INTRODUCTION
It is an ADS-497 (Automatic Dependent Surveillance-Broadcast) 1090 MHz Mode S Extended Squitter Ground Station, whose primary function is to receive 1090 MHz Mode S Extended Squitter (1090 ES) messages broadcasted by ADS-497 equipped aircraft (and possibly airport surface vehicles), extract the data contained therein (Position, Height, Velocity, Call-sign, ...), assemble appropriate ATX021 target reports, ATX025 status reports, and optionally ATX023 & ATX247 version reports, and forward these reports to client systems over a data network.
FEATURES
● Providing surveillance redundancy where radar coverage exists
● As stand-by to radar systems to provide supplementary surveillance coverage
● Filling surveillance gaps where surveillances coverage is not possible due to high terrain and remote areas
● ADS-497 data locally integrated with ATM automation systems installed
● Providing Geometric Altitude is useful for RVSM (REDUCED VERTICAL SEPARATION MINIMUM) monitoring, and also as an indicator of correct QNH setting in the aircraft
● ATM operators are able to distinguish between surveillance targets from different type of sensors through different symbols and colors
● Sharing ADS-B data with the neighboring countries
