Fixed Wing UAV Airborne SATCOM ST280

 Fixed Wing UAV Airborne SATCOM ST2800

The fixed-wing airborne satellite broadband communication system is based on communication satellite resources, combined with RF transmission equipment, baseband modem equipment, network equipment, and terminal data acquisition equipment to establish a communication connection between the aircraft and the satellite hub, enables the aircraft in any flight area to carry out real-time image and video backhaul, voice calls，data transmission and other applications.

Applicaiton
The system has been installed on Cessna 208B, Y5, Y12, Y12E, Diamond DA42, GA-8 and other models to achieve installed applications. The system has a wide range of application scenarios and can be applied to forest fire prevention, power cruising, and border surveillance, geographical mapping, Man and Weather, etc.

VSAT Technical Parameter
GA280 is a satellite communication system designed for small and medium-sized fixed-wing (manned & unmanned) general aviation aircraft. The system can effectively enhance the communications security capability of general aviation aircraft, allowing the aircraft to maintain real-time satellite communication in any flight area, and it can perform functions such as real-time video backhaul, IP calls and broadband Internet access via satellite. It has the characteristics of small volume and light weight.
