ACSS Offers NXT-700 ADS-B Compliant Transponder for Legacy Corporate Aircraft

ACSS, an L-3 and Thales Company, has developed an ADS-B transponder solution for legacy corporate aircraft, the NXT-700. This next-generation Mode S transponder will satisfy the DO-260B mandate for Automatic Dependent Surveillance-Broadcast (ADS-B) on many legacy aircraft models and will reduce owner/operator costs, as well as downtime, because it is a “one-quarter ATR short” form-fit installation.
