The A12mini is a compact high-precision vehicle terminal supporting multi-system satellite positioning and RTK centimeter-level accuracy. It delivers integrated tracking, dispatch, and fleet management for vehicles, drones, and vessels. Compatible with JT808 and custom protocols, it connects to our platform, ChaoYue, and national freight systems. Ideal for autonomous driving, precision agriculture, and surveying, it maintains reliable performance even in dense urban or mountainous environments with severe signal challenges.
