Abstract

The National Remote Sensing Centre (NRSC) has established its ground station named Antarctica Ground Station for Earth Observation Satellites (AGEOS) at Bharati station located at Larsemann hills area of Antarctica for the tracking and data acquisition from polar orbiting satellites. A communication link through a geostationary satellite in C-band is being used for transferring data to the mainland. There is a need to enhance the data rate in the near future considering the huge volume of data being acquired at AGEOS. A satellite link operating at Ka-band is proposed for accommodating the bandwidth requirements. It is necessary to estimate the worst case atmospheric attenuation at Ka-band over Larsemann hills area for calculating the link margins required. The India Meteorological Department (IMD) has setup a wide range of meteorological instruments at Bharati station and the local data collected for the years 2020, 2021 and 2022 are used in this study. The link is assumed to operate at a frequency of 20 GHz with linear polarization. An exceedance probability of 0.1% is used to arrive at the annual statistics of the attenuation. Recommendations by the International Telecommunication Union (ITU) are followed and the estimation is carried out using MATLAB. An estimated total atmospheric attenuation of 2.28 dB is obtained. The results are used further for carrying out link budgeting for a Ka-band satellite communication link between Bharati station and India.

对在南极洲拉尔斯曼丘陵地区运行的 Ka 波段地球空间无线电链路的大气衰减进行估算

国家遥感中心（NRSC）在位于南极洲拉尔斯曼丘陵地区的巴拉蒂站建立了名为南极洲地球观测卫星地面站（AGEOS）的地面站，用于跟踪极地轨道卫星并获取数据。通过 C 波段地球静止卫星的通信链路将数据传输到大陆。考虑到 AGEOS 获取的数据量巨大，在不久的将来有必要提高数据传输速率。为满足带宽要求，建议使用 Ka 波段的卫星链路。为计算所需的链路余量，有必要估算拉尔斯曼丘陵地区 Ka 波段最坏情况下的大气衰减。印度气象局（IMD）在 Bharati 站安装了多种气象仪器，本研究采用了 2020、2021 和 2022 年收集的本地数据。假设链路工作频率为 20 千兆赫，线性极化。采用 0.1% 的超标概率得出衰减的年度统计数据。研究遵循国际电信联盟（ITU）的建议，并使用 MATLAB 进行估算。估计得出的大气总衰减为 2.28 dB。这些结果将进一步用于巴拉蒂站和印度之间 Ka 波段卫星通信链路的链路预算。

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
