Interview: ESA’s Galileo Director Paul Verhoef

Last February, Paul Verhoef took up the directorship of ESA’s Galileo Program and Navigation-related Activities, and he hasn’t had time to look back since. The successful launch on May 25 2016 of two more satellites is just one of many milestones stretching ahead of him.

Successful Launch Continues Build-Out of Galileo Constellation

The European GNSS program added two more spacecraft to its constellation this morning (May 24, 2016) with the launch of Galileo satellites 13 and 14. They lifted off together at 08:48 GMT (10:48 CEST, 05:48 local time) atop a Soyuz rocket from French Guiana.

This seventh Galileo launch went by the book: the first three Soyuz stages placed the satellites safely into low orbit, after which their Fregat upper stage hauled them the rest of the way into their target medium-altitude orbit in plane A, slots 2 and 6.

The "Brussels View" from Prague

Last October, the European GNSS Agency (GSA) Administrative Board reelected Carlo des Dorides as executive director of the GSA, giving him a second — and final — four-year term in charge of this key agency responsible for supporting the effective operation, maintenance, and security of Europe’s satellite navigation systems. We met with him recently at the GSA office in Prague to learn how he plans to see out his mandate.

Inter-Signal Correction Sensitivity Analysis

Modernized GPS satellites give civil users the ability to achieve dual L1/L2 PY accuracy using dual L1CA/L2C ionosphere-free measurements and, with IIF satellites, dual L1/L5 signals. Because broadcast GPS ephemeris data is based on an ionosphere-free pseudorange calculated from dual L1PY/L2PY measurements and the civil signals are not all perfectly aligned to it, new broadcast parameters and a new modernized dual-frequency algorithm are needed in order to align new signals with the dual L1/L2 PY signal.

Boubeker Belabbas: At Home in the World

Boubeker Belabbas' Compass Points

Boubeker Belabbas, an expert in aerospace mechanics and safety-critical GNSS applications, grew up in Bordeaux, a city of wine, and works in Munich, a city of beer. But he started out in the land of mint tea: a small village in the north of Algeria in the region called Kabylia.
