ADVANCED AERIAL SURVEILLANCE —
IN THE PALM OF YOUR HAND
Helius is an affordable, ultra-portable, NDAA-compliant Nano UAV that puts advanced aerial surveillance and operational flexibility in the palm of your hand.
Combining aircraft-grade construction with Ascent’s proven coaxial propulsion technology, the pocked-sized Helius can be hand-launched in less than 30 seconds, immediately enhancing real-time situational awareness to operators on the ground.
The rugged, all-weather 249g Helius is purpose-built to ensure soldiers, first responders, and enterprise operators can effortlessly capture the critical insights necessary to keep people, property and critical infrastructure secure.
MORE THAN MEETS THE EYE
Quietly Changing the Game
Engineered to thrive where other drones fail, Helius packs big capabilities into a small, sleek, stealthy package.
Its cylindrical, coaxial design ensures superior performance in high winds and challenging environments, while its ultra-compact form factor and integrated blade storage lets operators carry it easily on a utility belt, tactical vest, cargo pants, or ODU pockets and deploy instantly.
With an undetectable acoustic signature and low-profile operation, best-in-class flight time, mobile device or remote operation capability, and AI-enabled flight powered by advanced onboard edge computing, Helius is a standout for operations that require safety, reliability, and a low probability of detection.
For operators who need a reliable, high-performance small UAV with big capabilities, Helius is easy to operate and field expedient — enabling extended visual range, increasing situational awareness, and reducing personnel exposure to danger. With exceptional capabilities in golden hour and low-light scenarios, Helius empowers operators to confidently meet increasing operational demands in complex, congested environments and tight spaces where larger drones can’t operate.
APPLICATIONS
Although applications for nano drone technology are expanding every day, Helius offers unmatched versatility for a wide range of public safety, security and surveillance, infrastructure inspection, and asset monitoring.

KEY FEATURES AND BENEFITS
Equipped with an integrated Electro Optical 4K, 12.3 MB Ultra Low-Light Sensor that features digital pan, tilt, and zoom, for crystal clear imaging in any environment.
Field swappable, rechargeable batteries minimize operational downtime. The easy-to-read state of charge indicator makes monitoring and replacing batteries effortless.
Like all Ascent products, Helius’ coaxial design and unique cylindrical construction both minimize and protect critical parts from the elements—including rain, dust, and extreme environments. This unique combination not only delivers more capability in a smaller footprint, but it also allows them to operate in weather conditions that would keep other comparable systems on the ground.
