muLTElink is a multiple link airborne radio system that combines a DO-377A Link Executive Manager (LEM) with integrated LTE and C-Band command and control (C2) radios plus support for an external ISM C2 radio. muLTElink connects to an autopilot via a transparent RS232 serial interface. muLTElink is plug and play with the George G3 autopilot and the SkyLink915 ISM Band CNPC radio, and it streamlines platform integration by automatically registering aircraft with SkyLine Cloud Managed BVLOS service.
