NXT-600/-700/-800™

ADS-B Mode S Transponder

Description

Ready today to meet tomorrow’s NextGen mandates.

L3Harris’ Mode S Transponders meet the future needs for optimized flight and Air Traffic Modernization efforts for helicopters, business jets and regional aircraft by providing NextGen Automatic Dependent Surveillance – Broadcast (ADS-B) capabilities they need to operate safely and efficiently. The NXT family reduces lifetime costs and improvides reliabiliity as well as enable pilots to take advantage of more efficient routing while increasing airspace capacity, situational awareness and overall operational safety. Additionally, the high-reliability of the units enhances the overall surveillance system by reducing TCAS no-fault-found
failures.

  • Elementary and Enhanced Mode S surveillance-compliant
  • Function validity verification through simple built-in test and self-test capabilities
  • Compatible with all ARINC 735B/735A/735 TCAS II systems, including ACSS TCAS 3000SP™, TCAS 2000™, T2CAS™ and T3CAS™
  • Meets all civil, commercial and military aircraft and rotorcraft requirements with two form factor options for slide-in replacement of current XS-950 (4 MCU), RCZ-852 and 1/4 ATR Short

NXT-600™ for Business Jets

L3Harris’ NXT-600™ Mode S Transponders is ready to provide corporate and legacy business jet manufacturers and owners with all the capabilities they need to operate safely and efficiently in NextGen Automatic Dependent Surveillance – Broadcast (ADS-B) airspace. Optimized for NextGen operations, the NXT-600™ enables pilots to take advantage of more efficient routing, while increasing airspace capacity, situational awareness and overall operational safety.

The adaptor tray also enables quick and easily replacement of the Rockwell Collins TDR-94 and TDR-94D systems.

NXT-800™ for Regional Aircraft

Mode S Transponder designed to maximize space and provide pilot efficiency and situational awareness.

Features

Highly accurate position reporting

High-level of ADS-B Out (DO-260B) reporting requires the transmission of precise, real-time flight data information, including current aircraft position, speed and intent. The NXT-600 automatically transmits all position data via ADS-B Out to other nearby aircraft (equipped) and Air Traffic Control (ATC).

NextGen ADS-B compliant around the world

L3Harris NXT transponders are DO-260B-compliant to meet NextGen & Standardized European Rules of the Air (SESAR) mandates requiring transmission of more precise position, speed and intent data. They also meet ICAO Level III standards for the latest functionality for the ICAO Airborne Collision Avoidance System (ACAS) II mandate and are also compliant with European Elementary and Enhanced Mode S Surveillance Downlink of Aircraft Parameters (DAPs) and ADS-B 1090ES extended squitter.

Software upgradability yields reduced maintenance costs

The capability to perform timely onboard software loads provides operators with simplified upgrades, increased aircraft utilization and lower maintenance costs. In addition, the high reliability of the NXT-series greatly enhances the overall validity of the TCAS system reducing Mode S transponder-induced No-Fault-Found (NFF) TCAS failures.
