ABSTRACT

In this paper we propose a technique for comparing timelines on a laser ranging station (LRS) and Earth artificial satellite (EAS). By fixing time instants of three events (the laser fire, its reflection from the satellite reflector and detection of satellite echo at the station) we get the system of equations to connect the parameters measured in the satellite laser ranging with the time bias between the station and the satellite. The method to solve this system is proposed. Consideration is given to the assumption about the correction to the speed of light in the near-Earth space. The system of equations obtained connects the value of this correction with the time bias between the LRS and the satellite. We propose a method to estimate these two values. A possibility to check the relativity theory in this experiment is also considered.
