Analysis of GEO intersatellite laser time transfer and link performance

The laser time synchronization is one of the developing field of future intersatellite time synchronization. This paper studied the GEO intersatellite laser time synchronization method of Compass I and gave two modes of GEO intersatellite laser time synchronization. According to the GEO satellite parameters of Compass I and in the condition of a given transmission system, link parameters and transmission loss and other conditions, this paper analyzed the relationship between satellite transmit power, antenna diameter and intersatellite transmission rate of GEO intersatellite laser link. The result provided a reference for GEO intersatellite laser time synchronization.
