Spacecraft launching technique and systems

In 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.
