LAJU GALAT BIT AKIBAT KESALAHAN PENGARAHAN ANTENA STASIUN BUMI KE SATELIT
Abstract: One problem causing
reduction of energy in satellite communications system is the misalignment of
earth station antenna pointing to satellite. Error in pointing would affect the
quality of information signal to energy bit in earth station. In this research,
error in pointing angle occured only at receiver (Rx) antenna, while the
transmitter (Tx) antennas precisely point to satellite. The research was
conducted towards two satelites, namely TELKOM-1 and TELKOM-2. At first,
measurement was made by directing Tx antenna precisely to satellite, resulting
in an antenna pattern shown by spectrum analyzer. The output from spectrum
analyzers is drawed with the right scale to describe swift of azimuth and
elevation pointing angle towards satellite. Due to drifting from the precise
pointing, it influenced the received link budget indicated by pattern antenna.
This antenna pattern shows reduction of power level received as a result of
pointing misalignment. As a conclusion, the increasing misalignment of pointing
to satellite would affect in the reduction of received signal parameters link
budget of downlink traffic.
