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.

This paper proposes the Optical Wireless Communication (OWC) for different Application, Advances and Challenges as high data rate multimedia services are evolving continuously and exponentially increasing the demand for wireless capacity 5G generation and upgrading Technologies. These are used to bypass the RF transmission band, which is inadequate to meet the demand for future high data rate 5G services. It offers services for both indoor and outdoor application as well as in the submerged area with contact distances ranging from nm to more than 10,000 km. This paper provides an overview and performance analysis of technical communication involving Visible light, Line of sight underwater, free space, optical communication, optical camera communication and light detection for all surveys of keys understanding technologies (OWCs) and presents them as aspects of criteria such as spectrum use, application, design, classification advances and challenges.

AbstractFree-space optical (FSO) communication has the advantages of two of the most predominant data transmission technologies – optical fiber communication and wireless communication. Most of the technical aspects of FSO are similar to that of optical fiber communication, with major difference in the information signal propagation medium which is free space in case of FSO rather than silica glass in optical fiber communication. One of the most important applications of FSO is inter-satellite optical wireless communication (IsOWC) links which will be deployed in the future in space. The IsOWC links have many advantages over the previously existing microwave satellite communication technologies such as higher bandwidth, lower power consumption, low cost of implementation, light size, and weight. In this paper, modeling and performance analysis of a 10-Gbps inter-satellite communication link with two satellites separated at a distance of 1,200 km has been done using OPTISYSTEM simulation software. Performance has been analyzed on the basis of quality factor, signal to noise ratio (SNR), and total power of the received signal.
