Product overview

The NXG-900 from ACSS (an Acron Aviation and Thales joint venture) provides critical aircraft information including position, velocity, and ground track for ADS-B Out messages. Its versatile design allows signals from the GPS satellite constellation and Satellite-Based Augmentation System (SBAS), including Wide Area Augmentation System (WAAS), as well as other systems. This commercial off-the-shelf package is used with one or two ACSS NXT-600, NXT-700 or ATDL Mode S transponders to provide legacy aircraft operators with a simple path to satisfy ADS-B mandates. It will also work with select 3rd party transponders.

  • Rule-compliant WAAS position source
  • ADS-B In providing 978 MHz UAT, Free Weather (FIS-B)
  • Wi-Fi dongle interface module to compatible mobile applications
  • Certified to TSO-C145c, -C154c and C157a

The NXG-900 provides an ARINC 743A based output, while meeting the Part 25 aircraft environmental levels.
