how do satellites get into space

To launch an artificial satellite in space, multi-stage rockets are used. It raises the satellite to a predetermined height, projects it in the right direction with a velocity which enables it to revolve around the Earth. This velocity is called the escape velocity. E..

Communication satellites are normally geostationary satellites. They have devices called transponder which receive signals from an earth station and transmit them in different directions. The signals in the form of electromagnetic radiation are transmitted from the earth station..

(the portion of the atmosphere closest to the ground). Frequencies below the HF range travel around the curvature of the Earth, sometimes right around the globe. These ground waves, or surface waves as they are called, are one of the two original means of beyond- the- horizon propagation. All broad..

Expertise is required in the planning, designing and fabrication of satellites. Each satellite has to be designed according to the purpose for which it is used. Also, one should have the basic infrastructure to fabricate the parts of the satellite with high degree of p..

To place a satellite into orbit it needs to be accelerated in several stages. The required acceleration is produced by firing rockets at various stages of flight. These rockets are fitted into a system called 'launch vehicle' which carries the satellite..
