The significant progress is observed lately in the optical satellite communications: the laser link capacity, in particular the intersatellite laser link capacity, increases many times together with the reduction of both the onboard laser communications terminal mass and the dimension of optical apertures. For considered period by using European geostationary relay satellites ARTEMIS and AlphaSat I XL, a number of low earth orbit spacecrafts and ground stations many experiments was carry out on the communication between above mentioned objects and was study the atmosphere influence on quality of the service. Obtained information may be useful for designers of future data relay satellite systems.
