Custom Gimbal
This system is a high-load, fine-accuracy gimbal. Two X-RST120AK-DE50 rotary stages are used to position the platform to fractions of a degree in both the azimuth and elevation axes. The height and spacing of the gimbal can be customized for each application. A slip ring can be added to eliminate cable tangling during rotation.
