EGEP testbed combined GPS/GALILEO

Europe’s two satellite navigation systems could combine in the future for heightened performance, an airborne test has confirmed. A helicopter flight took place above an alpine valley in Germany, the one place on Earth where Galileo services are already routinely available. Results of the flight test, conducted in September 2012, show that adding Galileo signals to the European Geostationary Navigation... read more

The first switch-on of a Galileo search and rescue package shows it to be working well, according to the European Space Agency. Its activation begins a major expansion of the space-based Cospas–Sarsat network, which brings help to air and sea vessels in distress. The second pair of Europe’s Galileo navigation satellites — launched together on October 12 last year —... read more

Galileo IOV Satellites Begin Transmitting Navigation Messages

January 18, 2013By

News courtesy of CANSPACE listserv. Two of the Galileo In-Orbit Validation satellites, E11 and E12, began transmitting navigation messages on their Open Service signals on January 17. Several stations in the Cooperative Network for GNSS Observation and the International GNSS Service’s Multi-GNSS Experiment network received the messages. The epheremis data in the messages appears to be updated every 10 minutes. read more

Galileo and Compass: A Tale of Also-Runnings

December 19, 2012By

Beating up the backstretch neck and neck, tied for third in the GNSS race, Galileo and Compass today offer some signals and some satellites to GNSS users — as long as those users are researchers. Galileo has more going for it in the way of signals, while Compass holds an edge in the number of satellites. Without an interface control... 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
