Report on Galileo System
CPGPS has filed a report regarding
Galileo navigation system. Dr. Chen Wu and Ruizhi Chen are invitied as
co-editors for this report. This report will summarize the following topics:
Part 1: Galileo System including
Galileo Architecture, Galileo services- governmental and legal issues,
Galileo Signals and Frequency of services, Galileo Vs GPS: technological
and application advantages
Part 2: Key Technologies
(to be developed for China), including Options for China¡¯s Participation
in Galileo program, Near Real Time GPS/Galileo Orbit Determination and
Services, Regional Ground Integrity Monitoring (GIM) services (GPS+Galileo,
with interface to Galileo system, a local element, Real time regional wide
area differential positioning (nationwide), TCAR ?based Local RTK, Advanced
Galileo/GPS receiver technologies, Communication Technologies for Navigation
and Positioning Services, Receiver Autonomous Integrity Monitoring, and
Local area augmentation systems for landing.
Part3: Major applications
(Galileo, and Galileo+GPS, shall compare with GPS only) including Space
Engineering, Civil aviation applications, Railway applications, Geodesy
and geophysics, Road vehicle navigations, Space applications (weather,
occultation, gravity), Ground-based meteorology, and Monitoring/crustal
deformations, continuous operating systems.
Part 4: Social and economic
aspects, including China¡¯s national interests and Galileo program, Markets
and economic benefits, Security issues and solutions, and Galileo Education
Successful
Launch of the 3rd Chinese Beidou Navigation Satellite
China has successful launched the
3rd Chinese Beidou Navigation Satellite, the detailed information can be

Dr.
Wang¡¯s Publication in GPS World
In the most recent GPS world, Dr.
Wang Jin and his co-author published an interesting article regarding KGPS/INS
performance and reliability. GPS World has quite wider readership. CPGPS
encourages her members to publish as many papers as you can in the international
well-known magazines and journals.
GWG
Working Group
Recently Dr. FengYanming
at QUT, Australia, is leading an effort to participate and contribute to
the GALILEO program where some Chinese state agencies and academic institutions
begin to be involved. The current collaborative team member include
Prof C. K. Shum
Dr Peng Fang
Dr Yang Gao
Dr Shaowei Han
Dr Wu Chen
Dr Ruizhi Chen
Dr Jinling Wang
Dr Weiping Jiang
Dr Yanming Feng
We believe that the expertise of
our members can significantly benefit the related projects. This special
working group will deploy a series of work in the near future.
Europe
Navigation Satellite: Galileo
The European Space Agency is now
able to finalise the conditions for participation in the Galileo
navigation programme and to approve the Galileo Joint Undertaking foundation
act to be soon signed by ESA and the European Union. The agreement
reached among ESA member states today clears the way for the official launch
of the legal entity which will have the task of coordinating ESA and EU
involvement in Galileo, the European initiative to develop a global satellite
navigation system.
"This is a great day for Europe
in general and its space community in particular. Conscious of the economic,
industrial and strategic importance of satellite navigation, our Member
States have reached agreement in the common interest. We are now able to
continue with Galileo, a major programme from which all citizens will benefit.
Galileo is definitely a reality", said Antonio Rodot¨¤, ESA Director General
at the end of the Council Meeting at Delegate level held in Paris today
while informing German Minister of Education and Research, Mrs. Edelgard
Bulmahn, Chairwoman of the ESA Council at Ministerial level to be held
in Paris tomorrow.
"I am extremely delighted with this
result. Galileo is now on its way . I am grateful to all ESA Member States
that have striven to find a balanced solution and pleased that Europe has
once again proven to be able to remain at the forefront of high level technology
for a programme useful to each of us in our everyday life" said Mrs. Bulmahn
when she heard the good news.
The Galileo Joint Undertaking, to
be headquartered in Brussels, has a key part to play in implementing the
various phases of the programme. This unique organisational structure will
pave the way for the entity that will in due course operate the Galileo
system. It will be responsible for the Galileo development and validation
phase and also for preparations for system deployment and operations. The
founding members of the Galileo Joint Undertaking are the European Space
Agency and the European Union, represented by the European Commission.
Galileo will complement the existing
satellite navigation system, which presently relies entirely on GPS, the
American Global Positioning System. Developed by ESA and the EU on the
basis of equal co-funding, Galileo is designed to provide a complete civil
system. Scheduled to be operational by 2008, it will offer the citizens
of Europe and the world an accurate and secure satellite positioning capability.
A broad range of applications will be supported by the system : control
of road, rail and sea traffic, synchronised data transmission between computers,
and many others. Projections point to very significant economic benefits,
with a return on investment of 4.6 and creation of over 140 000 jobs.
Galileo is the first instance of
a project carried out jointly by the European Space Agency and the European
Union. The Galileo system will be built around 30 satellites (27 operational
and 3 reserve craft) occupying three circular earth orbits, inclined at
56¡ã to the Equator, at an altitude of 23 616 km. This configuration will
provide excellent coverage of the planet. Two Galileo control centres will
be established in Europe to control satellite operations and manage the
navigation system. (ESA PRESS RELEASE)
