eLoran Progresses Toward GPS Back-Up Role in U.S., Europe

June 25, 2015

As of June 19, eLoran is on the air in the United States. The low-frequency signal emanates from a former U.S. Coast Guard Loran Unit in Wildwood, N.J., which sports a 625-foot signal mast that has been out of action for five years. The signal is receivable at distances of up to 1,000 miles. The eLoran navigation and communications signal is difficult to disrupt; further, it could be an important part of enabling UAVs to fly safely in our airspace.

eDLoran: The Next-Gen Loran

June 28, 2014

Potential GNSS Back-up Improves to GPS-Level Accuracy
A new enhanced differential Loran system demonstrates 5-meter accuracy not achievable by the current DLoran system, and requires less expensive reference stations. A prototype tested in Rotterdam’s Europort area uses standard mobile telecom networks and the Internet to reduce correction data latency — a key source of error — by one to two orders of magnitude.

eDLoran Surprise: European Navigation Conference 2014

May 14, 2014

At the ENC-GNSS Conference in Rotterdam, we delved into actions necessary to officially use EGNOS (giving me déjà vu from WAAS’s early days), heard sage words from Brad Parkinson, the father of GPS, and, on the last day, saw amazing proof of a claim many of us initially thought was outrageous —that differential (DLoran) with modern monitoring can result in consistent horizontal accuracies approaching five meters on a moving platform.
