Now Available For Pairing With L3’s NXT Transponder Series
NextGen avionics leader FreeFlight Systems announced today that the Company’s 1203C SBAS/GNSS sensor is approved for installation with L3’s NXT Mode S transponder series. Stevens Aviation recently announced an Approved Model List (AML) Supplemental Type Certificate (STC) for ADS-B Out installations across a wide range of Part 25 aircraft after the Company’s first successful install in a Citation 650. This product pairing provides legacy aircraft a complete and cost-effective way to equip with ADS-B for the upcoming mandate.

The FreeFlight Systems 1203C SBAS/GNSS sensor is a certified, high-integrity position source in a compact, lightweight package. The 1203C pairs seamlessly with certified Mode S Extended Squitter transponders like the L3’s NXT series to provide a fully rule-compliant ADS-B Out system.
With several hundred 1203Cs in service today across airline transport, military, and business aviation platforms, these receivers are characterized by their high performance, ease of installation, operational reliability and longevity. The 1203C can also serve as as the approved position source for TAWS/FMS, RNP, and other NextGen applications, and allows customers to take advantage of the operational and safety benefits provided by the NextGen airspace transformation without the need for extensive and costly avionics upgrades.
"We're pleased to partner with Stevens Aviation on this program," said Pete Ring, FreeFlight Systems' Vice President of Sales and Marketing. "We design our high-integrity solutions to be modular and integratable with various other manufacturers, giving our clients affordable and practical ADS-B solutions for whatever they fly."
With the ADS-B mandate now only 23 months away, business jet operators need to prioritize ADS-B installations during routine aircraft maintenance. Significant portions of today’s business jet fleet will remain in service long after 2020, and in many cases an STC’d retrofit solution comprising of a transponder upgrade and the addition of a dedicated GNSS receiver like the 1203C is the simplest and most cost-effective way to achieve mandate compliance.
