0.3m Ku band Helicopter/Fix wing Airborne VSAT Antenna
SATPRO helicopter airborne satellite communication system consists of VSAT, MODMAN and the Modem in hub station, the problem of helicopter rotor block can be solved adaptively. The VSAT antenna adopts integration design, with independent intellectual property rights of the inertial navigation measurement fusion algorithm, the high-performance waveguide horn array antenna will always point to the satellite accurately through the stability of the servo platform. It allows the aircraft has the uninterrupted communications during flight via satellite. It has the functions of real-time back of electro-optical pod video, IP telephone call, data acquisition back, the engine room wireless WiFi, etc. It helps the aircraft to complete forest fire prevention, emergency support,disaster warning, aerial reconnaissance and other tasks.
As an important part of helicopter satellite communication link, SATPRO integrates the Modem, Power ,Codec and Antenna Control Unit (ACU) in one unit, which is highly integrated airborne satellite communication control terminal (MODMAN). The control terminal has powerful functions such as modem management,antenna control, signal processing , power supply and etc, the operation is efficient and simple, and the space inside the aircraft is effectively saved.
