It’s MBOC for common Galileo-GPS civil signal

The United States and the European Union (EU) have agreed to use the multiplexed binary offset carrier (MBOC) for a common GPS-Galileo signal for civilian use. In the future, this will enable combined GNSS receivers to track the GPS and Galileo signals with higher accuracy, even in challenging environments that include multipath, noise, and interference.

These signals will be implemented on the Galileo Open Service and the GPS IIIA new L1 civil signal known as L1C.

Proton launch failure raises questions about timeline for completing GLONASS constellation

The September 6 crash of a Russian Proton-M rocket carrying a Japanese telecommunications satellite (JCSAT 11) has injected an element of uncertainty into plans for completing the GLONASS constellation.

Russia’s Baikonur cosmodrome automatically suspended all Proton rocket flights, pending an investigation, after the failure of the rocket, which crashed in the steppes of Kazakhstan just over two minutes after lift-off. Russia rents the space facility from Kazakhstan, a former republic in the USSR.

U.S. Air Force Releases GPS Block IIIA Satellite RFP

After several false starts in the previous months and a multi-year delay in the overall GPS III architecture development, the GPS Wing (formerly the GPS Joint Program Office) announced on July 12 the release of a request for proposal for the development and production of the GPS Block IIIA satellites.

Galileo’s New PPP: Public-Public Partnership?

Having abandoned — for the time being at least — attempts to attract private investment to the creation of Galileo’s infrastructure, European GNSS leaders are working to shape a Plan B that can gain support from the program’s extensive group of stakeholders.

Galileo’s Plan B (and C)

A sea change appears to be taking place in Europe’s Galileo program as its political masters prepare to transform the struggling public-private partnership (PPP) into a more traditional institutional program wholly sponsored by the public sector.

That would move an additional €2.4 to €3 billion onto the public tax burden, but it might also represent the quickest route to completion of the GNSS project backed by the European Union (EU) and the European Space Agency (ESA).

Galileo Plods On

Europe’s Galileo program continues to take small steps as it waits to see if it can get through an impasse between the European Commission (EC) and the consortium of companies seeking a concession to complete and operate the Galileo system.

More Perils for Galileo . . . and Other GNSS Dramas

A convergence of developments over the past few months has brought Europe’s Galileo program to the most critical passage of its history — at least, since final approval of the GNSS initiative by the European Space Agency (ESA) and the European Union (EU) in 2003 and 2004, respectively.

GPS Block III Contracts

The U.S. Air Force has awarded two $50 million contracts to Boeing and Lockheed Martin to execute a system design review for the next-generation GPS space segment program, GPS Block III.

The contracts come on the heels of both companies successfully completing system requirements reviews in November 2006. Those reviews, part of a $10 million follow-on order to a Phase A Concept Development Contract awarded in 2004, assessed Boeing’s and Lockheed’s ability to mitigate development and delivery risks associated with building the Block III satellites.
