International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT) - 2016. 4514-4517.978-1-4673-9939-5 (e)http://hdl.handle.net/10321/2999In this paper is presented the spacecraft launching technique and different rocket systems. The launch of the satellite and controlling support services are a very critical point in the creation of space-based communication technology and the most expensive phase of the total system cost. At the same time, the need to make a satellite body capable of surviving the stresses of the launch stages is a major element in their design phase. Satellites are also designed to be compatible with more then one model of launch vehicle and launching type. In a more determined sense, the multi-stage expendable and manned or unmanned reusable launchers are described. Owing to location and type of site here are discussed land-based and sea-based launch systems. The new sea launch multinational system was developed more than ten years ago to overcome the cost of land-based launch infrastructure duplication around the world. Additional rocket motors during launching procedure, such as perigee and apogee kick propulsion systems, may also be required.4 penGEOSatellite LauncherHohmann Transfer EllipseSatellite OrbitLaunching VehiclesPresentation
