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.

Military GPS Budget Appears Steady as President Bids to Slow Defense Cuts

Spending pressures on the Pentagon seem to be coming from every direction, and the GPS program appears unlikely to avoid them entirely.

The growing needs of veterans are poised to force up health care budgets and higher transportation costs and operating tempos have dug a $22 billion-hole in the accounts for Overseas Contingency Operations in places such as Afghanistan.
