Description
Summary:Applied to small satellites, some of the implications are increased data throughput when down-linking or up-linking by varying communications parameters and making use of one hardware design and implementation for communicating for many missions, just by updating the software. [...]development time for small satellite communication systems can be reduced in the future. Applying this concept to small satellites can increase data throughput, add the possibility to perform software updates over-the-air and make it possible to reuse the hardware platform for multiple missions with different requirements. [...]development time for future small satellite communication systems can be reduced. [...]the computations in this give just hypothetical estimation and don't represent all the horde useful factors that can and may influence framework execution. THE PROPOSED SYSTEM As mentioned early, this paper aimed to design radio frequency satellite link under noisy environments for 64 QAM modulation system and to solve the major problems during RF satellite system. [...]the Gain of the antenna on the satellite is selected according to the following equations: where nA is the efficiency. [...]this point, the signal is ready to transmit.
