6. Development Priorities  Standards  RTCM NTRIP(transport), MSM(data), SSR(products); ITRF  Orbits and Clocks:  Physical Models (APC, Solar radiation, satellite attitude…)  Atmospheric Delays:  Regional Ionosphere and Troposphere  Equipment Biases  Inter-frequency code and carrier delays  Solution Parametrization  Integer ambiguity fixing Question: What is the priority?

7. Service Offering  Public sector:  Regulatory role  Responsible for safety  Continuity and traceability to standard  Commercial:  Market driven  Targeted applications  Customized solutions Question: Connect at what level: Reference Frame, GNSS Data, Products?

8. For Discussion: My Choices  Constellations and Signals: Be Selective  Minimize risk  Global Tracking: Densify  Demonstrate reliability  Development Priority – Regional Ionosphere  Accelerate convergence  Offering – Public and Private  Synergy and Complementary
