The GPS program sustained a cut of more than six percent from the levels in the president’s proposed budget for Fiscal Year 2014 (FY14), increasing the likelihood that the Next Generation Operational Control System (OCX) will be delayed and putting pressure on budgets in future years to make up for cuts to modernization efforts.

ESA Director General Jean-Jacques Dordain during his annual press briefing. ESA photo by S. CorvajaSpeaking at his annual press conference in Paris last Friday (January 17, 2014), European Space Agency (ESA) Director General Jean-Jacques Dordain was cool, collected and, importantly, positive, as he laid out plans and parried questions on a whole range of ESA issues. From the Rosetta mission to manned space flights, Swarm, Gaia, Sentinel and Copernicus, and of course Galileo, he set the stage for an ambitious 2014.

Applanix Corporation announced that today (November 12, 2013) that the Trimble CenterPoint RTX correction service will be available across its entire airborne mapping portfolio.
Trimble CenterPoint RTX correction service is a GPS-, GLONASS-, and QZSS-enabled correction service built on Trimble RTX technology that provides high-accuracy GNSS positioning without the use of traditional reference station-based differential RTK infrastructure.

U.S. aviation officials on Monday (December 30, 2013) named the winners of a high-stakes contest to operate one of six new research and test sites for unmanned aircraft. The Federal Aviation Administration (FAA) will now work to help the sites set up safe operations and create the structures needed within the agency to help it use the sites’ research results.

John PorcariThe U.S. Department of Transportation (DoT) is asking the Air Force to cancel its plan to add navigation data to two key civil GPS signals this year, saying they are concerned that the approach and “nonstandard engineering tools” military officials plan to use could put GPS users at risk.

Tim Springer, PosiTim UGA common refrain in the world of GNSS is the desire for “interoperability,” the use of signals from multiple systems without a decline — and potentially even an improvement — in the quality of results.
Achieving this depends on large part in establishing comparable parameters — particularly the geodetic references and timing systems — among the GNSSs along with a dense network of ground reference stations that can provide continuous, precise monitoring of satellites’ orbital positions.

Approval by the European Parliament of the new 2014-2020 European Union (EU) budget last November was widely seen as a step in the right direction for the 28-nation union, after more than a year of sometimes bitter monetary wrangling.
The Parliament quickly followed the move by voting to approve the financing and governance of Europe’s satellite navigation program over the same period. The measure passed the Parliamentary ballot by an impressive margin, with 603 votes in favor, 29 against, and 59 abstentions.

The eDLoran receiver including antenna is mounted in a standard enclosure (14x14x10cm) for GPS-RTK equipment provided by AD Navigation (Norway)The Dutch Pilots Corporation and Reelektronika announced today (January 7, 2014) the successful development and test of an Enhanced Differential Loran (eDLoran) backup to GNSS in The Netherlands.
Trials at sea and in the Rotterdam Europort harbor area met the requirement for absolute accuracies in the five-meter range, according to Durk van Willigen, CEO of Reelektronika, and Wim van Buuren, Loodswezen’s information & communications technology (ICT) and innovation manager and board member.

Federal efforts to protect positioning, navigation and timing (PNT) signals came under sharp criticism during the December meeting of the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board, with the Department of Homeland Security (DHS) getting a bureaucratic ear boxing for having done little so far to specifically protect GPS.

Lawmakers are poised to sharply limit the ability of foreign nations to own or control satellite system monitoring stations on U.S. territory, a rare show of congressional cooperation triggered by a Russian request to place stations supporting its satellite navigation system on American soil.
