01

Multi-Constellation, Centimeter-Level Accuracy

GC30 delivers highly accurate positioning by tracking all major satellite constellations, including GPS, GLONASS, BeiDou, Galileo, and QZSS. With centimeter-level RTK performance, it provides the precision required for modern agricultural guidance, helping machines operate more accurately and efficiently in the field.

  • Supports all major global satellite constellations
  • Centimeter-level RTK positioning accuracy
  • Improved signal availability in complex environments
  • Reliable guidance for precision farming operations

02

Stable Navigation with Integrated GNSS and INS

With a built-in high-performance IMU, GC30 combines GNSS and INS technology to provide stable roll, pitch, and heading information in real time. Even when satellite signals become weak or temporarily unavailable, the system helps maintain smooth and reliable navigation performance.

  • Built-in IMU for continuous attitude sensing
  • Real-time roll, pitch, and heading output
  • Reliable performance during signal degradation
  • Better stability in dynamic field conditions

03

High Precision Positioning with TAP Service

GC30 supports TAP service, enabling high-precision positioning through L-band satellite correction delivery. Unlike traditional RTK solutions, TAP does not rely on a local base station or CORS network, and no radio or internet link to a correction source is required. This allows manufacturers and users to achieve reliable high-precision performance with a simpler deployment architecture, especially in wide-area agricultural operations.

  • Supports TAP PPP correction service
  • Receives correction data directly via L-band satellite
  • No local base station or CORS dependency
  • No radio or network connection to a correction source required

04

Flexible Integration for OEM Applications

GC30 is designed to support different levels of OEM integration, from high-precision positioning to full navigation and steering control. This flexible architecture allows manufacturers to select the solution level that best fits their machine platform, development plan, and market needs.

  • Four levels of OEM integration
  • From positioning only to full control capability
  • Easier system adaptation for different machine types
  • Scalable solution for diverse product strategies
