Satellite data unit

Avionics device for geospatial location

A satellite data unit (SDU) is an avionics device installed in an aircraft that allows air/ground communication via a satellite network. It is an integral part of an aircraft's SATCOM system. The device connects with a satellite via ordinary radio frequency (RF) communication and the satellite then connects to a ground station or vice versa. All satellite communication whether audio or data is processed by the SDU.
