Paper Abstract

This paper describes the angular error of the tracking antenna system for LEO (Low Earth Orbit) satellite through the alignment experiment. The purpose of this alignment experiment is to reduce the angular error due to the structural alignment and the monopulse null point alignment error. The angular error that can occur during installation on-site, is the key performance parameter of the tracking antenna system. The angular error is analyzed via a simulation and boresight measurement. The simulation is done with formulas to be derived from vector concept for 3-axis movement. The formulas of the structural alignment are verified by comparing the formula result with the field measurement. Also, the angular error due to monopulse null shift is obtained via boresight measurement. The calibration results for both alignments are described.
