Abstract:
It is important to maintain a traceable source of timing information as it is used in many applications. National timing laboratories of different countries are responsible to generate and maintain precision timing based on atomic and/or optical standards. Generally, an ensemble of clocks is used with a time scale algorithm that ensures a stable time compared to a single atomic clock. Time scale algorithms vary based on the techniques used to assign weights to the participating clocks. Two of such methods are compared in this paper. For an ensemble consisting of both Hydrogen-Maser and Cesium atomic clocks, it is found that the results of a fixed weight assignment method are comparable to the results of the existing AT1 method.
