The South Korean Army is to receive four of the latest friend-or-foe identification systems from EADS Defence & Security (DS).

The IFF systems, otherwise known as secondary surveillance radars (SSR), automatically send interrogation signals and accurately collect data such as origin, course and speed of an individual aircraft.

The transponders on-board the aircraft will respond to the SSR-sent encrypted signals.

The MSSR 2000 I interrogator satisfies both the latest air traffic control standard mode S and the latest military standard mode 5, which significantly enhances aircraft identification queries.

IFF system records and tracks flight movements precisely to provide a complete picture of air traffic and help avoid traffic collisions or friendly fire in military missions.
