0.6m Low profile STOM system

System composition

 Flat panel on the move satellite communication antenna consists of antenna unit ( including plastic plat panel reflector, waveguide feed network) ,                antenna radome, inertial measurement system, servo control system ( including pedestal, HF joint, motor and driver as well position sensor), control            master, signal, control and power interface ,with such features as high efficiency, compact structure and high tracking accuracy etc. 


System feature

1. Superior electrical performance of antenna. 

2. Plastic plating horn array antenna: Produce in batches with light weight and high gain.  

3. Not rely on GPS information: The satellite beacon tracking is used to correct gyro error and can work normally without GPS information(Only local               longitude and latitude is input manually for one time before initial pointing to satellite).

4. Fast initial pointing, high tracking accuracy, short blockage recovery and fast satellite switchover. 

5. Good stability result,the azimuth adopts closed loop stability algorithm and fast transfer or "S" travel and can still track accurately satellite.  

6. Convenient use: Can achieve dynamic pointing and dynamic satellite switching etc.  

7. Convenient maintenance: System module design,simple interface specification and convenient fault  diagnosis and maintenance.  

8. Convenient integration: Only such four external interface as data output, DC supply ,intermediate receive and transmission and the connection                      relation is simple.
