INTRODUCTION

MLAT1290 (Multi Late Ration) is a surveillance system that receives and locates transponder and other transmissions radiating from aircraft on various frequencies, typically 1090 MHz the frequency used by IFF, SSR, Mode S and ADS-B transponders. Nowadays, these same techniques are used for larger areas such as en-route or approach areas. Such systems are called Wide Area MLAT (WAM) systems.

An MLAT system detects, locates, and identifies cooperating targets by receiving and processing suitable signals emitted by on-board transponder devices, according to the SSR international standards. In MLAT systems, receiving stations are placed in some strategic locations around the area to be covered.
