GLONASS has "preliminary approval" to transmit CDMA GLONASS signals at L1, L5

GLONASS has gotten “preliminary approval” to add code division multiple access (CDMA) signals to future satellites.

Since its initiation in the early 1980s, the Russian GNSS system has employed frequency division multiple access (FDMA) techniques in which the same code is used for the signals broadcast by the system, with individual spacecraft being distinguished from one another by a specific frequency allocation. Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.

Selective Availability: Completely Dead

Selective Availability (SA), the contentious issue of degrading the open GPS civil to advantage military signals, is going away for good under the terms of a presidential decision announced September 18.

USAF evolves GPS architecture with $800 million upgrade to ground control segment

On September 14, Air Force crews at Schriever AFB, Colorado, completed the initial phase of an $800 million upgrade to the GPS operational control segment.

Operators in the 2nd Space Operations Squadron (2SOPS) of the USAF 50th Space Wing migrated control of the GPS satellite constellation and ground monitoring facilities from a 1970s-era mainframe computer to a distributed IT infrastructure with advanced automated features. The 50th Space Wing, through the 2nd SOPS, performs the satellite command and control mission for the Global Positioning System.

ICG sets up new Providers Forum to pursue compatibility among GNSS systems, augmentation systems

Operators of the world’s four GNSS systems and regional augmentation systems have laid the foundation for a multilateral environment in which to discuss issues of compatibility and interoperability.

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.

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.

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 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).
