Merits and demerits

Merits:

 

  1. No tracking is required by Geostationary Satellites.
  2. Multiple access points are available in Satellite communication.
  3. 24 hour communication can be achieved with the help of satellite.
  4. The signal quality of Satellite communication is higher.
  5. Satellite Communication is used for long distance communication or across oceans.

 

Demerits:

 

  1. The transmitter and receiver used in satellite communication requires high power, most sensitive transmitters and large diameter antenna's.
  2. Satellite communication is disturbed by solar activities and cyclones in the space.
  3. Due to ageing effect the efficiency of Satellite components decreases.
  4. The longer propagation times   (approximately 300 milliseconds) is one of a disadvantage of satellite communication.
  5. The cost for Initial design and launching of the satellite in the orbit results in extremely high.
