Global Navigation Satellite Systems Engineering, Policy, and Design
China’s BeiDou will accelerate the pace of its development, even as the world’s other three GNSS systems are experiencing delays and difficulties, according to speakers in the opening session of the China Satellite Navigation Conference (CSNC 2014) today (May 21) in Nanjing.

The ninth meeting of the International Committee on GNSS (ICG) will take place in Prague, Czech Republic, from November 10 through November 14 2014.
This meeting is hosted by the European Union and will be organized by the European Commission and the European GNSS Agency (GSA).

UK emergency call dispatcherEuropeans agree — assisted GNSS or A-GNSS provides the best means for locating emergency callers using mobile phones. Although the question of who should pay is remains to be answered, new regulations aimed at enabling the service now seem inevitable.

Widespread reports of intermittent GPS receiver outages may well end this week as the U.S. Air Force wraps up an “extended navigation mode” functional checkout of a GPS satellite, designated Space Vehicle Number (SVN) 64, a Block IIF spacecraft launched in February.
The problem affects only user equipment that erroneously uses navigation message data from the satellites, which had yet to be set "healthy."

Well, I could have taken up the subject of the deteriorating condition of U.S./Soviet, excuse me, U.S./Russian relations. But there are only so many windmills that I have time to tilt at.
So, rather than tracing the dissolution of bilateral GNSS cooperation in the wake of Russia’s reclaiming the Crimea and, who knows, perhaps eventually a large swath of eastern Ukraine, I thought I’d turn to an only slightly more remediable issue — GNSS carriage requirements.

Doug Taggart, Overlook Systems Technologies In the “gee-whiz” awesomeness of proliferating GNSS apps, it’s sometimes hard to remember that Global Positioning System originated as a military system designed to meet strategic and tactical needs on the battlefield.
And, with the U.S. Air Force continuing its 40-year mission as the executive agent for sustaining GPS, that undiminished military role plays no small part in ensuring the availability and reliability of the U.S. contribution to the GNSS system of systems.

Jim Williams, FAA UAS Integration Office. AUVSI photoCompanies 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.

Rep. Frank LoBiondo, New JerseyNo federal funding is available nor will there be for the six test ranges chosen to help integrate unmanned aircraft into the national airspace, a key lawmaker told attendees at a prominent conference on unmanned systems.
“I don’t see Congress doing that [providing money for the ranges],” said Frank LoBiondo, R–New Jersey, the chairman of the House Aviation Subcommittee in response to a question during an Association for Unmanned Vehicle Systems International (AUVSI 2014) conference in Orlando, Florida, last week.

On Friday (May 16, 2014) the U. S. Air Force successfully launched the sixth Global Positioning System (GPS) IIF satellite on board a United Launch Alliance Delta IV launch vehicle. The launch took place at 8:03 EDT from Cape Canaveral Air Force Station, Florida.
The GPS IIF generation of satellites, built by The Boeing Corporation, provides greater navigational accuracy through improvements in atomic clock technology, a more resilient signal for commercial aviation and safety-of-life applications and a longer design life of 12 years.
