Satellite TDMA controller design for timing acquisition and timing synchronization

A satellite TDMA controller (STC) design for timing acquisition and timing synchronization in satellite TDMA systems is presented; it utilizes a modified open-loop control method in the acquisition process and a closed-loop control method in the synchronization process. Since the modified open-loop control method affords a wide timing margin, the timing acquisition can be securely established. Besides, the closed-loop control method can maintain stable timing synchronization. The feasibility of STC design is confirmed through experiments.
