PRODUCT DESCRIPTON
The ERDI LASER® SPD1200S2G is an advanced 905nm laser rangefinder module with integrated gyroscope, designed for both distance measurement and spatial orientation sensing. It provides precise ranging from 0.2 m to 1200 m, with extended nighttime capability up to 1500 m, while simultaneously delivering attitude data (roll, pitch, yaw) for enhanced spatial awareness. By combining laser ranging with orientation sensing, the module enables accurate 3D positioning and dynamic measurement, making it ideal for UAV mapping, tracking, and advanced electro-optical systems.
Key Advantages
- Integrated Gyroscope System: Built-in orientation sensing enables real-time measurement of roll, pitch, and yaw angles.
- Spatial Measurement Capability: Supports distance calculation between spatial points, enabling 3D positioning applications.
- High-Sensitivity Detection: Large receiving aperture improves signal acquisition and measurement stability.
- High Accuracy Performance: ±0.3 m short-range accuracy with optimized long-distance compensation.
- Real-Time Measurement: 4–15 Hz adaptive frequency supports dynamic tracking and moving target measurement.
- System Integration Efficiency: Combines distance and orientation sensing in one compact module, reducing system complexity.
