Airborne satellite communications modem 价格:

Details

Key features:

       The airborne satellite communication modem has the ability to automatically detect the rotor and transmit the data rotor gap, and is in the best position among similar products in China. The time occupied by the burst transmission of data is short, and the probability of being blocked by the rotor of the helicopter is low. By rationally designing the frame structure and retransmission mechanism, the transmission efficiency can be improved under the premise of ensuring the reliability of communication.

    On-board modems range in data rates from 32kbps to 50Mbps and use a variety of forward error correction (FEC) methods, including Turbo Product Code (TPC) and LDPC.

    The device adopts modular hardware, which can support a variety of different data interfaces according to the requirements of service loads, and can adapt to various application scenarios.

    Customize the on-board modem according to the installation conditions, interface type, and size requirements of different models.
