Abstract

Communication can be broadly classified as analog and digital. These two types only deal with terrestrial networks. But, when we want communication to be achieved with very high efficiency it is very much essential to deal with satellites. Satellite Communication is becoming more advantageous day by day. Almost in all the areas, the importance of satellite communication is being recognized. The role of satellite communication in the disaster management has played an important role these days. This has gained very high popularity because of the failure or delay of the organization to detect the disaster at the right time. Satellite communication is generally useful for information gathering during the disaster [1]. Helicopters are used in the satellite communication technology and this technique is called as Helicopter Satellite Communication System (HSCS). There are few technical issues existing in this system too. Thus to overcome these issues and make it more efficient many schemes have been implemented. One such scheme is hybrid modulation with Automatic Frequency Control (AFC).
