The progress in the development of high-precision caesium beam atomic clocks gives the opportunity for detecting the hypothetical absolute velocity of the Earth in the terrestrial experiment, using the one-way light pulses. The proposed experiment involves two non-synchronized clocks S and R to be placed at the same latitude far apart within the range of vision. A laser installed near the clock S emits short light pulses at equal time intervals during twenty-four hours, meanwhile the receiver near the clock R registers the times of pulse arrivals. The series of time intervals at the point R will display diurnal variations, which can be used for calculating the equatorial component of the absolute velocity of the Earth.
