General Description
Starwin 0.7m and 0.55m is a two-way medium profile On The Move Antenna (COTM) with parabolic dish shape to achieve high performance. The antenna rotated in azimuth and elevation which is mounted on a two-axis platform based on optical gyro and inertial navigation system and auto tracking algorithm. Polarization control is provided by rotating elements of the feed chain.
Starwin has extensive expertise in a range of antenna technologies and can offer an antenna design which is best-suited for any given SOTM application, providing the best combination of performance, size and cost.
