Vatomus S850 Multi-mission Industrial Drone

Saolatek is a Vietnamese drone maker founded in Ho Chi Minh City in 2021 by Tran Anh Tuan, with the stated mission of bringing UAV technology closer to businesses and communities. It designs and builds UAV platforms in Vietnam and offers ODM/OEM customization for industrial, rescue, training and research users.

The Vatomus S850 is its flagship multi-mission platform: an 850 mm symmetric quadcopter with a CNC aluminium core and carbon-fibre arms that folds without tools in under five seconds, flies up to 50 minutes and carries up to 2.5 kg. It ships in a Pixhawk 6X edition and an NDAA-aligned Cube Blue H7 edition with RTK GNSS and ADS-B, runs open ROS 2 and PX4 software, and exposes an SDK and API for custom payloads and firmware. Target uses include power-line, solar-farm, telecom and oil and gas inspection.

Vietnam is promoting a low-altitude economy and a domestic UAV industry, while demand for drones in agriculture, industry and security is still largely met by imported products. Utilities, solar operators and telecom companies are adopting drones for routine asset inspection, and buyers increasingly ask for open, customizable and supply-chain-compliant platforms.
