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.

Air Force Examining Broader Options for Next GPS III Satellite Buy

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.

North Korea’s GPS Jamming Prompts South Korea to Endorse Nationwide eLoran 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.
