How Can You Maintain Centimeter-Level Positioning Accuracy in GNSS-Denied Urban Environments?

Our RTK-1612AD-DR module seamlessly bridges GNSS signal gaps with integrated 3-axis accelerometers and gyroscopes, providing continuous dead reckoning when satellite signals are blocked. The sensor fusion technology automatically detects odometer inputs and delivers uninterrupted positioning with pitch, roll, and heading data—critical for autonomous navigation in tunnels and urban canyons. Contact us to see real-world road test demonstrations proving consistent performance where standard GNSS fails.

Designed specifically for automotive applications, the RTK+DR module outputs raw inertial sensor data along with critical vehicle attitude information including pitch, roll, and heading angles—essential for driver behavior analysis and advanced vehicle dynamics monitoring. The module's installation-orientation-free design and automatic calibration function significantly reduce integration complexity and deployment time. Whether you're developing autonomous vehicle systems, fleet management solutions, or advanced driver assistance systems, our RTK+DR modules provide the reliability and precision needed for mission-critical automotive navigation applications with proven performance in real-world road testing environments.

RTK-Enhanced GNSS / Dead Reckoning Hybrid Positioning

Centimeter-Level Accuracy with Continuous Navigation Capability

The module supports RTK (Real-Time Kinematic) positioning with dual-frequency carrier phase measurements, enabling centimeter-level accuracy under RTK correction input. By integrating multi-constellation GNSS observations with high-precision positioning algorithms, the system significantly improves convergence speed, accuracy stability, and real-time navigation performance in demanding environments.

Combined with sensor-fusion navigation, RTK enhances robustness in multipath-rich and partially obstructed scenarios, ensuring reliable high-precision positioning for mission-critical applications.
