Federal Railroad Administration Announces Status Updates to GPS-Aided Collision Avoidance System

The Federal Railroad Administration (FRA) last week released a status update that calls for railroads to roll out Positive Train Control (PTC) technologies, which incorporates GNSS technology, as soon as possible. The update also underscores the Obama administration’s calls to provide more funding to assist commuter railroads in implementing PTC.

PTC uses GNSS, but mostly GPS, to prevent train-to-train collisions, high-speed derailments, and the unauthorized movement of trains into work zones.

GPS OCX to Halt Work September 15 unless Lawmakers Act

A lack of funds will force a shutdown in the development of the GPS new ground system on September 15 unless lawmakers act on a July request to redirect funds, according to the Air Force.

Although the doors likely would only be closed for a little over two weeks, a hiatus would add substantially to the total cost of the GPS Next Generation Operational Control System (OCX) and further delay completion of the already behind-schedule program, the Pentagon has told lawmakers.

Ligado Lobbying Expenses Jump as Election Looms, Near-GPS Spectrum Sought

With control of Congress increasingly up in the air and a new administration due to take the reins in six months, organizations around Washington, are working hard to get friendly provisions in place before sympathetic officials have to change jobs.

Public records show that would-be broadband provider Ligado Networks, which hopes to rezone frequencies neighboring those used by GPS despite a proven interference risk, is on track to double its lobbying expenditures this year.

GNSS Forum: Seven Easy Ways the Administration or Congress Could Get a Quick Win Protecting GPS and America

The U.S. Secretary of Defense has said “I hate GPS” and “I want to unplug the military from GPS.” Senior officials at the Department of Homeland Security (DHS) have called GPS “a single point of failure for critical infrastructure.”

GPS signals are used by virtually every technology. Their disruption for more than a brief period of time or over more than a small area could impact cell phone service, financial systems, computer networks, emergency radio systems, and every mode of transportation. It could be catastrophic for America.
