The Low Cost of Protecting America

GPS World, January, 2014, by Dana A. Goward

eLORAN Recommended. The IDA study team, which included Brad Parkinson, widely recognized as the father of GPS, unanimously recommended that an existing and outdated nation-wide navigation system called Loran-C be greatly updated and modernized to eLORAN. Such a system would provide a navigation and timing signal comparable with and complementary to GPS.

“eLORAN is the only cost-effective backup for national needs; it is completely interoperable with and independent of GPS, with different propagation and failure mechanisms, plus significantly superior robustness to radio frequency interference and jamming. It is a seamless backup, and its use will deter threats to US national and economic security by disrupting (jamming) GPS reception.”
