ADS497 Automatic Dependent Surveillance-Broadcast

Additional information

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 surveillance 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 types of sensors through different symbols and colors
Sharing ADS-B data with neighboring countries
