High speed and accuracy control and tracking
Motorized quick deploy antenna is divided into auto-pointing antenna and drive away antnena. The difference is auto-point antenna is controlled by hand holder but drive away antenna is operated by controller. The satellite alignment steps include: coarse alignment, fine alignment, antenna pointing deviation monitoring, automatic satellite tracking, and the automatic satellite tracking process includes fast star tracking and steady star tracking.
