What are high-flying drones and how do they differ from regular drones?
High-flying drones are unmanned aerial vehicles (UAVs) that are capable of flying at extremely high altitudes, typically above 10,000 feet. These drones are designed to operate in the stratosphere, which is the layer of the atmosphere that extends from about 12 to 31 miles above the Earth’s surface. Regular drones, on the other hand, are typically designed to fly at much lower altitudes, usually below 500 feet.
The main difference between high-flying drones and regular drones is their design and construction. High-flying drones are built to withstand the extreme conditions of the stratosphere, including thin air, low temperatures, and intense radiation. They are also equipped with specialized sensors and payloads that allow them to collect data and conduct missions in this environment. Regular drones, on the other hand, are designed for more conventional uses such as aerial photography, surveillance, and recreational flying.
What are the potential applications of high-flying drones?
High-flying drones have a wide range of potential applications across various industries.
