| Abstract: | The antenna servo control system for a satellite antenna is introduced. The system is based on FPGA. The system converses the given steering angle instruction form the computer into pulse and smoothly rotates antenna to the specified location. In the same time, the rotate and converse module feed the actual angle of the antenna back to the servo system. The antenna motion tracking and pointing functions are implemented. |
