Sydney, AU- Threats of cyber-attacks have forced some nations to go back to the drawing board and consider technology from the past, particularly the one used during the World War II.
Ships use navigational systems like the GPS that are vulnerable to hackers because the systems heavily rely on technology. World trade is done using sea transports, which are also susceptible to threats. Ships do not have a backup system in case something goes wrong with the internal technological structure, unlike an aircraft. If the GPS is stopped, a ship might collide with other vessels at sea.
eLoran, an alternative system currently being developed by South Korea, aims to enhance radionavigation structure that is anti-hack – similar to the old technology used during World War II. The US, the UK, and Russia are reviewing the possibility of adapting this technology in their own shipment system.
Last year, South Korea reported hundreds of fishing crafts returning earlier than their schedule due to jammed GPS signals interfered by hackers. South Korea had pinpointed the blame to North Korea, which vehemently denied the accusation.
Minister Lee Byeong-gon of the Ministry of Oceans and Fisheries in South Korea stated that the three sites for eLoran testing are targeted to be operational by 2019. However, the minister stated that the government still needed to communicate with Ganghwa Island residents who are opposing the idea. Apparently, a chunk of the West Coast will be the building site for the 137-meter antenna.
Conversely, many countries have expressed disagreement or hesitations in adapting the same concept in their own system, thus giving a little to no chance of making an international debut in the World War II upgrade. Some countries have already removed or turned off their radio transmitters like Germany, Denmark, France, and Norway. Currently, the UK has only one eLoran transmitter.
