GPS Civil Funding Request Slashed

GPS Civil Funding Request Slashed

Jan Brecht-Clark, director, National Coordination Office for Space-Based Positioning, Navigation, and Timing

With just more than four months to go in the 2013 fiscal year, sequestration and furloughs are taking a bite out of key research and the work of the National Coordination Office (NCO) for Space-Based Positioning, Navigation, and Timing (PNT) — the government nexus for GPS-related policy matters.

The NCO is an interagency organization, explained its director, Jan Brecht-Clark in an emailed response; so, “each individual staff member is subject to furloughs implemented by their home agency as a result of sequestration.”

China Conference Highlights Plans for BeiDou in International Marketplace

China Conference Highlights Plans for BeiDou in International Marketplace

The fourth China Satellite Navigation Conference (CSNC 2013) wound up its three-day run on Friday (May 17, 2013) in Wuhan — by most measures a clear success for an event that has become the nation’s leading GNSS forum.

Well more than 2,000 attendees had their choice of 627 technical papers spread across a broad array of topics in 12 session tracks under the conference theme: BeiDou Application — Opportunities and Challenges.”

ESA Adds System Time Offset to Galileo Navigation Message

ESA Adds System Time Offset to Galileo Navigation Message

The four Galileo in-orbit validation (IOV) satellites now on orbit have begun broadcasting the “offset” between the GPS and Galileo system time, accurate to a few billionths of a second, according to the European Space Agency.

With satellite navigation based around the highly accurate measurement of signal travel times, both Galileo and GPS have their own internal reference time systems used to synchronize all system clocks, including those in the ground segment, on satellites, and in receivers. Galileo System Time is about 50 nanoseconds or less apart from GPS time.

European Commission: Galileo and EGNOS Applications Workshop

European Commission: Galileo and EGNOS Applications Workshop

This European Commission-sponsored workshop  will take place at the EC’s Charlemagne building, Room Alcide de Gasperi (GASP), Rue de la Loi 170 in Brussels.

It begins at 9 a.m. and ends at noon.

Participants will discuss their opinions and experiences with the European GNSS downstream applications sector.

The goal is to "maximise and ensure the market uptake of European GNSS applications," according to the organizers.

White House Moves to Harden Infrastructure against GPS Disruption

System engineers across the country may soon be planning, in some cases perhaps for the first time, what they would do if they could not use the GPS service.

The effort is part of an expanded White House initiative to protect the nation’s critical infrastructure. Alhough infrastructure protection programs have been under way for some time, they did not necessarily address GPS vulnerabilities explicitly.

MUSTER

Existing methods for improving the GNSS performance commonly attempt to enhance the signal processing and navigation estimation parts of a single receiver. Such approaches, however, leave unexplored the potential benefits inherent to the integration of data from multiple receivers.
