ADS497 Automatic Dependent Surveillance-Broadcast

Description

INTRODUCTIONIt 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   TECHNICAL SPECIFICATIONS●      Processed and Decoded Signals: Modes S DF = 17, 18, 19 compliant to ICAO Annex 10, Doc 9871, RTCA DO- 260/A/B, EUROCAE ED-102/A●      Target Capacity: Up to 1500 targets●      Update Rate: 0.5 sec●      System Latency < 250 ms●      Data Formats: ASTERIX Cat 21 & 25 & 247 & 23●      Sensitivity at antenna port better than -90 dBm●      Range: 250NM●      SNMP controlled●      Operating temperature: -40 ~ +70 °C●      Ingress protection: IP 52
