The A12 RTK is a high-precision vehicle terminal supporting multi-system satellite positioning and RTK centimeter-level accuracy. It enables integrated tracking, dispatch, trajectory analysis, and fleet management for vehicles, drones, and vessels. Compatible with JT808 and custom protocols, it connects to our platform, ChaoYue, and national transport systems. Ideal for autonomous driving, precision agriculture, and surveying, it maintains reliable performance in urban, mountainous, and challenging signal environments.
