tethered balloons

Tethered balloons are large balloons anchored to the ground with strong cables or tethers, allowing them to stay at fixed heights. They are used for various purposes such as weather observation, surveillance, communication relay, or scientific research. The tether provides stability and control, enabling the balloon to remain in a specific position and altitude. These balloons can be equipped with instruments, cameras, or antennas, and are often used where installing ground-based equipment is difficult or impractical. They offer a mobile, elevated platform for data collection or communication, combining the benefits of altitude with the security of a fixed position.
