  Abstract

There is a growing interest in providing telecommunication services to the world through an low earth orbit (LEO) satellite network. In order to exchange data between nodes in an LEO satellite network, laser communication technology is required. Since the inter-satellite laser communication link has a very long transmission distance, the reception sensitivity of the optical receiver is important for link connection. In this paper, we propose an optical receiver structure suitable for implementing LEO inter-satellite laser communication links. Considering the characteristics of the LEO inter-satellite laser link system, the link budget is calculated and the required reception sensitivity is derived. We evaluate the performance of an avalanche photodiode (APD) based optical receiver and an optically pre-amplified receiver to satisfy the derived reception sensitivity, and confirm their applicability to low-orbit inter-satellite links by analyzing the maximum transmission distance.
