disappear(GPS L2 P(Y)) (confirmed

by US Gov) − New constellations are being developed− Other SBAS are coming or planned to be modernized (IWG)

• This new context opens the door for improved services (e.g. robust LPV200), CAT1 (10m VAL), coverage extension towards SBAS multiregional global coverage)

• Multi-constellation GNSS for major Airlines (commercial aviation AIRBUS – BOEING) with a quasi – global coverage required in 2020-2025

• European Industry need to be maintained at the edge of GNSS technology

Dual Frequency Dual GNSS SBAS and International SBAS coordination

EGNOS V3 will be based on Dual Frequency Dual constellation (GPS & Galileo). It will be interoperable with other SBASThe international Standard for the second generation of SBAS is under preparation and coordinated at IWG level (5 SBAS providers meeting twice a year)

Global SBAS Status presentation updated regularly and available on web sites of SBAS providers

INTRODUCTION

Assesses feasibility and interest of foreseen features

• Multi-frequency• Multi-constellation

• Extension of service area

• Areas of improvement on top of EGNOS V2 system

Through 5 set of experimentations

Part of “European GNSS Evolution Program”, phase 2 A laboratory for future EGNOS services dedicated to

aeronautical users

Cycle 1a Mono-frequency and mono-constellation users – RIMS / CPF functional allocations

Cycle 1b Mono-frequency and mono-constellation users – UDRE improvements and extension to Africa

Cycle 2a Dual-frequency users (GPS only and GPS / GLONASS)

Cycle 2b Dual-frequency GPS / GALILEO users

GATE User integrity advanced concept (Advanced RAIM) Real time demo. of dual-frequency GPS / Galileo users

2013 EGEP/EGNOS achievements

These results using simulated data shows that in opposition to the GPS/GLONASS (FDMA) configuration (as experimented in the previous Cycle 2a), the GPS/Galileo CAT1 Autoland (10 m Vertical Alert Limit) availability performance is reaching the required 99% on the ensemble of the service area (as applicable for the EGNOS V3 study). This prefigures the expected operational performance benefits for a dual frequency EGNOS/GPS/Galileo user as compared to the current 99% APV1 / LPV200

service (50m/ 35 m Vertical Alert Limit) .

System test beds to support V3

ARCTIC Testbed

• Specific SBAS issues related to ARCTIC region:

− Maritime market− Representative user

equipment− Alternative dissemination

means enabling better extension than GEO

− Extension of Ground Station network

− Interoperability− Nominal & degraded

IONO/scintillation monitoring

− Improved IONO handling for the region
