The UP-T201 integrates a high-precision optical flow sensor and 15m laser rangefinder in a ruggedized module, designed for drone positioning in GPS-denied environments. Utilizing a 160×120 pixel global shutter CMOS and Class 1 IR laser, it achieves ±0.1m/s velocity measurement accuracy and ±1% ranging resolution. With IP67-rated aluminum housing and -30°C to +70°C operating range, it supports autonomous indoor/outdoor navigation, precision landing, and obstacle avoidance for industrial drones, inspection robots, and AGVs.
