Integrated 10-Axis Sensing System for All-in-One Precise Data Acquisition
The EDC488S integrates a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and high-precision barometer into a single compact module, forming a complete 10-DOF sensing system. It outputs full raw sensor data including angular velocity, linear acceleration, geomagnetic field and barometric altitude without external auxiliary sensors, greatly simplifying hardware wiring and mechanical design of end devices.
Key Precision Specifications (Tested at 25°C, Allan Variance Standard)
3-Axis Gyroscope
Full-scale range ±530°/s, angular random walk down to 0.15°/√h, bias instability of 2°/h, 3dB bandwidth of 450Hz, angular rate noise density of 0.0045 °/sec/√Hz. It accurately captures high dynamic pitch, roll and yaw angular velocities of carriers with maximum dynamic non-linearity controlled within 0.01%FS, eliminating data distortion during high-speed maneuvers.
3-Axis Accelerometer
Bias stability of 70μg and bias instability of 24μg. It reliably outputs linear acceleration and gravitational reference components, distinguishing maneuver overload from static gravity to provide stable vertical reference for attitude solving.
3-Axis Magnetometer
Measurement range ±30 Gauss, supplying geomagnetic north reference to compensate heading drift caused by gyro bias, effectively suppressing yaw divergence during long-duration pure inertial navigation and drastically improving heading accuracy in open-air GNSS-denied environments.
High-Precision Barometer
Operates within 450–1100 mbar with 0.1 mbar resolution. Combined with built-in altitude calculation algorithms, it achieves centimeter-level vertical height measurement, making up for the insufficient vertical precision of GNSS and directly supporting UAV altitude hold, soldier elevation logging and surveying altitude acquisition.
Embedded full-range temperature compensation algorithms cover a wide operating temperature range of -40°C to +85°C. Multi-point temperature drift calibration is implemented during factory production to automatically suppress sensor drift under extreme temperatures and rapid temperature fluctuations, ensuring stable data output in cold plateaus, high-temperature workshops, open vehicle-mounted and other harsh outdoor environments.
Tactical-Grade Fusion Performance Empowers Stabilization & Integrated Navigation
Equipped with self-developed multi-sensor fusion firmware and hardware filter circuits, the EDC488S locally computes carrier quaternions, pitch/roll/yaw attitude angles, velocity and displacement in real time, fully meeting tactical-grade closed-loop control requirements for various high-end equipment.
UAV Flight Control: Vibration resistance up to 3g and shock resistance up to 30g, withstanding rotor vibration, takeoff/landing impact and high-speed flight of mapping, power inspection, agricultural and VTOL UAVs. Its high-quality attitude data supports stable hovering, high-wind maneuvering and centimeter-level fixed altitude positioning, reducing PID parameter tuning difficulty for flight controllers.
Electro-Optical Pods & Industrial Robots: High-frequency data output enables ultra-low latency gimbal image stabilization, robotic arm trajectory tracking and mobile chassis self-balancing, suppressing jitter and drift to boost visual recognition and precision operation accuracy.
GNSS Integrated Navigation Compatibility: Natively compatible with Beidou/GPS dual-mode satellite positioning. When satellite signals are blocked by tunnels, valleys, dense forests or indoor structures, continuous position and velocity estimation is maintained via inertial dead reckoning to avoid positioning interruption and greatly enhance overall system robustness. The high-speed SPI interface supports a maximum data refresh rate of 330Hz, catering to real-time attitude solving for highly dynamic carriers.
The module features a fully sealed metal shielding housing to mitigate electromagnetic interference, delivering jitter-free data under strong electromagnetic conditions such as vehicle-mounted radio and radar systems. Its MTBF exceeds 20,000 hours to satisfy long-term continuous operation requirements of industrial and tactical equipment.
Miniaturized & Low-Power Design Enables Mass Domestic Replacement Across Scenarios
The EDC488S adopts a universal compact form factor with dimensions of 47×44×14 mm and a net weight of merely 50g. It supports wide voltage input of 3.0~5.0V with typical operating power consumption of 1.5W. Its compact size, light weight and low power draw fit perfectly into space-constrained miniature devices. Featuring full pin definition and communication protocol compatibility with the imported ADIS16488, it requires minimal mechanical modification for direct replacement, cutting R&D and hardware transformation costs significantly.
Main Application Fields
Tactical & Industrial UAVs: Mapping, security inspection, agricultural spraying and VTOL fixed-wing drones
Electro-Optical Stabilization Platforms: Airborne pods, vehicle gimbals and individual soldier observation equipment
Intelligent Robotics: Industrial mobile robots, stair-climbing robots and AGVs

Standardized mass production is supported with a fully domestic supply chain to guarantee consistent delivery schedules. It offers prominent cost advantages compared to imported IMUs of equivalent performance, accommodating both small-batch prototype procurement and large-scale project deployment, delivering an optimal domestic solution balancing top-tier performance and project budget for equipment manufacturers.
Conclusion
The EDC488S 10-axis tactical-grade MEMS IMU features five core strengths: pin-to-pin domestic import substitution, integrated 10-DOF sensing, gyro bias instability as low as 2°/h, wide-temperature anti-vibration performance, and lightweight low-power design. It forms a complete link from motion perception and attitude solving to integrated navigation, equipping domestically built intelligent equipment, unmanned systems and special navigation devices with high-precision inertial sensing cores. Whether for aerial vehicles, ground mobile platforms or continuous positioning under signal-obstructed complex environments, the EDC488S outputs stable and accurate multi-dimensional sensor data, breaking reliance on imported high-end inertial sensors and establishing itself as a cost-effective flagship component for domestic attitude control and navigation solutions.
