1. 1 Discussion Item: New Satellite System Do we need (new) standards? NexSAT Steering Group 9th March 2006, Toulouse European Organisation for the Safety of Air Navigation

3. 3 ECTL FCI: A scenario for 2020 New Terrestrial System(s) Satellite System A Satellite System B VHF

4. 4 SwiftBroadband Feasibility Study: WP2 - Competitive Issues The report maintains that competition is necessary and good. however where competition exists… Interoperability is essential! Means to ensure interoperability Acceptability Criteria AMS(R)S SARPS Technical Manual The pragmatic approach….. ANSPs should make that the job of their service provider!

5. 5 Discussion Thoughts - Points Interoperability – Internetworking What are the means to ensure interoperability? What is the emerging common vision (assuming there is one)? Can we envisage (in the future) different satellite payload operated/owned by different entities (commercial and/or public) supporting transparent to the user global coverage? Are the new generic SARPs sufficient? Do we need something else? Minimum boxes? Who pays for the development of a standard?
