| Strengthening International Cooperation on Long-Range Navigation to Overcome GPS Jamming |
| - Discussions on policy and technology cooperation in terrestrial navigation with the UK and France in Seoul beginning November 11 |
The Ministry of Oceans and Fisheries (MOF; Minister Chun Jae-soo) announced that it would be holding a meeting of the standardization working group for the terrestrial navigation service (eLoran)* with the UK and France in Hotel Koreana, Seoul from Tuesday, November 11 to Wednesday, November 12. The eLoran system can provide stable location, navigation, and time information even in GPS radio jamming situations.
* enhanced Long-range navigation: A terrestrial navigation system that calculates location by measuring the arrival time of radio waves (100 kHz) transmitted from three or more ground-based transmitters
eLoran has attracted attention as a navigation system that complements GPS since it is not affected by satellite signal interference and it uses a high-power, low-frequency signal and provides high location accuracy within 20 meters, plus it can provide precise timing information up to 1/1,000,000 of a second (10-7 seconds).
This first-ever meeting will be attended by 30 experts from various countries, including representatives from three countries: Republic of Korea, United Kingdom, and France. They will share the latest policy and technology development trends in the eLoran field and discuss key agenda items, including: ▲ Strategic plans to standardize eLoran, and ▲ Measures to establish a consultative body for international eLoran cooperation and regular meetings.
MOF plans to introduce ROK's eLoran system—built primarily in the West Sea—to counter GPS signal interference and to demonstrate the service directly at Incheon Port, which is expected to garner great interest from participating countries.
Through this meeting, the Ministry plans to strengthen cooperation in the field of alternative navigation system technology and—based on this—enhance the capability of ROK's satellite navigation system to withstand GPS signal jamming and improve maritime safety.
“We expect this first meeting to be an important starting point for international cooperation in the field of eLoran. We will do our best to lead the way in international standards for eLoran and expand cooperation with major countries to establish a navigation system that will prepare against GPS signal jamming,” said Choi Seong-yong, Director General of MOF’s Maritime Safety Bureau.
Dr Mark Brammer, UK Positioning Programme Lead from the National PNT Office concurred with the Director General and noted that “the experience and expertise of the Republic of Korea, United Kingdom and France in developing and operating eLoran and other navigation technologies is the ideal starting point for adoption and interoperability standards across the globe”.
