Feasibility Study of Data Receiving Station in Korea For CSA UV Space Telescope Project

Abstract

We present a feasibility study of a data receiving station in Korea to be used for a 50 cm UV space telescope proposed by CSA. The feasibility was investigated by examining the spacecraft visibility from four different cities in Korea, based on the orbital characteristics of the proposed spacecraft, i.e. inclination of 28.5 deg and circular orbit altitude of 690km. The satellite can be accessed from Korea about 4 times a day, each pass having the duration of 6 to 9 minutes depending on the elevation mask and the latitude of each site. Provided that the X-Band signal can be retrieved from 10 deg elevation, this study demonstrates that a ground station placed in any of the four cities can be used for a reasonable backup downlink of the science data gathered by the proposed UV space telescope.
