In this paper the important method to set up a link between satellites in different types of earth orbits such as Geosynchronous Earth Orbit (GEO) , Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) is inter satellite communication is discussed. As with its merits, there are some demerits also which use have discussed in this paper, but these limiting factors of IsOWS can be reduced by using more efficient techniques. The IsOWC system can be further improved or enhanced by using various techniques such as advanced modulation techniques and diversity techniques. IsOWC link system is best technique to achieve very high data rate.
