incurred by readers in reliance on such content Published monthly Complements of the Season I n the wake of last months Expert Advice column on eLoran The Low Cost of Protecting America by Dana Goward of the Resilient Navigation and Timing Foundation come several positive comments and encouraging developments Rather than rehearse all the arguments why we should care about this Ill repeat the one word that I heard most often in GNSS circles in 2013 jamming Followed closely by spoofing I have been advocating strongly for reconsideration of the governments domestic Loran decision for the last year or so writes one reader positioned on Washingtons Beltway and specifically working within the Department of Defense DoD to ensure it is aware of international developments for eLoran in the UK and South Korea and the possibilities inherent in other former Loran chains Favorable New Years auguries for positioners navigators and timers The DoD is beginning to recognize the value of eLoran as a complement to GPS not only for international missions but in cooperation with the departments of Transportation and Homeland Security for domestic critical infrastructure Last fall Don Jewells Defense PNT newsletter on the same subject drew this reply from another well known expert One of the key short term actions is to prevent the decommissioned Loran sites from being sold off for subdivisions These sites are a national treasure with unique properties soil conductivity water content metal content and more that are hugely important in siting low frequency positioning systems Those long gone engineers of the 1940s and 50s knew this and chose accordingly Before last months issue appeared but after it had gone to press President Obama signed the National Defense Authorization Act NDAA for 2014 It contained several favorable New Years auguries for positioners navigators and timers The act evinced an acute awareness of the vulnerability of space systems to disruption The act is also a law governing the land Through it Congress requires the administration to among other things explain biennially in its Space Protection Strategy report exactly how in the event space systems are disrupted DoD and the intelligence community plan to provide necessary national security capabilities through alternative space airborne or ground systems Since said administration acted early in its first term to decomission Loran C the congressional directive is pointed The next big thing coming up on the GNSS international horizon takes place in Rotterdam the Netherlands April 15 17 the European Navigation Conference ENC GNSS 2014 It includes a track session on eLoran and other Low Frequency Systems and Ill be there with pencil sharpened Brad Parkinson will give the ENC keynote and he is on record as one of an august group of Institute for Defense Analyses experts who unanimously recommended that the existing Loran C be greatly updated and modernized to eLoran We should hear more from him on this subject amid the wharves waterways and docks of Europes largest port worlds third busiest Theres barely room left to report the successful tests of Enhanced Differential Loran eDLoran by Dutch specialists Reelektronika absolute accuracy of 5 meters in the North Sea and in the Rotterdam Europort harbor area GPS World February 2014 www
