Anello Photonics 的感測器和傳統 MEMS 陀螺儀有什麼不同？

Anello Photonics uses optical interference principles instead of mechanical motion to measure angular velocity, resulting in significantly lower error accumulation over time. The silicon photonic fabrication process also allows the sensor to be miniaturized for UAV-class platforms while maintaining high accuracy and resistance to electromagnetic interference.

這顆感測器在沒有 GPS 的環境下還能導航嗎？

Yes. The sensor is specifically designed for GNSS-denied environments. It provides continuous position, velocity, and attitude data through its IMU without relying on satellite signals, making it effective in locations such as indoor spaces, urban canyons, tunnels, and areas affected by jamming or spoofing.

這項技術適合哪些無人機應用場景？

Key use cases include search-and-rescue operations, infrastructure inspection, autonomous ground robot navigation in mines or tunnels, and UAV missions in electromagnetically congested or signal-obscured urban environments. The sensor can also be fused with GNSS data to enhance overall navigation robustness when satellite signals are available.

Highlights

Anello Photonics is developing a silicon photonic optical gyroscope-based IMU designed to provide accurate navigation for drones and autonomous systems when GNSS signals are unavailable or compromised.
The silicon photonic gyroscope uses optical interference to measure angular velocity, achieving lower error accumulation and a smaller form factor compared to conventional MEMS gyroscopes.
The sensor is immune to GNSS jamming and spoofing, delivering continuous position, velocity, and attitude data even in electromagnetically contested or signal-denied environments.
Target applications include UAV operations in urban canyons and indoor spaces, autonomous ground robots in tunnels and mines, and sensor fusion solutions for autonomous vehicles.
The technology addresses a growing industry need for navigation resilience in complex scenarios such as search-and-rescue, infrastructure inspection, and urban drone missions.

Anello Photonics Silicon Photonic Inertial Sensor: Precision Navigation for Autonomous Systems Without GPS

U.S. startup Anello Photonics is advancing a new generation of silicon photonic inertial navigation sensors engineered for unmanned systems operating in complex, high-interference environments. The technology directly addresses the navigation challenges posed by unstable or unavailable GNSS (Global Navigation Satellite System) signals.

Core Technology: A Breakthrough in Optical Gyroscopes

At the heart of Anello Photonics' product line is an optical gyroscope fabricated using Silicon Photonics technology. Compared with conventional Micro-Electro-Mechanical Systems (MEMS) gyroscopes, the silicon photonic optical gyroscope offers several key advantages:

Higher accuracy: Angular velocity is measured via optical interference principles, resulting in far lower error accumulation than traditional inertial components.
Compact form factor: Silicon photonic integration processes shrink the sensor to a size suitable for UAVs and other space-constrained platforms.
Strong interference immunity: The sensor requires no external satellite signals, maintaining reliable navigation data even in signal-obscured, electromagnetically contested, or GNSS-spoofed environments.

Broad Application Across Autonomous Platforms

The technology is applicable to a wide range of unmanned and autonomous systems, including:

UAVs (Unmanned Aerial Vehicles): Executing missions in urban canyons, indoor spaces, or electromagnetically congested zones.
Autonomous ground robots: Operating in tunnels, mines, and other locations where GNSS signals cannot penetrate.
Autonomous vehicles: Providing high-precision inertial measurement data that can be fused with GNSS for a more robust navigation solution.

The Critical Value of Navigation Resilience

As unmanned systems are deployed in increasingly challenging scenarios, the demand for reliable navigation in GNSS-denied environments has never been greater. Anello Photonics' sensor integrates seamlessly with existing flight control systems, delivering continuous position, velocity, and attitude data through its Inertial Measurement Unit (IMU). Even when satellite signals are lost, the system maintains stable flight or ground operations.

This capability holds significant practical value for search-and-rescue missions, infrastructure inspection, and drone operations in complex urban environments — all scenarios where dependence on GNSS alone is a critical vulnerability.
