    Ka-2 Series Marine Satellite Communication Antennas

    Classification:VSAT networking

    Linkman:Sandy

    Mobile:17327835419


    Application

    Ka-2 series satellite TV antenna on board has the characteristics of high reliability and superior performance. It is suitable for areas where the elevation of the target satellite is less than 85 degrees. It is widely used in official ships, engineering ships, merchant ships, yachts, oil platforms, fishery ships, etc.


    Functions


    High accuracy and stability: The antenna has built-in MEMS angular velocimeter and accelerometer. The geographic position information is obtained by GPS and the azimuth, elevation and polarization angles are calculated by MCU. The antenna can be quickly aligned and tracked to the satellite; the sensor data are processed by adaptive Kalman filter; and the control frequency is guaranteed by the high resonance frequency pedestal.

    Automatic Polarization Control: According to GPS information, the controller constantly updates the polarization angle to achieve the optimal control of the polarization angle. This function is very suitable for ships on East-West routes.

    Global applicability: In order to adapt to different satellite signals, antennas can be adapted to a variety of LNB (down converter), thus adapting to global applications.

    Reliable quality: industrial-grade components are used to ensure the reliability of components; software, built-in coordinate transformation module, PD stability module and other core modules, whose control frequency is more than 200 Hz; production technology, using long-term high and low temperature aging test.
