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.
