Ship Communication System Planning Analysis Using Very Small Aperture Terminal (VSAT) Single Channel Per Carrier (SCPC) With KU-Band Frequency

Abstract

For commercial frequency telecommunication purposes commonly used are C, Ku, Ka-band. C-band is the most popular frequency used in Indonesia, its low frequency is relatively more resistant to rain interference. However, the use of C-band frequency is no longer sufficient for future communication needs. Alternative solution with higher frequency usage than C-band, Ku-band. The advantage of Ku-Band frequency is that with smaller antennas can produce large bandwidth (broadband), the use of Ku-band frequency also avoids interference because it is relatively not used in terrestrial systems. Determination of satellite, concerning the type of satellite, coverage area (footprint), and availability of satellite links (C-Band or Ku-Band). In this thesis the satellites used in data analysis are SES-9 satellites, satellites that are on a 108 ° East orbit with the availability of Ku-Band 81 links. (C / N) Total_inroute and (C / N) Total_outroute for the analyzed links is 11.49 dB and 12.44 dB. This value is greater than the value (C / N) req of 10.22 dB (C / N)> (C / N) req. Ship communication system using VSAT SCPC with Ku-Band frequency can be applied
