A high-precision positioning device based on the time difference of arrival of radio signals for positioning. The device measures the time difference between the arrival of the target signal at multiple receiving stations, and combines the known location information of the receiving stations to calculate the position coordinates of the target. Through device networking, precise positioning and trajectory tracking of drones can be achieved.

◇ Suitable for city level distributed drone positioning and trajectory tracking.
◇ Large coverage area, a single system can cover several square kilometers.
◇ Capable of resolving national standard Remote IDs and mainstream drone protocols.
◇ Capable of recognizing and locating multiple targets
