In an update to a previous story about plans for GPS and Galileo compatibility, GISDevelopment.net links to a story at Location about a new agreement between the US and the EU for making their respective navigation satellite systems, GPS and Galileo, compatible. From the article: "The European Commission (EC) said a joint working group had overcome technical challenges to design interoperable civil signals. Experts have agreed that a multiplexed binary offset carrier (MBOC) waveform will be used on both systems instead of the binary offset carrier, or BOC (1,1) waveform, as stated in a 1984 agreement between the United States and the EU. The MBOC signal was proposed by a technical working group to examine further refinements to the design.
Future receivers using the MBOC signal should be able to track the GPS and/or Galileo signals with higher accuracy in challenging environments that include multipath, noise, and interference, said the EC."
Galileo is targeted to be operational in 2012.

US GPS and EU Galileo to Work Together 1 comment

Slashdot discuss a Reuters article on the U.S. and Europe trying to reach an agreement to allow using GPS and Galileo signals together. Their summary: "The US and EU are in talks to allow their separate GPS systems to work together. The future uses would allow enhanced location information based on two readings, among other benefits. 'The market probably will drive dual-use receivers. We think probably that single (U.S.) GPS-specific, or Galileo-specific receivers — the market will phase out in time [...] It just doesn't make sense to limit yourself to just one system'." Also from the article: "Under the agreement, which the United States says it expects to be signed this week, both EU and U.S. satellites would send information on the same radio frequency, enabling receivers to get signals from both systems and combine the data." If you read the informative comment on Very Spatial, you'll learn that such GPS-Galileo cooperation was planned from the beginning. See below numerous related stories, including the serious financial troubles of Galileo. Vector One also remarks the new USAF approved 8 GPSIIIa satellites to be launched by 2013.
Galileo's Objectives and Funding 1 comment

Here's a few news regarding the Galileo European satellite navigation system. The SatNav blog questions the objectives of the Galileo program and provide comments following a European Commission communication on Galileo. Related, APB links to an article on the European Commission outlining its plan to get the Galileo satellite navigation system back on track [BBC] and new delays for the second satellite launch. From the BBC article: "This would mean member states having to find about a billion more than they expected because of the collapse of private sector involvement.
The EC is determined to have Galileo operational by the end of 2012.
However, this target is dependent on financing arrangements being put in place this year.
So far, only four spacecraft in the eventual 30-satellite constellation have been ordered. Unless contracts are issued for more platforms in the coming months, the timetable will slip again and Europe's biggest single space project may then face calls to be scrapped altogether."

GALILEO Bad News and GLONASS Good News
[+]
Here's a few recent news regarding GALILEO and GLONASS GPS systems. I copied in related stories below many items of interest regarding the two programs. Recent geoblogs entries include Vector One discussing GALILEO: "Today Christopher Booker of the Telegraph newspaper in the UK sums up the project in his column, “The costs of Galileo have already taken off so wildly (and it is already six years behind schedule), that we may well hand over much more than £1.7 billion to pay for our 17 per cent share in this white elephant (somehow two thirds of the EU’s members have managed to get out of paying anything at all).”" Google's Ed Parsons chimes in. Meanwhile, GLONASS seems in much better shape, as indicated by this other V1 entry and the news of the successful new GLONASS satellite launch.
