Abstract

Control network of active surface using Precise Time Protocol operates the actuators. PTP network structure, principle of synchronization and model of clock servo are elaborated. The protocol stack with PTP is running on Actuator controller. This scheme is used to real-time control in active surface of radio telescope.
