ERA completes multilateration system extension at Incheon Airport

ERA has extended the multilateration system at Incheon International Airport in Seoul, South Korea

ERA has completed the first extension of the multilateration system at Incheon International Airport in Seoul, South Korea.

Incheon International Airport Corporation (IIAC) has accepted the SAT procedure of the first phase of planned extension and thus the enhanced system has gone fully operational. ERA is currently getting ready to start the second phase of its extension and modernization.

In 2017 ERA installed its multilateration (MLAT) system as part of the A-SGMCS (Advanced Surface Movement Guidance and Control System) for the airport in Seoul, which covers not only the airport area but also 20 nautical miles of TMA.

ERA was contracted by IIAC again last year to extend the coverage of the airport premises due the construction of the airport's fourth runway, new cargo terminal and a number of new aprons. To meet the requirements, ERA delivered a dozen new Ground Stations and has modernised several Central Processing Stations including new servers.

ERA cooperated on the project with a local Korean partner HIST (Hanjin Information Systems & Telecommunications). The second phase of the extension, including the upgrade of the used software, will start in June 2023. The entire project is planned to continue for another 19 months.

The original Incheon project is remembered among ERA experts as an important milestone in ERA technological development due to its pioneering use of the then introduced NEO system, an enhanced version of the ERA traditional product MSS (Multilateration Surveillance System) combining the technology of multilateration, e. g. passive surveillance, with ADS-B sensors. The ERA MSS/NEO system is designed in accordance with all EuroControl standards and as such is used all over the world as part of ATM and ATC solutions ensuring the safety of air traffic.
