The EGNOS User Interface Document Explained 2nd EGNOS Receiver Workshop 30th Sept 2005, ESTEC, Noordwijk, The Netherlands Javier Ventura-Traveset European Space Agency, EGNOS Project Office Patricia Yague -- European Space Agency, EGNOS Project Office Cristoforo Montefusco ENAV, Italy
Presentation overview Reasons for the EGNOS UID Structure and contents of the document Schedule Disclaimer Conclusions
Reasons for the EGNOS UID Provide a high level information document for users, application developers, receiver manufacturers, institutions interested in EGNOS and satellite navigation explain how to access the EGNOS SIS, how the system works, what is delivered to users and how the system will evolve. It is a living document issued by ESA that will accompany EGNOS through its life, providing official information on the system like: SIS and architecture description, performance, compliance with standards and planned evolutions.

Schedule for the EGNOS UID A first issue of 60 pages has been produced in 2004 but not delivered An ESA/GJU review took place in July 2004 In January 2005 a second ESA/GJU took place. EGNOS UID will be public available by November 2005 (TBC) This document will be updated whenever EGNOS improvements are implemented and more knowledge on performance is available. 1 st ESA/GJU Review 2 nd ESA/GJU Review Release JAN 04 JUL 04 JAN 05 NOV 05 (TBC)
Conclusion EGNOS UID will provide the navigation community a reference EGNOS document Planned to be ready in November 2005 (TBC), will be a public document available for download on the web sites: http://www.esa.int/egnos http://www.esa.int/navigation/egnos-pro Users, receiver manufacturers, application developers, institutions and organisations interested in EGNOS and satellite navigations will certainly benefit of this EGNOS UID, therefore they are invited to contribute. Let us know the: subjects/explanations/pictures you would like to see in the documents and contact us via e-mail at: egnos@esa.int indicating in the subject: EGNOS UID suggestion, we will appreciate it a lot!
