Overview
- Advanced air traffic surveillance unit
- Operates up to 55,000 feet
- 250 watts of transmit power
- Typical active interrogation range of 40 nautical miles in the forward direction
- Recommended for faster & higher-performing aircraft
- Passive surveillance is provided with available 1090 MHz extended squitter ADS-B “in” capability
- Generates both aural and visual traffic advisories
- Expanded aural alerts can specify relative target bearing, relative altitude (above/below) and range
- Tracks up to 60 traffic targets simultaneously
- Displays up to 30 intruder threats
- Selectable horizontal display ranges
- Interfaces with a variety of compatible MFDs and cockpit displays
- Selective/directional interrogation reduces frequency congestion
- High-Speed Data Bus (HSDB) or ARINC 429 interface capability
- Vertical or Horizontal LRU rack mounting
- 14/28 VDC power capability
- Basic system consists of transmitter/receiver computer LRU, 4-channel GPA-65 power amplifier/low noise amplifier (PA/LNA) that is remotely installed near the top directional antenna to boost antenna performance
- Typical installation includes both top-mount directional and optional bottom-mount antennas to reduce the potential for antenna “shading” of TAS interrogations – shading can cause targets to drop out during turns or maneuvers, or when the threat is positioned directly below
