MLAT1290 MLAT Surveillance System

Description

 INTRODUCTIONMLAT1290 (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.   SPECIFICATIONS●      High accuracy and updated rate capability.●      High Reliability and Accessibility●      Good coverage and precision in large airspace●      Modular structure and state of the art design technologies.●      Fast and remote upgradable●      Fully redundant system design.●      Built in Test capability.●      Low power consumption.●      Low cost maintenance.   TECHNICAL SPECIFICATIONS ●      Processed Signals : Modes 1,2,4, 3/A,C,S including ADS-B●      Position Accuracy <100 m in coverage area <7 m in Terminal area●      Target Capacity: Up to 1500 targets●      Track Initiation< 5 seconds●      Update Rate: Configurable between 1-4 sec, if response is available●      System Latency: 250 ms●      Data Formats: ASTERIX, SNMP   RX STATION●      Channel: 1090MHz●      Bandwidth: 8MHz●      Sensitivity: -92dBm●      Reply Type: Mode A/C, IFF modes1,2,4, Mode S, ADS-B   ENVIRONMENTAL CONDITION●      Outdoor units is -40° C to +70° C●      Indoor units is 0° C to +50° C
