Up to 59-Min Endurance | Dual EO + Thermal | GPS-Denied Capability | Low Acoustic Signature

Vantage Robotics’ Vesper is a military-grade micro UAS designed for ISR, close-area surveillance and aerial reconnaissance. Its modular propulsion, payload and battery options support a range of missions, combining low-light imaging, secure communications and portability. The aircraft packs into an IP68 field case with a combined weight of just 1 kg and can be deployed within 90 seconds.

Extended endurance for sustained operations. With the Recon Rotor Assembly, Vesper delivers up to 59 minutes of forward flight, 54 minutes of hovering and a flight distance of up to 45 km. Maximum flight endurance is measured at 7 m/s forward flight. Magnetically attached batteries can be swapped in seconds between sorties, while an optional tether kit supports continuous flight.

Low-light and thermal imaging. Vesper’s field-swappable, three-axis stabilised gimbal combines dual 4K EO cameras with a choice of 320 × 240 or 640 × 480 LWIR thermal imagers. The wide-angle EO camera offers low-light performance down to 8 mLux with the colour payload or 2 mLux with the optional black-and-white payload. The imaging system provides 48× combined optical and digital zoom, electronic image stabilisation and 1080p or 4K video recording at 30 fps. Black-and-white payloads are available on request in custom bundles.

Mission-configurable modularity. Two interchangeable rotor assemblies support different operating environments. The Shrouded Rotor Assembly is designed for indoor flight, confined spaces, subterranean operations and flight near personnel, offering up to 30 minutes of hovering. The Recon Rotor Assembly prioritises endurance, stealth and speed, delivering a maximum speed of 18 m/s / 40 mph / 35 kt. Vesper supports operation in 35 kt sustained winds and 50 kt gusts, with an acoustic signature below 37 dBA at 25 m. Its field-replaceable gimbal can be swapped in minutes.

GPS-denied capability. Vesper combines redundant GNSS, visual-inertial odometry and optical flow for position control. Specified GPS-denied flight altitudes vary by configuration: 30 m for the Public Safety, Public Safety Pro and ISR bundles, and 50 m for ISR Pro. Autonomous functions include position hold, missions, return-to-home and return-to-pilot, orbit, tracking and precision landing.

Software and controller compatibility. Vesper supports RAS-A, MAVLink, QGroundControl, ATAK, DroneSense and Cape. It is compatible with the Vantage Vision2 GCS and other RAS-A-compliant controllers.

Security and compliance. Vesper features AES-256 encryption on all communications and bonded construction to prevent tampering. Remote ID is optionally available. The system is Blue UAS cleared, NDAA compliant, and designed, sourced and built in the United States.
