A method of decoding an unknown pseudorandom noise code uses a conventional GNSS antenna and receiver with modified firmware. The method was verified using the signals from the Galileo In-Orbit Validation satellites. read more

Transmissions from Galileo Satellite IOV-4 Begin

December 13, 2012By

News courtesy of CANSPACE listserv. The Technische Universitaet Muenchen has reported that transmissions of the L1/E1 signal from Galileo satellite IOV-4 (FM-4) started at about 17:15:10 GPS Time December 12. The navigation signals of both of the recently launched in-orbit validation satellites have now been activated. A number of stations in the Cooperative Network for GNSS Observation as well as... read more

The System: Patent Attempt on GPS, Galileo Signals Appears Done

December 1, 2012By

One of the GNSS controversies of the past year ended, not with a bang nor with a whimper, but like the fog, silently creeping away on its little cat feet. The UK patent applications against the interoperative GPS/Galileo signal design appear to have been dropped. Vague rumblings emerged throughout spring and summer this year that two British technologists, backed by... read more

By Richard B. Langley, Simon Banville, and Peter Steigenberger. For a brief period, and for a few hours on certain days, signals from the first four orbiting Galileo satellites could be received by state-of-the-art multi-frequency, multi-constellation GNSS receivers. Although not intended for actual positioning tests, the satellites did provide a first opportunity to assess the prototype Galileo signals in the... read more

The System: Galileo IOV Satellites Now in Orbit

November 1, 2011By

The first two satellites for Europe’s Galileo global navigation satellite system were lofted into orbit October 21 by the first Russian Soyuz vehicle ever launched from Europe’s Spaceport in French Guiana in a milestone mission, reports the European Space Agency (ESA). The launch occurred one day after initially scheduled to resolve a problem with the ground-support fueling system. The Soyuz... read more

GIOVE-B E1 CBOC Signal Quality Assessment
GIOVE-B has been in orbit for just over one year. How well is it performing? In particular, what can we say about one of GIOVE-B's pioneering features: its E1 CBOC signal? In this month's column, we take a detailed look at a particular monitoring and assessment program set up to examine the GIOVE-B signals and discuss some of its initial CBOC results. The successful operation of this program bodes well for its use in future validation campaigns. read more
