Product catalog summary

Overview
The EAS502 Multi-Functional Auto-Steering System by ESURVEY is designed to enhance agricultural machinery operations. It integrates a 12-inch high-performance display, EW3 electric steering wheel, and MC6A intelligent control unit, enabling semi-automatic operation to reduce operator fatigue and improve efficiency. The system is suitable for various machinery including tractors, transplanters, sprayers, harvesters, and construction equipment.

Key Features

High Precision: Utilizes MC6A's RTK positioning accuracy (0.8cm+1ppm horizontal) and EW3's precise steering for stable operation.
Durability: Industrial-grade components with wide temperature resistance and IP65/IP67 protection for harsh environments.
Versatile Compatibility: Supports multiple GNSS & PPP modes, including B2B-PPP, HAS-PPP, PPP-AR, PPP-RTK, and SBAS.
Flexible Communication: Integrated 4G, Wi-Fi, and radio modules for stable data transmission and remote control.

System Specifications

Display: 12.1-inch LCD with 1280 x 800 resolution, 750 nits brightness, and capacitive touch screen.
