there were numerous equipment upgrades during the phase, including the newer and better ASDE-X with MRI (Multi Radar Tracking) function, and the ADS-B (Automatic Dependent Surveillance-Broadcast) system with the RIMCAS (Runway Incursion Monitoring and Conflict Alert System) function. The installation of four additional sets of ASDE-X antennas is planned to reduce blind spots during heavy rainfall and in preparation for the new runway.
