Unmanned Helicopter Airborne SATCOM ST300
Details
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.
