  • ADS-B

THE WAM/ADS-B radio is the core of a full featured ADS-B ground network integrating all equipment in existing telecommunications networks. It provides redundant network outputs for high reliability surveillance solution.

 

System Description

The ADS-B radio consists of two components: the 1090 radio unit and UAT radio unit. Both units are mountable in a standard 19” rack, operating from -48 VDC power.

The 1090 Radio Unit integrates all communications equipment and a 1, 2, or 4 channel 1090 receiver and 1090/1030 agile transmitter. The 1090 receiver can decode ATCRBS, Mode-S, and ADS-B surveillance replies and squitters, while meeting or exceeding degarbling requirements.

The transmitter supports both generations of TIS-B/ADS-R target uplinks at 1090 MHz and interrogation legacy airborne transponders at 1030 MHz. The 1030 MHz interrogator supports Mode-A, Mode-C, and Mode-S (DF4/5 or DF20/21) interrogations.

The UAT Radio Unit integrates a 1 or 2 channel UAT transceiver with a 1030 MHz receiver. The UAT transceiver operates on the 978 MHz band and receives UAT ADS-B target reports, and generates TIS-B/ADS-R target uplinks and FIS-B uplinks. The 1030 MHz receiver decodes Mode-A, Mode-C, and Mode-S interrogations.

 

Technical Features

    • Supports FAA CAT033 and CAT023, as well as EUROCONTROL CAT021, CAT023, and CAT247 surveillance reports on redundant 1 GBit LAN connections
    • Accepts FAA CAT033 and EUROCONTROL CAT062 target reports for the generation of TIS-B and ADS-R uplinks in either the 1090ES or UAT link formats
    • Accepts UAT FIS-B uplink commands for providing extended data such as weather data or NOTAMs
    • Provides SNMP, SSH, SFTP and web-based maintenance interfaces, supported on both the redundant surveillance LAN ports and a dedicated 1 GBit Maintenance LAN connection
    • Allows basic maintenance to be performed through the available serial maintenance port.

 

  • Multilateration & WAM systems

Multilateration is a field-proven certified technology, addressing some of today’s most challenging surveillance scenarios, from the runways and taxiways of the world’s busiest airports to remote mountain ranges.

FEATURES

    • Multilateration uses multiple (at least three) sensors to calculate the location and identification of an aircraft or vehicle-mounted transponder. Surveillance data output can be fused into an A-SMGCS or en route ATC radar display, or be displayed on its own. Multilateration works with standard Mode S and Mode A/C transponder equipment.
    • Airport Surface. Provides surface surveillance data for Advanced – Surface Movement Guidance & Control Systems (A-SMGCS) or Surface Management Systems such as Aerobahn.
    • Terminal & Wide Area. Provides surveillance in the approach, terminal or en route airspace, or provides surveillance where traditional radar is impractical due to terrain. These deployments are called Wide Area Multilateration (WAM).
    • Special Use Airspace (SUA). Provides surveillance of highly maneuverable, mixed vehicle traffic in restricted (e.g. military) airspace.
  • Test Transponders
    • Continuous verification of Integrity, accuracy, phase and azimuth alignment for the secondary surveillance radars.
    • Available Single or dual channel versions with automatic switchovers.
    • Operating in modes 3A, C and S
    • Fully solid state built in modular construction
    • Directional Antenna

      • Level 3 data link
      • Enhanced Surveillance
      • Surveillance Identifier (SI) capability
      • Provides ability to set specific GICB registers such as Altitude, True Track Angle, Ground Speed and Magnetic Heading.
    • Fulfills ICAO recommendations’ on Mode-S operation, Annex 10 (latest recommendations).
