The integrated R-Mode navigation system was developed by KRISO for improving marine safety
The integrated R-Mode navigation system was developed by KRISO for improving marine safety in Korea▶ Ships are not disturbed during GPS jamming and spoofing.□ A technology allowing for the measurement of ship position without GPS has been developed.□ The Korea Research Institute of Ships & Ocean Engineering (President Keyyong Hong, KRISO) announced on September 1, 2023 that the Institute had developed ‘terrestrial integrated navigation system (R-Mode) technology,’ which allows for the measurement of ship position on the sea even during GPS jamming or failure.□ With global digitalization, position information has been so common that it is often used in our daily life and in the industry. In addition, position information is essential for many means of transportation, including aircraft, ships, and automobiles.□ At present, the general way of acquiring position information is by the Global Navigation Satellite System (GNSS), in which the position is calculated by measuring the travel time of signals transmitted by satellites; the representative example is GPS. However, GNSS is vulnerable to signal failure, jamming, and hacking.□ To overcome the limitation of GNSS, KRISO developed a new terrestrial integrated navigation system (R-Mode) technology. In this technology, different terrestrial navigation signals are transmitted from three transmitting stations on the ground, rather than from satellites, and the distance is measured based on differences between transmitting time and receiving time of each signal.□ KRISO has promoted the ‘terrestrial integrated navigation system (R-Mode) technology’ development program, supported by the Ministry of Maritime Affairs and Fisheries, since 2020. From 2022 to this year, at the Daesan Harbor in Seosan, KRISO has completely demonstrated the key features of the technology, such as broadcasting of actual signals; receiving and processing of navigation signals; real-time generation of navigation data; and status monitoring.□ When the R-Mode technology is applied, ships in operation may be provided with real-time position information even when a GNSS signal error or disconnection occurs. Therefore, the bottleneck phenomenon that may occur in a sea route or watercourse crowded with moving ships can be prevented, and the risk of maritime accidents during night operation can be reduced, increasing safety of vessel navigation.□ Furthermore, this technology allows for the utilization of existing maritime communication infrastructure and frequency bandwidth by employing transmitting stations established on the ground, dramatically reducing initial cost of establishing terrestrial infrastructure.□ The R-Mode technology is expected to be applied to various fields, including future ship and maritime mobility, ship berthing, automatic port cargo handling, and watercourse survey.□ Tae Hyun Fang, a principal researcher of the Ocean and Maritime Digital Technology Research Division, said, “As international organizations such as the International Maritime Organization(IMO) require a navigation system that is capable of supplementing the vulnerabilities of GNSS, we will make positive efforts to make our technology an international standard and achieve technological leadership.”□ Keyyong Hong, the president of the KRISO, said, “The maritime position information will gain more importance when smart vessels such as unmanned ships and autonomous ships begin their full operation.” He added, “The KRISO is participating in the development of the position, navigation, and timing (PNT) information service together with the R-Mode technology. We will continue to commit ourselves to the related research to keep the precious life of the citizens as well as the maritime safety.”
