SIDEBAR: Di Qiu’s Compass Points

Landing all-weather aircraft safely in storms. Protecting sensitive data not only through encryption but based on the location at which it is being accessed. Ensuring that accurate and timely information reaches first responders responding to emergencies. 

Although still in the early part of her career, Di Qiu has already made significant contributions to these crucial applications of navigation technology.

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.”

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.

Paul Flament is head of the European Commission’s Satellite Navigation Unit. His primary job, essentially, is to manage the Galileo program of the European Union (EU). With four operational satellites now in orbit and an ambitious schedule to set in place a constellation of 26 by 2015, Flament sat down with Inside GNSS to talk about a number of pressing issues that could affect the future of Galileo.

Flament first addressed the EU GNSS Regulation, the much-anticipated document that sets out just who will do what in the future Galileo program.

The Air Force will decide this fall whether to build more GPS III satellites or move to a new generation of spacecraft, the leader of Air Force Space Command told Congress last week.

“We’re on contract right now . . . through (GPS III) satellite vehicle number eight. Satellite vehicles nine and beyond – the acquisition strategy for that – will be debated in the fall,” General William Shelton, commander of Air Force Space Command (AFSPC), told the House Armed Services Committee on April 25.
