ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper presents the dynamic RF link estimation result for telemetry system of KSLV (Korea
Space Launch Vehicle)-I. In particular, it utilizes the parameters of the instantaneous vehicle
antenna gain pattern in three dimensions, the improvement by polarization diversity combiner at
the ground receiver, and the free space propagation loss. The structural transformation and
discontinuity of ground plane after the separation events of nose fairing, stage, and spacecraft, are
also included in this analysis. As a consequence, the prediction of link variation has been
performed in accordance with ARDP (Antenna Radiation Distribution Plot) and look angle trace
of vehicle. In addition, the optimum position of onboard antennas has been investigated to
provide better RF link margin in the nominal trajectory.
