Abstract

This paper reports a study and practical evaluation of two different clock synchronization methods for distributed measurement and control nodes based on Linux Single Board Computers (SBCs) with ARM processors and communicating through a TCP/IP wide area network. First the Network Time Protocol (NTP) is configured and evaluated in different network scenarios. The second solution is a specific development for Global Positioning System (GPS) clock synchronization. After a description of the hardware and software implementation of this solution the experimental results are reported and commented.
