Communication link between the satellite and earth station is dependent on various propagation and associated losses which are either constant or vary with weather conditions. Role of receiver noise, antenna pointing mechanism, atmospheric effects, slant height, interferences, bit error rate on the link margin are detailed in this article. Various equations for link budget calculation and a comparative table at various frequency bands are shown in this article which is useful for predicting link margin of LEO, GEO and Deep space missions. Tele-command, telemetry and ranging link margin at various frequencies are presented and budget analysis at Ka-band frequency performed.
