FAA UAV Exemption Process Is in Place, Though Perhaps Imperfect

FAA UAV Exemption Process Is in Place, Though Perhaps Imperfect

Companies hungry to offer commercial services in the United States with unmanned aircraft finally have something to chew on.

The Federal Aviation Administration (FAA) has laid out a process whereby a carefully selected set of unmanned aerial systems (UAS) may be granted an exemption to do for-pay flights before the first broad rules for U.S. flying unmanned aircraft are finalized.

Michel Monnerat: Out of Africa — GNSS

Michel Monnerat: Out of Africa — GNSS

SIDEBAR: Michel Monnerat’s Compass Points

“I was born in Arles, in the south of France,” says Michel Monnerat, “but I left France before my first birthday. We moved many times, from place to place.”

Monnerat’s father worked for a civil engineering company, specializing in maritime works — harbor construction, coastal protection, and such. His family lived in Ivory Coast, Cameroon, and Tunisia, but Monnerat spent most of my early life in Lomé, the capital city of Togo.

It’s Spring, and EGNOS Is in the Air

It’s Spring, and EGNOS Is in the Air

Europe has been talking up its European Geostationary Navigation Overlay Service (EGNOS, for short) — and why shouldn’t it? Talking about Galileo doesn’t get satellites off the ground. EGNOS, on the other hand, is up and running, and has been since 2009. If the object is to build confidence in European savoir faire, why not talk about a real success like EGNOS?

European Officials Consider Galileo Mandate for Mobile Devices

European Officials Consider Galileo Mandate for Mobile Devices

Perhaps taking a page of Russia’s playbook for mandating use of GLONASS in certain equipment, European officials are looking into the possibility of requiring the addition of Galileo capability to mobile phones and other device and platforms.

As it has become clear that the European GNSS will be the third or fourth GNSS available — after GPS, GLONASS, and probably BeiDou — the European Union’s executive body, the European Commission, is exploring non-market strategies to increase adoption of Galileo by manufacturers and users.

At ENC 2014: A GNSS Wake Up Call for Europe

At ENC 2014: A GNSS Wake Up Call for Europe

Brad Parkinson

Among the key topics to come out of this year’s European Navigation Conference (ENC 2014) in Rotterdam is how safe — or unsafe — we really are, and who in Europe cares. The answer is, a lot of people care, but almost no one can do anything about it.

Professor David Last, strategic advisor at the General Lighthouse Authorities of the UK & Ireland, made the case before the conference had even started, at the pre-conference “Resilient PNT Forum.”

QZSS’s Day in the Sun at Munich SatNav Summit

The Russians may have taken a rain check, but Asian representatives were out in force at this year’s Munich Satellite Navigation Summit, held last week (March 25–27, 2014). The general message from China, Japan, and India was that they are moving forward quickly with their own GNSS systems, while seeking active cooperation, both technical and commercial, with international partners.

Just when they thought it was safe to go back into space . . . .

The Russian GLONASS system, which had appeared to be recovering from a series of organizational and technical problems in recent years, appears to have suffered a systemic disruption during the past 24 hours — beginning just past 1 a.m. Moscow time on April 2 (UTC+4) — 6 p.m. EDT on Tuesday (April 1, 2014).

U.S. Air Force Authorizes Lockheed to Finish GPS III SVs 7 & 8

U.S. Air Force Authorizes Lockheed to Finish GPS III SVs 7 & 8

The U.S. Air Force has awarded Lockheed Martin more than $245 million in contract options to complete production of its seventh and eighth GPS Block III satellites.

The two space vehicles (SVs 07–08) received initial funding under a February 2013 long-lead material contract for the Air Force’s second set of four satellites, GPS III SV 05–08. Similar to this current award announced yesterday (April 1, 2014), the Air Force exercised an option to complete production of SVs 05–06 in December 2013.
