Galileo’s Drama: Different Set, Additional Actors, a New Play for Europe’s GNSS?

Passage of a new regulation on Galileo sets the stage for the next phase of the €3.4-billion satellite navigation system’s development under a public procurement but leaves many details to be worked out among the key players: the European Commission (EC), the European Council, the European Parliament, and the European Space Agency (ESA).

Meeting in Strasbourg, France, the parliament adopted the measure on April 22 with 607 votes in favor, 36 votes against, and 8 abstentions.

“Things are looking up, finally, for the European GNSS programs,” Paul Verhoef, head of the Galileo unit in the EC’s Directorate-General for Transport and Energy, told an April 23 plenary session of the European Navigation Conference 2008 in Toulouse, France.

Russia Approves CDMA Signals for GLONASS, Discussing Common Signal Design

Nearly 30 years after the first launch of a GLONASS spacecraft, Russia is moving to add code division multiple access (CDMA) signals to the frequency division multiple access (FDMA) format that has set the world’s second-oldest global satellite navigation system apart from GPS and other systems under development.

A February 15, 2008, government decree on new GLONASS requirements calls for open CDMA signals with a binary offset carrier or BOC (2,2) signal structure centered at 1575.42 MHz and a BOC (4,4) signal centered at 1176.45 MHz — essentially corresponding to the center points of GPS signals at the L1 and L5 frequencies and nearby Galileo and Compass signals.

An additional GLONASS FDMA signal will be located at L3 frequencies (1197.648–1212.255 MHz), just below the GPS M-code at L2.

Russia will implement the new signals on the next-generation GLONASS-K satellites, with the first launch currently expected in late 2010 with flight testing the following year.

Satellite Launch Will Aid DoD GNSS Users to Anticipate Space Weather Effects

Communication/Navigation Outage Forecasting System (C/NOFS) satellite, General Dynamics

On Wednesday (April 16), a U.S. Air Force team successfully launched the Communication/Navigation Outage Forecasting System (C/NOFS), an experimental satellite designed to monitor the ionosphere and predict conditions that would disturb radio communications, including GNSS signals.

The satellite was ultimately deployed from a Pegasus rocket following an air launch from a Lockheed L-1011 that had taken off from Kwajalein Atoll in the mid-Pacific Ocean. First transmissions from the spacecraft were acquired shortly after it reached orbit.
