Dear colleagues,
I am passing some information on to you concerning GNSS cost
allocations with respect to civil aviation. 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

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.
