High-accuracy inertial navigation system BW-5122

Product Overview​ BW-5122 is a compact, high-precision MEMS intergrated navigation system​independently developed by Ronggan Technology. It integrates a high-performance MEMS IMU​ (Inertial Measurement Unit) and supports external GNSS data input. Utilizing ​multi-source Kalman filter fusion algorithms, it delivers continuous, reliable high-accuracy positioning and navigation information in complex environments. Applications include drones, military training equipment, and stabilization platforms Key Technical Features​ ​MEMS IMU Specifications​ ​Multi-Source Kalman Filter Fusion: Integrates GNSS and IMU data for robust performance in signal-blocked environments (e.g., tunnels, urban canyons) ​Performance in Challenging Environments​ ​Lock Loss Positioning Accuracy: ≤0.2% × D (distance traveled) during GNSS signal loss ​Interfaces: RS-232, CAN/CAN-FD, PPS, and EVENT protocols for flexible system integration. ​Core Functions​ ​Continuous Navigation Output: Combines factory-calibrated IMU data with external GNSS (e.g., odometer and steering inputs) to generate high-frequency position, velocity, and attitude updates. ​Adaptive Data Validation: Self-assesses data reliability through source effectiveness screening and error compensation ​Applications​ ​Drone Navigation: High-precision hovering and trajectory tracking. ​Military Training: Stabilized platform control and mission simulation. ​Autonomous Vehicles: Sub-meter positioning in GNSS-denied zones. ​Industrial Machinery: Precision motion control for heavy equipment. ​Competitive Advantages​ . ​Military-Grade Reliability: Operates in extreme temperatures (-40°C to +85°C) and withstands shock/vibration
