Electronically steered beams without using traditional mechanical motors
Without mechanical motors, ESA antennas have no moving parts, avoiding mechanical problems such as wear, failure, and maintenance. This greatly improves the reliability and lifespan of the antenna.
Electronic beam steering is much faster than mechanical motors. This is a significant advantage in multi-satellite tracking, etc. The fast response speed minimizes communication delays and maximizes efficiency.
Electronic control allows for very precise beam steering. This allows for precise control of the directionality and strength of the signal, minimizing interference and improving communication quality.
