Solar drones are reaching new heights. The Horus A model, developed by AeroVironment, opens up both military and civilian possibilities. With its 1.5 kW of solar power, it operates at an altitude of 12.4 miles (20 kilometers). But this is just the beginning of its impressive capabilities.
The Horus A is not just a simple drone, but a true stratospheric platform. Capable of carrying up to 154 pounds (70 kg) of payload, it significantly enhances the HAPS (High-Altitude Platform Station) category. Thanks to this payload, it can accomplish long-duration missions.
During recent trials, the Horus A simultaneously used a synthetic aperture radar and a Mesh Network radio system. Additionally, it demonstrated its ability to operate effectively in adverse atmospheric conditions before landing safely. Its major strength lies in its communications. Equipped with a BLOS satellite radio system and robust avionics, it delivers stable connections and precise positioning. These characteristics allow it to play a key role in both military and civilian operations.
In a military context, the drone excels as a command center for other unmanned systems, such as the Switchblade, a smaller drone used for specific missions. The efficiency of these drone swarms is thus significantly increased. The technology has been validated by the U.S. military, which granted it a special airworthiness certificate for its trials in national airspace. This marks another step towards widespread adoption of these drones.
Beyond its military role, Horus A can also fulfill civilian missions. It could, for instance, enhance telecom connectivity, monitor the environment, or transfer data between mobile operators. Other giants, such as Airbus with its Zephyr, are already exploring these stratospheric frontiers. However, Horus A sets itself apart with its autonomy and communication capabilities.
What is a High-Altitude Platform Station (HAPS)?
HAPS (High-Altitude Platform Stations) are unmanned aerial vehicles that operate in the stratosphere, at about 12.4 miles (20 kilometers) altitude. They are designed to stay aloft for long periods using solar energy, providing services such as monitoring, communication, or reconnaissance.
HAPS occupy a space between satellites and conventional drones. They offer services similar to those of satellites, but with advantages such as lower costs and quicker responsiveness. Additionally, their lower position allows for better coverage and resolution for certain missions.
These platforms are used for both civilian and military missions. They play an important role in telecommunications, environmental observation, and data collection. Their autonomy and versatility make them valuable tools for the future of aeronautics.
