US legislates on eLoran

The US House of Representatives has directed the Secretary of Transportation to establish an eLoran system.

On 19 May a bill was introduced into the House that required the Secretary of Transportation to work through the Coast Guard to establish an eLoran system. This follows recent discussion of the topic at 2 Senate hearings, a House hearing that was devoted almost exclusively to GPS vulnerability and a bill passed by the House in 2016.

President of the Resilient Navigation & Timing Foundation (RNTF), Dana Goward, explains that Congress has been interested in this topic since 2004, when President Bush declared GPS essential to national and economic security and directed a backup capability be acquired. If the interest is more obvious now, it is probably because threats to GPS satellites and signals are increasing. The Director of National Intelligence reported this month that Russia, China, Iran and North Korea are focusing on improving their already impressive ability to jam GPS - and the Department of Homeland Security (DHS) reported in January that threats to harm the US via GPS disruption were increasing.

But, despite the topic being raised in 2004, nothing material has happened in the US the meantime - the long and tortuous history is related by Dana at the link below.

When asked whether the the bill will now pass the Senate and become law, he responds 'I am sure Senators are as concerned as members in the House about protecting GPS and America. Everyone we have spoken with on Capitol Hill, once they understand the vulnerabilities and threats, has supported getting to a solution as quickly as possible.'
