General Description of 0.9m Satcom On-The-Move antenna
The 0.9m Parabolic Antenna On-The-Move antenna system is developed for mobile satellite communication needs such as vehicle, ship, aircraft. The system uses gyro pointing and beacon tracking combination technology, so the product has the advantages of rapid capture, easy operation and high precision of tracking.
The design of the antenna system is scientific and reasonable, which not only has good strength and rigidity, meeting the requirements of vehicle vibration and impact, but also has light weight, low power consumption, and easy loading. The performance fully meets the requirements of GJB2383-95.
Features:
● All operations automatically without human intervention
● Initial acquisition time <120s
● Automatically track satellite in the motion or static state
● Vehicle moving speed can be more than 350Km/h
● Gyro orientation + beacon tracking mode
● Special plastic with light weight and other advantages
