Official: Foreign GNSS Signals Need FCC Authorization for Use in United States

Ronald Repasi, deputy chief of the FCC’s Office of Engineering and Technology, speaking at a 2012 hearing of House Energy & Commerce Subcommittee on Communications and Technology

A rule largely aimed at opening trade in telecommunication services will require Russia and other international providers of GNSS services to apply for authorization before their navigation signals can be legally used in the United States, a Federal Communications Commission (FCC) official has told GPS experts on the Space-based Positioning, Navigation, and Timing (PNT) Advisory Board.

Canada Eases Rules for Commercial Unmanned Flights; UAV Mischief Mounts in U.S.

Transport Canada rules on UAV operation

Canada has lifted a key filing requirement on professional drone operators, allowing firms flying small, unmanned aerial vehicles (UAVs) to conduct for-profit flights without prior approval as long as they follow a lengthy set of rules and obtain insurance.

Galileo Satellite Recovered, Transmitting Navigation Messages

Europe’s fifth Galileo satellite, one of two delivered into a wrong orbit by a Russian Soyuz-Fregat launcher in August, transmitted its first navigation signal in space on Saturday (November 29, 2014) after reaching its new target orbit.

According to the European Space Agency (ESA), a detailed test campaign is under way now the satellite has reached a more suitable orbit for navigation purposes.

2nd GLONASS-K1 Finally Reaches Space

GLONASS-K1 at ISS-Reshetnev

Russia launched the second and final GLONASS-K1 flight-test satellite on Sunday (November 30, 2014) from the Plesetsk cosmodrome on board a Soyuz 2-1B rocket.

Built by ISS-Reshetnev, the satellite broadcasts five navigation signals in three frequency bands – L1, L2 and L3. A civil CDMA signal is among those to be transmitted in the L3 band. The spacecraft also carries new equipment to support the international search and rescue system COSPAS-SARSAT: a payload that can relay signals from users in distress.

Funding at Risk as Work on UAV Standards Falls Behind

Efforts to set aviation standards for larger unmanned aerial vehicles (UAVs) have fallen behind schedule, threatening essential funding for related tests and possibly complicating an Air Force program that needs the standards to make technology choices.

The schedule is slipping because initial estimates of the work involved in setting the standards for detect-and-avoid (DAA) technology did not fully capture the complexity and extent of the effort necessary. DAA technology is intended to

Witnesses: FAA Funding Problems at the Heart of NextGen Problems

Lawmakers meeting to examine reauthorization of the Federal Aviation Administration (FAA) and the agency’s work on the GNSS- and satellite-based, next-generation air traffic system (NextGen) weathered a scathing critique of their own efforts — particularly their work on the federal budget.

Year 10

Every so often, anthropologists — and maybe a few mathematicians — have a field day puzzling over the origins of our positional base-10 numeral system.

Oh, not the historical origins themselves, the Hindu-Arabic innovations beginning in the 5th and 6th centuries. That’s all pretty much agreed.

No, I’m referring to the possible physiological inspirations, the readily visible digits at the ends of our limbs: 10 fingers, 10 toes.

Coincidence? Does nature have coincidents, or does it abhor them like vacuums — o horror vacui?
