  3. Fundamental Principle of Multilateration 3 / Transponder Reply Aircraft transponders reply or Mode S quitter to interrogations from SSR MLAT/WAM CPS 1 calculates surfaces or multilateration systems, and emit unsolicited of constant time squitters/extended squitters difference 2 Signals received and time stamped Multilateration 3 by Ground Stations Ground Stations 4 (GS) Ground System Output: Track Multilateration communications Aircraft reports Surveillance ATC reports Central network Data Display Processing Processor System Station (CPS) WAM/MLKAT Training Thales Shawnee - Part I Dec 1, 2011

  4. Multilateration 4 / Based on 1090 MHz signals (Mode A/C/S, 1090 ES)  Requires >4 receivers with line of sight to target, or,  at least 3 receivers + baro altitude Geometry-dependent – proper site planning is critical  Transmitter required for Mode A/C compatibility  Multi Multilate latera ration tion System System Con Configura figuration tions: s: MLAT: airport surface surveillance  PAM and TMA MLAT: precision approach monitoring or  airport terminal area surveillance Country-wide WAM: en-route surveillance  (Wide Area Multilateration) Same equipment - same software  Thales Multilateration System: MAGS (Multilateration Air/Ground Surveillance System) WAM/MLKAT Training Thales Shawnee - Part I Dec 1, 2011

  8. Siting Concept  DFS concluded a comprehensive initial site survey presenting a selection of more than 80 sites for tenderers to choose from  Thales identified 34 sites (12 of these for airport GND alone) and their respective role  Main driver: low level visibility, rather than power budget Omni  Re-use existing sites as far as practial Antenna  Requires system adaptability: antenna types, EMC, communication, packaging, lightning protection, etc.  Confirmed findings in final site survey Sector Antenna Omni Antenna 8 PAM FRA Overview - WAC February 2013 - HN

  9. Site selection: Good sites do exist, but... .. ...many .many ot othe hers rs ca came me be before fore – an and d th they ha ey have ve simi similar lar ne need eds  No space on mast  Top position occupied  Strong transmitters  Harmonics close to the 1090 MHz frequency  Icefall may impact antenna‘s life  Daily lightning strikes 9 PAM FRA Overview - WAC February 2013 - HN
