ESA Report: Galileo IOV Transmitting on all 3 Frequencies

The European Space Agency (ESA) has reported its first successful reception of triple-frequency signals from a Galileo in-orbit validation (IOV) spacecraft.

The weekend of December 17 all Galileo signals were activated simultaneously for the first time across the European GNSS system’s three spectral bands, known as E1 (1559–1592 MHz), E5 (1164–1215 MHz), and E6 (1.215–1.300 MHz). The accompanying graphic displays the signals spectral profile.

Conference Survey Reflects North American Leadership in GNSS Innovation, Delays in Galileo Program

A survey of 140 attendees at last week’s European Navigation Conference (ENC 2011) in London, England, produced a fascinating assessment of GNSS expectations in the coming years — and how that assessment has changed since 2007.

Sponsored by Helios, a UK business and technology consultancy working in the transportation and technology domains, the survey asked delegates eight questions with multiple choice answers, and recorded their responses using handheld keypads and live electronic voting.
