In 1589, at the age of 25, Galileo Galilei toiled up the 294 steps of a 55-meter bell tower in Pisa, Italy, where he was tutoring math students at the time.

According to his pupil and later biographer, Vincenzo Viviani, Galileo carried with him two cannonballs, one twice the weight of the other. When he reached the top of the tower, he went to the lower balcony of the tilted structure and dropped the two balls simultaneously.

The Year’s Top Stories from Inside GNSS

If the readership of insidegnss.com news is any indication, 2011 was the year of LightSquared.

Articles about the would-be wireless broadband company that wants FCC approval to set up a terrestrial network transmitting on frequencies next door to GPS and other GNSS L1 signals garnered the most page views on our website for 6 out of 12 months.

LightSquared Petitions FCC to Confirm Company’s Rights to GPS Spectrum

LightSquared today (December 21, 2011) asked the Federal Communications Commission (FCC) to confirm the company’s right to use spectrum licensed to it and that commercial GPS manufacturers have no right to interference protection from LightSquared’s proposed wireless broadband network.

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.

LightSquared Postpones International Expansion Effort

A GPS app on a Japanese smartphone. The GPS Council there told the FCC that any signal degradation could jeopardize the Global Positioning System’s standing as a global standard.

LightSquared has dropped, for now, efforts to expand its wireless broadband plans to markets in other countries, Inside GNSS has learned.

The Virginia firm was working this summer on proposals to the International Telecommunication Union, including one aimed at addressing compatibility issues between ground stations or “complementary ground components” of mobile satellite services and other frequency-using services.
