Sigma D4G FOG IMU

Sigma D4G FOG IMU – High-Precision Navigation Module for UAV and Robotics Applications

The Sigma D4G FOG IMU is a cutting-edge flight controller accessory that delivers unmatched accuracy in navigation and inertial measurement for UAVs, autonomous vehicles, and robotics systems. Engineered with a fiber optic gyroscope (FOG) and enhanced GNSS RTK positioning, this module ensures rock-solid stability, real-time responsiveness, and centimeter-level accuracy even in challenging environments.

Key Features:

• Ultra-precise orientation: 0.05° roll/lean accuracy, 0.1° absolute course with 2m baseline

• High-accuracy positioning: Single-point: 1.5m H / 2.0m V | RTK: 0.8cm + 1ppm H / 1.5cm + 1ppm V

• Reliable velocity tracking: Up to 0.03 m/s accuracy with RTK

• Rapid GNSS acquisition: 1s warm start, with 20ns timed accuracy

• Robust IMU output: Data rates up to 1000Hz for high-frequency control loops

Designed with versatile communication ports (RS232, RS422, CAN, USB) and multi-protocol support (FDILink, NMEA 0183/2000, RTCM, Simrad), the Sigma D4G ensures seamless integration with modern autopilot systems. Its rugged IP5X-rated casing and wide operating temperature range (-40°C to 85°C) make it a reliable choice for both aerial and ground operations.

Compact and power-efficient, the D4G runs on 8–48V input and consumes just 2.5W, making it ideal for mission-critical systems where performance and efficiency matter.

Optimize your UAV navigation performance with the Sigma D4G – a professional-grade IMU built for precision, durability, and fast data fusion.
