conclusion for space communication

Conclusion - Unfolding the mysteries of the dark and silent space with no known boundaries has always been a dream of the human race. The desires of man has ultimately been accomplished through the exploration of space using various space launching vehicles, ..

Propagation of EM Waves in Atmosphere - In an Earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself. Since the various methods of propagation depend largely on frequency therefore the complete electromagne..

Anything that we look around us has mass and occupies space. Most of the things we use are in solid state. Solids have always attracted considerable interest because of their symmetry, beauty and simplicity of for..

Communication Satellites - 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 transmi..

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. By firing rockets at appropriate heights, th..

Basic Principles of Wireless Radio Communication - Let us now discuss the basic principles of wireless radio communications. We shall mainly concentrate on the principle of amplitude modulation and demodulation. The simplest scheme of wireless communication would be to..

If several satellites are spaced around the same orbit in space, the tracks of the satellites will be different due to Earth's rotation about its own axis. But if, for example, four satellites are placed into different orbits with their ascending modes displaced successively by..
