Filling the PNT Holes – Why Non Satellite-Based Technology is Urgently Needed

Monday, 25 February 2013

“Despite its impressive legacy of successfully driving many essential position, navigation and time (PNT) capabilities, GPS is not an infallible system and requires improvement to meet new threats, needs and PNT challenges…  Unfortunately, despite a number of improvements that can be made, GPS will always suffer from System limitations, many of which are inherent in all Global Navigation Satellite Systems.

A very new back-up technology which is not yet well known to the public is Locata – a terrestrial positioning system that remains accurate in the absence of GPS, is vastly more accurate and operationally more robust than eLoran, and which can be flexibly modified to meet specific application requirements.”

This seminal article, which is the feature story in the February 2013 issue of The American Surveyor  magazine, the most high-profile magazine in North America for professional surveyors, highlights the growing worldwide concern with the obvious vulnerabilities and insufficiencies of GNSS-based positioning.
