TIME SYNCHRONIZATION VIA OTS-2
The report describes the results of a project on time synchronization via OTS-2 satellite between several national laboratories, carried out in 1982. The measuring principle has been based on the application of a one-way method, which means that only the satellite transmits a reference pulse. This pulse is received by all the participating ground stations and the time of arrival is measured. A pilot laboratory computes from these measuring data and from the coordinates of the satellite and the receiving stations and time scale differences. It is shown that uncertainties of 20 ns can be achieved. However, the average accuracy obtained during this experiment was about 300 ns, mainly because the satellite position was not known well enough and because the delay times at the receiving stations were not determined accurately enough. Suggestions are made for improving the accuracy.
