Anello X3- Worlds Smallest & Lightest 3-Axis Optical Gyroscope IMU (SiPhOG Technology)

The ANELLO X3 is the world's smallest and lightest 3-Axis Optical Gyroscope Inertial Measurement Unit (IMU), designed for next-generation autonomous systems and navigation in GPS-denied environments. Built on ANELLO's patented SiPhOG™ (Silicon Photonics Optical Gyroscope) technology, this compact IMU delivers ultra-low drift, high-reliability angular rate measurements trusted in aerospace, defense, robotics, UAVs, and industrial automation. Unlike traditional bulky optical gyroscopes, the ANELLO X3 integrates three independent SiPhOG™ units, each paired with a redundant 6-Axis MEMS IMU, providing 21 total sensor channels for maximum accuracy, redundancy, and fault detection. This unique hybrid design ensures low-noise, low-drift performance even under harsh conditions such as shock, vibration, and thermal gradients. Key highlights include: High Precision Gyroscope Performance: Bias instability < 0.5°/hr, Angular Random Walk < 0.05°/√hr, and scale factor error < 0.1%. Redundant MEMS IMUs: Triple 6-Axis MEMS IMUs (18 axes total) with bias instability of 20µg and 1.5°/hr, ensuring robust fault tolerance. Flexible Data Output: High-speed UART or RS-422 interface supporting up to 921600 baud and 200Hz sample rate. Time Synchronization: PPS/Sync input for precise alignment with external GNSS/GPS clocks. Safety & Reliability: Built-in-Test (BIT) diagnostics, ASIL-B ready microcontrollers, and ASIL-D rated master CPU for functional safety. Rugged Design: IP54 sealing, shock resistance up to 20g, vibration endurance of 4gRMS, and operating temperature range of -10°C to +50°C. Compact & Lightweight: Only 51mm × 51mm × 44.5mm in size and <182g in weight, making it ideal for space-constrained platforms. Long Life: MTBF > 50,000 hours, ensuring dependable operation in mission-critical applications. The ANELLO X3 is a plug-and-play solution requiring only a regulated 4–24 VDC power supply and consuming less than 5W. With its photonic integrated circuit (PIC) technology, it eliminates the need for discrete optical components, reducing size, weight, and cost while maintaining unmatched accuracy. Applications: Autonomous Vehicles & UAVs Defense & Aerospace Navigation Robotics & Industrial Automation Marine & Subsurface Navigation Surveying & Mapping in GPS-denied zones With its state-of-the-art SiPhOG™ technology, the ANELLO X3 sets a new benchmark for miniaturized, high-performance optical gyroscopes, delivering precision, reliability, and scalability for the most demanding navigation and positioning applications.
