Product overview
ACSS (an Acron Aviation and Thales joint venture) 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 enables pilots to take advantage of more efficient routing which results in 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
Aviation Communication & Surveillance Systems (ACSS)
Aviation Communication & Surveillance Systems (ACSS) is a joint venture between Acron Aviation and Thales. ACSS designs and manufactures products for all aircraft and helicopter segments, and supports products for air transport and regional airlines, business aviation, and helicopter, general aviation, manned and unmanned military aircraft operators. ACSS produces avionics systems that increase safety, situational awareness, and efficiency for commercial and military flight operators.

Key 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
Acron Aviation 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.
Model overview
Acron Aviation’s NXT-600/-800™ Mode S Transponders are ready to support civil, commercial and military aircraft and helicopter manufacturers and owners.
