Ka-Band Rain Attenuation Modeling Project

Objectives

  • Focusing on signal attenuation for Ka-band communication satellite

  • To establish a database from collected Ka-band beacon signals and related meteorological data

  • To develop a rain attenuation model that links the rain process and its atmospheric effects

  • To develop practical site-switching algorithm for site diversity for continuity and reliability of communication link

Benefits and Achievements

 A Regional Ka-Band Rain Attenuation Model has been developed

  • The proposed Model presented at the IAC2017, Australia

  • The methodology for Effective Rain Rate Conversion to be published in ITU Journals

  •  The proposed Model will be addressed to ITU Working Group for possibly adoption

A Site-Switching Algorithm for site diversity has been developed

 The Model and Algorithm have been shared among APSCO Member States for practical applications in their countries
