eLoran trials in US
US companies Exelis and UrsaNav have entered an agreement with DHS and the USCG to trial eLoran for PNT back-up.
The companies, together with the Department of Homeland Security’s Science and Technology Directorate (DHS S&T) and the US Coast Guard, have entered into a cooperative research and development agreement (CRADA) for testing and demonstration at former Loran-C sites.
The sites represent the legacy infrastructure of the decommissioned Loran-C system that could be retained and upgraded to provide an eLoran service on the same 100 kHz frequency.
The team explains that they will evaluate eLoran as a potential complementary system to GPS within the US. The capabilities and potential utilisation methods of eLoran will be explored in depth to identify all strengths and capacities as well as potential vulnerabilities of the technology.
Under the CRADA, the companies will use the former Loran-C assets to put eLoran signals in space for research, test and demonstration of the ability of eLoran to meet precise positioning, navigation and timing (PNT) requirements of government and private critical infrastructure.
The first station planned to carry eLoran is located in Wildwood, NJ, giving a claimed range of up to 1,000 miles.
An Exelis VP comments:
'eLoran is an ideal technology to complement GPS for critical, resilient and assured PNT. eLoran is a difficult-to-disrupt technology that offers PNT and wide area broadcast data capabilities indoors, in underground locations and other GPS-denied environments.
UrsaNav's President adds:
'A preponderance of government, academic and industry reports have concluded that eLoran is the best independent, multi-modal solution to provide assured PNT as a complement to GPS.'
