Two important US Government announcements have been published on Dana Goward’s Resilient Navigation & Timing Foundation blog in recent days:

1.    The US President has signed Law requiring the Secretaries of Defense, Transportation and Homeland Security to complete a demonstration of a GPS backup capability in the next 18 months.

2.    Senators Ted Cruz and Ed Markey have introduced the National Timing Resilience and Security Act of which directs the Secretary of Transportation to work in consultation with the Secretary of Homeland Security and Commandant of the Coast Guard, to provide for the establishment, sustainment, and operation of a land-based, resilient, and reliable alternative timing system to Global Positioning System (GPS) satellites.

In addition, the UK has been active in assessing the dependency on satellite based timing and position and a Blackett review is just about to be published by the Government Office for Science.  It will be an important read for owners and operators of critical infrastructure which rely on the Global Navigation Satellite System for time and position.  It is anticipated that the Blackett review will be available early in 2018.
