A Satellite Broadcasting Reception System for Ship Using a Two-Axis Antenna Rotating Mechanism

Abstract

For developing a low − cost and simple receptiQn system of satellite _ broadcasting on board， an antenna tracking mechanism using a two −−axis rotator is desired ． On board of the Training Ship ' ' Hokutomaru "

Antenna stabilizing control system using a strapdown 2-axis Azimuth/Elevation method

“…For this reason, it is desirable that small ships be equipped with antenna control equipment, and a lot of antenna equipment using a 2-axis Az/El (Azimuth/Elevation) system that is small and lightweight has been studied instead of the conventional 3-axis and 4-axis antenna control equipment (Busch et al 1997, Chiba et al 1988Loh 1992, Sanada et al 1987, Shiokawa et al 1986Suzuki et al 1997;Yuki et al 1983).…”
