Description:
Vehicle Satellite Communication Antenna is a mobile antenna, installed on the roof or mobile equipment, suitable for radio, satellite TV, wild and emergencies and other fields
Advantages:
1, The kind of satellite communication antenna is mainly installed in the vehicle carrier, and start to work when the vehicle stops.
2, the vehicle satellite communication antenna system is developed for emergency satellite communication system. The system consists of antenna surface, feed source, antenna support platform and servo mechanism, and so on. It has the advantages of small volume, light weight, high reliability and easy operation.
3, After the antenna system reaches the target location, the control system will locate and orientate through GPS and electronic compass, and adjust the pitch and azimuth and polarization of the antenna according to the calculated satellite data and capture and scan the satellite according to the satellite beacon signal or DVB-S carrier signal.
4, The mechanical part of the automatic vehicle satellite communication antenna system adopts advanced mechanical transmission technology. The azimuth, pitching and polarization motor adopts DC motor and precision reducer to ensure the smooth, reliable and flexible transmission of the vehicle satellite communication antenna.
5, Vehicle satellite communications antenna system uses an advanced control platform, friendly man-machine interface, simple operation, can achieve a key to the star. The whole start, positioning, capture the satellite process can be completed within 3 minutes, fully meeting the requirements of emergency communications systems. While supporting manual finding star (for fine tuning). With automatic calibration satellite communication antenna azimuth, polarization, pitch and electronic compass function. In the process of seeking the system in the event of a sudden power failure, restore the power supply system can also know the current attitude of the antenna.
