Grouping of a set of SSR Mode S stations into functional entities called clusters has significant operational facets; it calls for a constrained optimization, an important significant constraint being the scarcity of Interrogation Identifier codes. This problem can be approached by two ways, i.e., integer programming methods and heuristic approaches. The definition of a general, usable decision support...
The "multilateration" (MLAT) system is a surveillance and identification element of the A-SMGCS using the SSR transponder (Mode S or even A/C) reply/squitter as signals received by fixed stations where the time-of-arrival (TOA) is measured. In a central processing unit, the target position is estimated by the TDOA technique (time difference of arrival), for which a station is assumed to...
There is an increasing interest on the various applications of the SSR Mode S (secondary surveillance radar - mode selective) for air traffic and airport traffic management. This paper discusses the applications of ICAO standard Mode S signals, in particular in the down link channel around 1090 MHz, to locate and identify cooperating targets in the airport using multilateration (MLAT) and in the terminal...
