TrueNorth offers unique inflight connectivity solutions that work seamlessly with the Gulfstream fleet, including G650, G550, G450, GIV and GV aircraft. Our reliable, apps-based systems are always up to date and interface with multiple equipment types. 

Solutions for passengers

Every Stylus handset will work every time. Our Optelity family of communication systems offers more channels to choose from and always picks the best available channel. There’s no longer a need to call from a specific handset or remember prefixes for outgoing calls. And best of all, the sound quality is like a face-to-face conversation. Stylus handsets are fully customizable to fit every cabin environment.

Solutions for the flight deck

TrueNorth’s Simphonē FANS-1/A Data Link Unit (DLU) is business aviation’s only FANS over Iridium DLU with FAA, CAN and EASA TSO. Read the news release: Gulfstream offers GIV and GV operators FANS-over-Iridium solution. DLU can be a primary Satcom or a redundant back up. It connects to many flight management systems and requires no configuration once installed. Like other DLUs, our system is ideal for operators flying trans-Atlantic routes. The DLU reduces the crews' workload through a text-based interface that minimizes communication error, while maintaining safety standards and offering flight efficiency. 

TrueNorth is an Approved Gulfstream Supplier.
