Potential GNSS Back-up Improves to GPS-Level AccuracyA 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.
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.
The North Sea fairly boils with GNSS activity recently. Trials of the eLoran back-up for GNSS, Galileo maritime […]
