The simulation and analysis of background noise effect on inter-satellite link

In this paper, the influence factors of inter-satellite communication, such as background noise, electronic noise, and jitter noise, are analyzed firstly. Then according to the relative position of satellites and background interference sources, a model of disturbance of background noise on satellite communication inter-satellite link, which is relevant to FOV (Field of View), is proposed and the conditions of inter-satellite disturbance is obtained. In order to verify the model, a Iridium constellation simulation is established with STK (Satellite Tool Kit). The simulation result proves that both the model and the analysis method are high-effective in determining the disturbance at any time, which is helpful to select routing of inter-satellite link. 2014 Taylor Francis Group.
