Fotokite Sigma: Tether-Powered Aerial System for Continuous Operation

The Fotokite Sigma operates entirely on tether-supplied power, a design choice that supports continuous uptime—particularly important for public safety and defense applications. Unlike other drones, it relies solely on the tether for flight power, with onboard batteries used only as a safety backup, not for standard operation.

This approach eliminates the need for battery recharging or replacement, providing a practical advantage over other tethered systems marketed as “persistent.” The result is a system that offers dependable, uninterrupted flight and enhanced operational autonomy.
