1.2M vehicle driveaway antenna is mainly installed in the vehicle carrier and start to work when the vehicle stops
Description:
The vehicle driveaway antenna can be effectively received as long as it is under the effective coverage.
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 system is composed of antenna surface, feed, antenna support platform and servo mechanism, and the star control system and so on. It has the advantages of small volume, light weight, high reliability, high reliability, high reliability, high reliability, Easy to operate and so on.
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 according to the satellite beacon signal or DVB-S carrier Signal to capture the satellite scan.
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, The vehicle driving antenna uses an advanced control platform, friendly man-machine interface, simple operation, to realize a key to acquistion. The whole process to start, position, capture the satellite can be completed within 3 minutes, fully meeting the requirements of emergency communications systems with supporting manual acquistion (for fine tuning) and automatic calibration satellite communication antenna azimuth, polarization, pitch and electronic compass function. In the process of acquistion in the event of a sudden power failure, people can also know the current attitude of the antenna after restoring the power supply.
