Control Research Of Marine Satellite Antenna Servo System

Along with the completed and development of China’ BDS, and lead to the development ofthe study of the Marine satellite antenna servo control system. The key technologies of theMarine satellite antenna servo control system is the stabilization and tracking technology whosekernel is the initial alignment and automatic tracking technology of antenna toward satellite. Thecompleted of automatic tracking technology based on the initial alignment, the antenna move asingle step to automatic track the target satellite based on the completed of the initial alignment,it is will fail if lack one of the two steps. When the satellite signal is weaken for the inference ofthe shelter, device failure and so on,in order to get the signal again to realize to catch the satellite,we need the message of the GPS\BDS and the gesture sensing system to calculate the star pointthat based on the table platform, so we can adjust the antenna catch the satellite again by drivingthe actuator. It is the main purpose to complete the automatic scan-tracking make the connectionof the antenna and satellite be established depend on the message of the gesture and the satellitesignal.We take the form that unite the program-tracking and the step-tracking to realize to catchthe satellite by scan-tracking, and discuss the design of the scheme as a whole, the hardwaredesign and testing of the controller, the software design and debugging of the system. At last,some problems that occurred during the debugging and the working tighter with the next step ofthe work are pointed out.
