USF10 Optical Flow Positioning Module for Drones – GPS-Free Indoor Navigation & Stable Hovering Sensor

The USF10 Optical Flow Positioning Module is a high-precision sensor designed to enhance UAV stability and navigation in GPS-denied environments. By detecting real-time pixel displacement of ground textures, it accurately calculates horizontal velocity and position, enabling reliable flight performance even indoors or in confined spaces such as corridors.

This advanced module combines optical flow technology with distance sensing to provide stable hovering and altitude control at low heights. It effectively compensates for the limitations of GPS by delivering accurate visual-inertial positioning data, significantly improving flight stability and operational safety during low-altitude and near-ground missions.

With fast response times, strong ambient light resistance, and compact design, the USF10 module is ideal for drones requiring precise control in complex environments.
