Overview
The ANELLO X3 IMU is the world's smallest and lightest 3-Axis high performance optical gyroscope IMU.
The ANELLO X3 IMU leverages three state-of-the-art ANELLO SiPhOG™ (Silicon Photonics Optical Gyroscope) units as low-noise and low-drift optical smart sensors, each containing its own independent 6-Axis redundant IMU sensor.
The ANELLO X3 IMU offers seamless integration with maritime platforms and also with PX4 and ArduPilot — enabling precise, low-drift inertial navigation for autonomous aerial systems. This compatibility allows developers to easily leverage ANELLO's cutting-edge optical gyroscope technology within widely adopted open-source flight stacks, enhancing position accuracy and stability in GPS-denied environments.
The ANELLO X3 IMU's high-performance and plug-and-play integration streamline development, making it an ideal choice for aerial and maritime platforms such as drones, UAVs, VTOLs, UUVs, and ROVs that require dependable navigation in challenging environments.
The ANELLO X3 IMU integrates with PX4 and ArduPilot for aerial applications and also delivers robust performance on maritime platforms
Key Features
ANELLO Drone Navigation Solution for GPS-Denied
ANELLO X3 IMU + ANELLO AI
Drone Solution Today
The moment GPS is lost, the autopilot detects the outage and is forced into a failure mode — hover or land — because it has no independent way to hold its position.
GPS JammingWithout ANELLO
With no trusted navigation source through the jamming, the drone drops out of the mission and is left to land or crash inside the contested area.
GPS JammingANELLO X3 + ANELLO AI Solution
The system automatically detects the loss of GPS and creates a navigation solution, allowing the drone to keep flying straight through the jamming and reach the target.
Continues to TargetWith ANELLO, the flight path continues straight through the jamming zone to the target. Without it, the drone drops out in the middle.
