“Catching Radio Interference in the New Space Era” KT SAT Enhances Honsinwon Detection System

KT SAT Enhances ‘GEOLOCATION’ Intrusion Detection System Using Two Mugunghwa Satellites

[Asia Economy Reporter Eunmo Koo] Satellite communication company KT SAT announced on the 10th that it has enhanced its 'Geolocation (GEOLOCATION)' system to strengthen its capability to quickly detect radio interference during satellite communications.

The GEOLOCATION system is a solution that uses KT SAT's two Mugunghwa satellites to locate the transmission source of unidentified interference signals. It analyzes the differences in time and frequency values (differential values) of interference signals received at each location by Mugunghwa satellites 5A and 6 to pinpoint the exact transmission location of the signal.

Recently, the competition for dominance in space business among global private companies such as Tesla's SpaceX and Amazon's Project Kuiper has intensified. They launch numerous low Earth orbit satellites (LEO) in clusters to build a global satellite internet network. Consequently, dealing with communication disruptions caused by radio interference between satellite networks has become a critical issue in the industry.

In response to this trend, KT SAT has upgraded its GEOLOCATION system. In January, KT SAT completed the enhancement of the interference source detection system within the GNOC (Global Network Operation Center) of the Satellite Consulting Division and successfully finished all verification processes after two months of pilot operation.

Previously, when interference signals occurred, the process involved comparing signals based on past receiver records or confirming individually with clients. This cause analysis method, relying on past experience, took a lot of time and made it difficult to immediately determine whether the disruption was due to customer negligence or transmission equipment malfunction.

KT SAT expects that the introduction of the GEOLOCATION system will significantly reduce the time required to detect interference signals. A KT SAT representative explained, "Currently, the system shows high efficiency in locating the earth stations causing interference signals and the equipment generating abnormal transmissions," adding, "Since rapid response is crucial in communication disruptions, this advancement is very meaningful in terms of improving customer satisfaction."

Song Kyung-min, CEO of KT SAT, stated, "We will actively collaborate with overseas satellite operators to strengthen our ability to analyze unidentified interference signals transmitted worldwide," and added, "We will strive to improve the quality of Mugunghwa satellites and enhance global customer satisfaction by quickly identifying and resolving radio interference causes."
