Australia’s Earth Science and Geodetic community are proposing to
improve the nations Geospatial Reference System by enhancing the
country’s geodetic infrastructure. The proposed expansion includes
several VLBI / SLR sites and the establishment of 100 plus GNSS CORS
network across the continent. Such infrastructure will facilitate
scientists and researchers to gain a better understanding of the
Australian continent ; support positioning applications ; contribute
significantly to the enhancement of the ITRF ; and subsequently improve
the accuracy of the geospatial reference system that underpins the
Australian society’s fundamental datasets and economic activity.

The Swedish Network of Permanent GNSS stations, SWEPOS™ has now
exceeded 100 stations and is still growing! SWEPOS is a national network
of permanent reference stations for GPS. The purpose of SWEPOS is to
provide data from the GPS and GLONASS satellites for several
applications - from real-time positioning with metre accuracy for, among
other things, navigation and data collection for geographic databases
and to study crustal movements of the Earth with millimetre accuracy.
Development work is currently underway to provide RTK services based on
SWEPOS in some regions of Sweden. The network concept is used for these
services and testing of available software in the market is in progress.
SWEPOS data is provided for post-processing via an FTP server. It is
also possible to submit a file with observation data in RINEX format on
the SWEPOS web site and obtain coordinates for the observation site
together with quality parameters. The network consists of 21 core
stations and the remainder are dedicated Network-RTK stations and these
are considered simplified stations. For more information, please go to

ITRF2005 is expected to be available during the summer 2006 according
to Zuheir Altamimi, France. ITRF2005 is the new solution following the
previous ITRF2000. The solution will be available at
http://itrf.ensg.ign.fr/ as well
as information about the computation of it. Unlike the previous ITRF
solutions, ITRF2005 will be based on the combination of time series of
station positions and EOPs. The latter should cover as long a time
interval as possible but at least 6 years (say 1999-2004), a period over
which we expect to have solutions containing EOPs from all the
techniques. This new ITRF solution will include all available data for
station positions, such as for instance VLBI and SLR data since the
eighties. Weekly or (daily VLBI) solutions will allow better monitoring
of non-linear motions of stations and other kind of discontinuities in
the time series.
