Unmanned Helicopter Airborne SATCOM ST300

Vue d'ensemble

Unmanned Helicopter Airborne SATCOM ST300 Rotorcraft has the characteristics of fast speed, low altitude, flexible mobility and free from geographical conditions, it plays an important role in aerial forest protection, supplies delivery, emergency rescue and disaster relief, search and rescue, and major event security. Based on the design features of communication satellites and combined with the complementary advantages of traditional wide-beam satellites, the general aviation airborne satellite broadband communication service with "high bandwidth rate, wide coverage range and excellent service quality" is launched for each application scenario of rotorcraft. The service realizes the connection with the ground satellite earth station and the ground communication network through the antenna terminal installed on the aircraft, which effectively guarantees the safe production of the aircraft during the operation and improves the operation efficiency. 1) High Integration of ACU Modem and POWER 4) Simplified system structure 6) Remote data monitoring The system has been installed and applied in Eurocopter EC130B4/EC135P2/P2+/EC130T2, Airbus AS350B3/H125 (Squirrel), Bell407 and other aircrafts, meets the application requirements of rotorcraft in aerial tour, emergency rescue, police patrol and other scenarios. GA300 is a satellite communication system designed for small and medium-sized rotorcraft (manned & unmanned) general aviation aircraft, which enables the aircraft to carry out real-time video backhaul, IP calls and broadband Internet access through the satellite during the flight, and has the characteristics of small volume and light weight. As an important part of the satellite communication link, the airborne satellite communication control terminal MODMAN highly integrates the modem (Modem), control unit (ACU), video codec, etc. The terminal has the functions of signal processing, system control, video and voice output.
