Satellite communication is disturbed by solar activities and cyclones in the space. 1. The baseband signal from the terrestrial network is processed through modulator and then it is converted to uplink frequency [2],[3]. Figure 15.33 is a more detailed functional block diagram of a typical earth station. Multiple access points are available in Satellite communication. A communication satellite is an R.F (Radio Frequency) repeater.

Fig1shows the block diagram of basic VSAT satellite communication system. The use of active phased arrays on board the satellites is considered a viable means of enabling the radiation of high-power multiple beams. Satellite communications systems featuring multiple-beam LEO/MEO satellites have recently been proposed to meet the ever-growing demand for more communication channels. The block diagram of earth station working with three satellites here, the national long distance Telephone network of a 4 countries (A,B,C,D,) through international switching center are connected, consider country “A” the 0/p of the Telephone exchange is applied to the MUX, the multiplexed signal is send to the micro-wave station and from there to the satellite earth station , at the earth station the signal is& multiplexed and directly applied to the modulator stage of earth station where it demodulated with a high frequency signal and transmitted towards the satellite as uplink , in other case the earth station “A” receive three down link signal , the 3 carriers are demodulated and then transmitted toward the micro-wave station and from there international switching center.

Icom IC-910 conventional radio that is primarily used by Amateur Radio Operators for Satellite Communications.....8 3. it would be more useful if losses effected in a optical fibre communication … @�n��� �g�������P����U�����4@=d� Fig. It is very difficult to maintain a communication system 35,800 km out in the space. Although satellite communication system is very expensive the advantage of communicating all over the world at high speed is more important. The transmitted path form an earth station to the satellite is referred to as ‘uplink’ and the transmitted path from the satellite to an earth station as ‘downlink’. The satellite placed in GEO- STATIONARY and placed at an altitude of 22300 miles or 35900 km above the ground level. The block diagram of the power subsystem is shown as: Solar panels generate direct current which is used to operate different subsystems. (i) The necessary components of a communication system are an information source, input transducer, transmitter, communication channel, receiver, and destination.
