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.

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.
