Cooperative Research And Development Agreement (CRADA) Efforts

UrsaNav entered into a Cooperative Research And Development Agreement (CRADA) with the US Department of Homeland Security (DHS), the US Coast Guard (USCG), and Harris Corporation to research, evaluate, and document eLoran technology as a candidate for providing position, navigation, and timing (PNT) information. eLoran will be evaluated as a potential complementary system to the current Global Positioning System (GPS) currently in wide use throughout the world. The capabilities and potential utilization methods of eLoran will be explored in depth, to identify all strengths, capacities, and potential vulnerabilities of the technology.

UrsaNav believes that there is a potentially viable market, in both the public and private domain, for an alternative PNT service that is independent of GPS signal reception or which can be used in GPS-denied environments. The overall goal of the Cooperative Research And Development Agreement (CRADA) is to demonstrate eLoran’ s ability to meet PNT needs in regards to providing redundancy and resiliency to critical infrastructure, by testing positioning accuracy, messaging and timing signal capabilities using either Loran legacy facilities updated to eLoran standards, or new eLoran facilities in the United States. The agreement also encourages exercises of eLoran timing, emergency messaging services, and position capabilities in regional emergency response scenarios using Cooperative Research And Development Agreement (CRADA) resources.

eLoran Transmitter On Air Test Periods

Wi-Fi - 3D
Here you will find the latest eLoran transmitter activity.

The Loran sites at Havre, MT; George, WA, and Fallon, NV will be continuously broadcasting from 0900 (MST) 20 June 2017 through 1200 (MST) on 30 June 2017.

The sites will be operating on the 5990 rate but occasionally may operate at other rates. Only the site at Fallon will be operating as an eLoran site. The sites at Havre and George will be operating as Loran-C sites synchronized to UTC.
