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. read more

Not quite. Not nearly. Not by the farthest, if measuring into... read more
