GIOVE on the Line

Europe commenced the space element of its Galileo more than two years ago with launch of the GIOVE-A (Galileo In-Orbit Validation Element-A) demonstration satellite (also known as the Galileo Satellite Test Bed-V2/A).

Call for Papers: International Symposium on GPS/GNSS 2008

Abstracts for the 2008 International Symposium on GPS/GNSS are due on Monday, June 16.

This year, the conference, which rotates throughout the Asia-Pacific region, will take place in Tokyo, Japan from November 11 through November 14.

Presenters who choose to have their papers refereed and published in the proceedings must submit their full papers with payment by July 15. Non-refereed papers must be submitted by September 15.

Authors will be notified of acceptance by July 31.

Envisioning a Future: GNSS System of Systems, Part 3

The radionavigation satellite service (RNSS) portion of the RF spectrum is overcrowded, especially on L1 where GPS, Galileo, Compass overlap portions of one another’s signal frequencies and GLONASS signals occupy more than 11 MHz of nearby bandwidth. Indeed, even those bands that have not been used so far will certainly be shared by many systems in the near future. Therefore, the search of alternative frequency resources is something that must inevitably occur with a high probability in the coming years.

Hope beyond the Hype

A large body of research recognizes personal mobility as the primary future market for global navigation satellite systems in terms of the number of users and potential revenue. This expectation is especially strong for the upcoming European satellite navigation system Galileo, for which location-based service (LBS) applications have a prominent place in market research.

Galileo's GIOVE-B to Launch April 14

The first Galileo experimental satellite, which marked its second anniversary in space on December 28, may soon have company.

Designated the Galileo In-Orbit Validation Element–A (GIOVE-A) satellite, the spacecraft has been broadcasting a variety of signals since January 2006, using on-board rubidium clocks for time-tagging signal transmissions. Now, GIOVE-B — the larger second experimental satellite, which will carry one hydrogen maser and two rubidium clocks, is nearing readiness for transfer to the Russian Baikonur launch facility in Kazakhstan.

MEMS and Platform Orientation & Deep Integration of GNSS/Inertial Systems

Q: How can a GPS receiver or MEMS (micro-electro-mechanical systems) inertial sensor assembly sense a host platform’s orientation? How can these sensor technologies be combined together?

Transport Ministers Put Galileo Back on Track

On Friday (November 30), the European transport council voted unanimously to adopt a European Commission (EC) financial scheme that would lead to a fully operational constellation in 2013, if the project can stay on schedule.

Galileo Open Service and Weak Signal Acquisition

Q: How will the Open Service Galileo signal in space change the acquisition process in GNSS receivers?

A: The Galileo signal in space (SiS) for the Open Service (OS) essentially differs from the GPS C/A-code by its use of the binary offset carrier (BOC) modulation and the adoption of longer spreading codes. Moreover, two different channels have been allocated for the OS: the data and the pilot channels. The former carries the navigation message whereas the latter is data-free.

EU Finance Ministers Approve Galileo Funds

At its November 23 meeting, the European Union’s Economic and Financial Affairs Council (ECONFIN) approved €940 million in supplementary funding during fiscal year 2008 to support a public procurement of the Galileo system.
