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

Next Galileo Satellite Reaches French Guiana Launch Site

August 9, 2012By

The next Galileo navigation satellite has touched down at Europe’s Spaceport in French Guiana, to begin preparations for its launch in October, reports the European Space Agency. Cocooned within a protective, air-conditioned container, the satellite left the Thales Alenia Space Italy plant in Rome on Monday evening for nearby Fiumicino Airport. read more

Second Galileo IOV Satellite Transmitting Signals

January 16, 2012By

On Monday, 16 January, at about 02:18 UTC, the second of the two Galileo In-Orbit Validation (IOV) satellites, FM2 (Flight Model 2) also known as GSAT0102, started transmitting navigation signals on the L1/E1 frequency using the E12 ranging code, according to tracking reports from the COoperative Network for GIOVE Observation (CONGO). read more

First Galileo IOV Satellite Producing Full Spectrum of Signals

January 3, 2012By

Europe’s first Galileo satellite appears to be functioning as expected, transmitting test signals received by the European Space Agency’s ground station in Redu, Belgium, across the whole of its assigned radio spectrum, ESA reports. The first two Galileo satellites were launched by Soyuz from Europe’s Spaceport in French Guiana on October 21. They are currently in the midst of a rigorous campaign to check that their highly sophisticated navigation payloads are operating as planned, unaffected by the strains of launch. read more
