Abstract

This paper provides the details of a study on the effects of electron radiation on the Performance of Inters-satellite Optical Wireless Communication (IsOWC). Academia and industry focus on solutions that can improve performance and reduce the cost of IsWOC systems. Spacecraft, space stations, satellites, and astronauts are exposed to an increased level of radiation when in space, so it is essential to evaluate the risks and performance effects associated with extended radiation exposures in missions and space travel in general. This investigation focuses on LEO, especially in the near-equatorial radiation environment. Radiation experiments supported with simulations have made it possible to obtain and evaluate the electron radiation impact on optoelectronics at the device level and system level performances. The electron radiation has induced a system degradation of 70%. This result demonstrates the importance of such an investigation to predict and take necessary and suitable reliable quality service for future space missions.

Highlights

Some measures have been launched to improve the Inters-satellite Optical Wireless Communication (IsOWC) networks to ensure dependability, flexibility, and a large and efficient broadcast
With the advantages of higher data transmission rates, lower payload power requirements, and smaller terminal size and weight, inter-satellite wireless optical communication (IsOWC) systems have been extensively researched in all aspects to enhance state of the art, such as increasing the speed of transmission by incorporating different wavelengths and modulation techniques [5], or increasing the bandwidth and reduce the cost [6], where the findings suggest that IsOWC could be one of the best alternative ways to meet the growing demands of future high-speed transmission with massive data in space [7,8,9,10]
All devices are commercial on the shelf (COTS), where they are chosen based on their manufacturing materials and wavelengths in concordance with the specifications of the IsOWC systems applications

Summary

Introduction

Some measures have been launched to improve the IsOWC networks to ensure dependability, flexibility, and a large and efficient broadcast. With the concept of the implementation of the space-aerial-terrestrial integrated 5G network (SATIN) and the rapid expansion of ubiquitous mobile services, next-generation wireless communication systems, such as beyond 5G (B5G) and 6G systems, will face formidable challenges posed by the need for a large number of concurrent services with extremely high connection density [3, 4]. IsWOC could be flexible to accommodate the key features of the future 6G communications, where high security, secrecy and privacy suggested to be the main concerns, besides the new communication scenarios in future network which encompass holographic calls, flying networks, teleoperated driving and the tactile internet and many others [11]
