Comparison of Different Time Synchronization Techniques

R. Kaarls, G. de Jong

Abstract:	The Van Swinden Laboratory (VSL) of the National Service of Metrology in the Netherlands has recently been moved to a new laboratory at Delft. The section Time and Frequency of the Division of Electromagnetism and Time is now housed in a laboratory, built as a cabin of Paraday, with well-maintained environmental conditions and equipped with different other provisions. The cesium atomic clocks are put on heavy concrete blocks which are placed vibration free at sufficient distance from other objects to avoid mutual disturbing influences. A microprocessor provides the automatic data registration of the complete system. The main international synchronization link is the Loran-C system. Initially it was planned to set up an international TV-synchronization network between NPL/RGO, LPTF, PTB/DHI and VSL. For this purpose three 3 m-parabolic antennas should be placed at 90 m height on top of the main building of the Department of Electrical Engineering of the Technical University Delft.
