The ARS690R is a next-generation Integrated GNSS/INS Fusion Navigation System engineered for industries demanding uncompromising precision. By fusing multi-constellation RTK signals, dual-antenna heading correction, and high-frequency inertial data, it delivers continuous centimeter-level accuracy—even in urban canyons, tunnels, or dense foliage.
Precision Engineered for Critical Applications:
- RTK-Enhanced Positioning: Leveraging full-frequency BDS, GPS, Galileo, GLONASS, and QZSS signals, the ARS690R performs real-time kinematic corrections to achieve 0.8 cm horizontal / 1.5 cm vertical accuracy—ideal for autonomous vehicles, precision agriculture, and aerial surveying.
- Dual-Antenna Heading Optimization: Dual GNSS antennas provide 0.05° static heading accuracy, eliminating reliance on magnetic sensors and ensuring reliability in electromagnetic interference (EMI)-heavy environments.
- Seamless Inertial Navigation: When GNSS signals degrade, the system transitions to 200 Hz IMU-driven navigation, aided by vehicle kinematics and proprietary divergence suppression algorithms. With odometry fusion, positional drift is reduced to <0.2% over 1 km—10x tighter than conventional GNSS-only systems.
- Tightly Coupled Fusion Architecture: Deep integration of satellite, inertial, and odometry data through adaptive Kalman filtering ensures sub-decimeter accuracy during rapid acceleration, sharp turns, or signal outages.
Why Choose the ARS690R?
- Robust Redundancy: Dual antennas and multi-source fusion guard against single-point failures.
- High Dynamic Performance: 500 Hz output frequency and CAN FD support meet the latency demands of autonomous driving and robotics.
- Post-Processing Flexibility: Raw data logging enables centimeter-accurate trajectory reconstruction for mapping and forensic analysis.
For drones, AGVs, or industrial machinery operating in GPS-hostile environments, the ARS690R sets the benchmark for always-accurate navigation.
