영문 초록

Propagation delay of TTC RF loop back system is measured by using 16 kHz ground space tracking and data network(GSTDN) satellite range measurement method in this study. Amount of propagation delay generated from earth station equipments has to be measured accurately, because the amount has to be compensated for range data. The propagation delay of TTC RF loop back system was 282 ns and its equivalent distance was 84.5 m. These values are almost equal to the measured delay of 272 ns and the equivalent distance of 81.6 m. Therefore the accuracy of distance measurement was demonstrated, and it can be utilized for earth station correction coefficients of measured distance to satellite.
