Equation 1GNSS modernization includes not only the global coverage capabilities of GPS, GLONASS, Galileo, and BeiDou, but also regional GNSS enhancement systems such as Japan’s Quasi-Zenith Satellite System (QZSS), the Indian Regional Navigation Satellite System (IRNSS), and the European Geostationary Navigation Overlay Service (EGNOS).

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.

The nation’s leading GPS experts are struggling to quantify how the world’s premier navigation and timing system affects the U.S. economy, an effort critical to building a political firewall around GPS spectrum in the face of ballooning demand for broadband capacity.

Brad Parkinson, the first director of the NAVSTAR GPS Joint Program Office, once said that his work with the Global Positioning System had led him to validate an interpretation of “prime law” suggested by a colleague: one thing leads to another
Forty years ago today, that principle culminated in a key decision by the Department of Defense to proceed with what became the GPS program.

Crowdsourcing has gained some attention in the GNSS community as a means for detecting and mitigating RF interference and signal spoofing.
In the past year, researchers and commercial ventures have developed ways to take advantage of the GNSS-derived knowledge of real-time location of participants to create ad hoc networks of couriers.

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.
