It is important to minimize handover for robust communication. In earth fixed beam, time that one satellite covers the same area must be considered. In order to consider the service time, the signal to interference plus noise ratio (SINR) should be taken into consideration. In this paper, we analyze the SINR of low earth orbit (LEO) satellite according to elevation angle. Simulation result shows that the average SINR increases when the elevation angle gets larger.
