Garmin GDL 88 ADS-B Transceiver

This specific part number designates the remote-mounted, standalone Garmin GDL 88 Universal Access Transceiver (UAT) configuration built without an internal WAAS GPS engine. It serves as a dual-link data node engineered to bring full NextGen ADS-B "In" traffic and weather visualization alongside standard ADS-B "Out" position tracking to compatible cockpit flight displays. Because this variant lacks an internal WAAS sensor, it relies entirely on receiving external GPS position parameters from an approved onboard navigator (such as a Garmin GTN or WAAS-upgraded GNS series unit) via digital data streams.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 7/21/2026.

Key Technical Capabilities
  • Dual-Link Surveillance Coverage: Intercepts both 978 UAT and 1090 MHz transmission streams simultaneously. This gives the flight crew comprehensive, localized traffic pictures by processing direct air-to-air tracking signals alongside terrestrial rebroadcasts.
  • Subscription-Free FIS-B Weather: Continuously decodes 978 MHz Flight Information Service-Broadcast (FIS-B) datalinks, translating weather telemetry straight into graphical NEXRAD radar overlays, METARs, TAFs, PIREPs, and winds aloft maps on compatible multi-function displays. 
  • Target Shadowing Mitigation: Employs advanced internal filtering algorithms to identify own-ship traffic “shadows,” preventing close-proximity transponder echoes from mistakenly triggering phantom collision alerts in the cockpit.
  • Centralized Display Fusion: Interconnects via high-speed ARINC 429 or RS-232 serial interfaces to feed traffic and environmental data layers straight into core flight decks, including the Garmin G500/G600 matrices, GTN series touchscreens, and vintage GNS 430W/530W boxes.
  • Traffic Display Integration: Capable of pairing alongside active onboard active traffic systems (TAS/TCAS I), fusing digital ADS-B targets and active radar paints onto a single consolidated screen to reduce pilot scanning confusion.
