Generally, this is not an area that the IGS or IAG are concerned with, however, this relates to continued advocacy of an 'open data policy' and should be reaffirmed by our communities as a unified approach. Here is what is happening: ------------------------------------------- With the development of the Galileo Programme business model, a study is underway to explore and analyze the impact of cost allocations of GNSS, specifically, how legally and technically Galileo/EC can recover costs for CNS/ATM (Communications, Navigation, Surveillance/Air Traffic Management) at regional levels. This is an agenda item being addressed now by ICAO (International Civil Aviation Organization) at their meeting in Montreal (Sep 28 - Oct 8, 2004). A similar agenda item proposes a resolution countering this position, which comes from IATA (International Air Transport Association) "The IATA member airlines recognize the importance Satellite Navigation will play in the development of the CNS/ATM development and the benefits it can bring to the aviation community as a whole. However political or specific geographical economic interests could significantly hinder the early usage of presently available services and might lead to an undesired increase of ANS infrastructure costs." Further stated: "2.3. The aviation community, operating globally, but subject to the sovereign requirements of the States through which they operate, can be easily targeted as a potential source of financing, forced by State legislation to use and or pay for a specific service to operate within a specific airspace where other adequate freely available services are in place." -------------------------------------------- An important reason to bring this to your attention is that for the scientific and technical communities of IAG/IGS, the long term availability of GNSS is critical for our diverse activities, observations, and research. Galileo is certainly a welcome addition to GPS and GLONASS, forming a truly multi-service GNSS in the future. It is not clear at present how cost allocations may be implemented, and what impact such mechanisms might have on our ability to utilize Galileo. As noted in the International Union of Geodesy and Geophysics (IUGG) Resolution 10, July 2003 (below), you are encouraged to engage in activities to ensure long term availability of these satellite signals -- express your support for a policy of openly available data and information. with regards, Ruth Neilan ------------------------------------------------------------------------------------------------------- http://www.iugg.org/eres.html July 2003 Resolution 10: Inter-operability and Protection of Global Navigation Satellite System signals The International Union of Geodesy and Geophysics, Noting, 1. The extensive use of the Global Positioning System (GPS) over the past decade, the highly successful integrated receiver and analysis experience in combining GPS and GLONASS observations, and incredible potential of combining multiple Global Navigations Satellite Systems (GNSS), anticipated by the addition of European GNSS Galileo; and 2. The GPS/GNSS modernization program features three civil signals, and, 3. The broad user base of the GPS/GNSS system within IUGG and sister organizations as a tool for science, multidisciplinary applications and societal benefits. Recognizes, The need to foster and protect GNSS systems; and Recommends, 1. That GNSS providers are strongly encouraged to cooperate and coordinate closely to ensure inter-operability and compatibility in developing, deploying and operating seamless systems now and in the future and to maximize common frequencies and signals; and 2. That scientists in IUGG and sister organizations are encouraged to engage in continual activities to protect the signal and spectrum of collective GNSS, to secure long term availability of these satellite signals available from present and future GNSS systems. -- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ International GPS Service - Central Bureau Jet Propulsion Laboratory tel: 818-354-8330, fax: 818-393-6686 mobile: 626-975-1136 http://igscb.jpl.nasa.gov ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
