JCS_V5_N3_RP2 Modification in Parameters and Improved Analysis of Intersatellite Optical Wireless Communication System Pooja Sharma Sharad Mohan Shrivastava Anuja Mishra Prachi Agrawal Rahul Parganiha Journal on Communication Engineering and Systems 2277-5242 5 3 7 14 (IsOWC) Intersatellite Optical Wireless Communication, Intersatellite Links (ISL), Free Space Optics (FSO), QFactor, Bit Error Rate (BER) The aim of this paper is to analyze a method to connect two or more satellites by using optical link. The first objective of this paper is to design an Intersatellite Optical Wireless Communication System (IsOWC) and this system designed was modeled and simulated for various performance characterizations. The other objective of this paper is to find the relationship between various performance parameters of Intersatellite Optical Wireless Communication System. Several parameters of the IsOWC system are varied to obtain enhanced system performance. The main parameters that was considered is distance between satellites, different wavelength, bit rates, etc. The IsOWC system was modeled and simulated by using Optisystem 14.0 by optiwave software.
