Applications of satellite communications has broader usage; for instance voice, video calling, internet, fax, television, and radio communications. There are abundant and various types of satellites that has applications from amplification of radio telecommunications to military applications and most importantly its application are globally and it also allows transmission of high amount of data.In this paper various types of advanced satellites are discussed; some of them are quantum communication through satellites, metamaterials for better satellite antennas, National Aeronautics and Space Administration's (NASA) laser communications, ZigBee based inter-satellite communications, quantum encryption network through satellite
