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.

China will begin launching BeiDou-2 satellites again in 2013 as it begins its test program for the third generation of the nation’s GNSS program.

After launching 16 satellites since 2007 (including six last year) to establish the current regional constellation with 14 operational satellites and publishing an official interface control document December 27, China called a halt to further launches to evaluate the performance of the system and complete a development plan for the system.

GPS jamming attacks from North Korea that have increased in frequency and duration since they began August 2010 have prompted the South Korean government to implement an enhanced Loran (eLoran) systems that will cover the entire country by 2016.

The South Korean government completed design, development, and construction documents for the eLoran system in February and will procure the system infrastructure through international competitive bidding.
