In the past it was usual to exert a huge effort in the design, simulation, and the real time implementation of the complicated electronic and communication systems, like GNSS receivers. The complexity of the system algorithms combined with the comple

Coordinated Universal Time (UTC) is generated through transferring the time data of hundreds of atomic clocks to the Bureau international des poids et mesures (BIPM). Time transfer using the Global Navigation Satellite Systems (GNSS) is one of the mo

Almost all time keeping laboratories maintain the 5071A Cesium (Cs) frequency standard for generating their national time scales. The frequency stability of this standard is limited by different types of noise, especially the White Frequency Modulati

Improving the stability of national time scale (TS) is a main target for all time keepers. The stability of TS can be improved by either increasing the number of atomic clocks in the ensemble or by adding clocks of higher stability. In both cases, a

Enhancing the frequency stability of the national Time Scale (TS) is a main target of all time keeping laboratories around the world. The Empirical Mode Decomposition (EMD), as a new adaptive simple signal processing technique, is used previously for
