Abstract
This paper will discuss the alignment techniques and measurement results of geostationary satellite communication antennas for correct antenna pointing and also the fixtures. To get the best performance in terms of antenna pointing and fixtures, zero G condition have been simulated and laser tracker and theodolite system have been applied. As a result, alignment stability was verified within the tolerance, ${\pm}\;0.25mm$ and ${\pm}\;0.013^{\circ}$ and finally Ka-band deployable antenna alignment has been accomplished within the tolerance, ${\pm}\;0.5mm$ and ${\pm}\;0.015^{\circ}$.
