Alphabet-owned Loon plans to bring internet balloons to Kenya

The video explains Loons Internet, a project using tennis court-sized polyethylene balloons filled with helium and powered by solar panels. These balloons fly in the stratosphere, about 20 kilometers above sea level, and are programmed to navigate using wind channels. They predict speed and direction to maneuver effectively. The balloons are equipped with antennas to receive wireless internet signals from local telecom partners and relay them to other balloons, providing internet connectivity across regions.

How do the balloons navigate in the stratosphere?

What is the function of the antennas on the balloons?
