CPNT Go Time for USDOT: An Exclusive Interview with the PNT Director

Just five months ago, the U.S. Department of Transportation, Office of the Assistant Secretary for Research (DOT/OST-R), Volpe Center issued a 15-day quick-turn Request for Information (RFI), which was subsequently extended for an additional 15 days, to industry seeking feedback on the availability of operationally ready (Technical Readiness Level or TRL ≥ 8) complementary positioning navigation and timing (CPNT) technologies to meet critical infrastructure needs when GPS service is not available, degraded or disrupted.

AUSA Highlights Need for Systems with Resilient Navigation

The Association of the United States Army’s (AUSA) annual conference highlighted the growing popularity of small unmanned aircraft as well as the need to develop and refine counter-UAS systems to go up against them—all of which must operate in GPS-denied or degraded environments. Many, if not all, of the systems featured rely on precise positioning, especially in the GPS-denied environments frequently encountered on the modern battlefield.

PNT Makes the World Go Around: The UK’s New Alternative PNT Strategy

There has never been a clearer and more widespread acknowledgement of PNT vulnerability. With its new strategy for ensuring the continuity of positioning, navigation and timing (PNT) services, the United Kingdom adds considerable impetus to a trend that has already witnessed new determination on the parts of the United States and the European Union to assess real, alternative PNT (A-PNT) and/or complimentary PNT (CPNT) solutions.
