HIGH HORIZONTAL DILUTION OF PRECISION (HDOP) ADVISORY FOR 29 JULY 2016

Users of the Global Positioning System (GPS) in an area extending to the Northeast from Fort Collinson and Ulukhaktok to the Northeaster tip of Victoria Island in The Beaufort Sea, and in an area of the Antarctic Coast to the Southeast of the South Georgia and South Sandwich Islands may experience short periods of high HDOP/PDOP (HDOP >6) at various times between 291123Z and 291131Z July 2016 due to satellite maintenance (please refer to NANU 2016047, available on our Constellation Status Page).

PNT is the quiet backbone of everything but too many leaders still don't see the risk.

But you do. You understand the systems, the dependencies, the failure chains. That insight is rare — and it's exactly what your country needs right now. Contact your government leaders and industry decision-makers and tell them resilient PNT isn't a feature — it's the foundation everything else depends on.
