Characteristics
Fiber optic gyroscopes (FOGs) are revolutionizing precision orientation and navigation across defense, aerospace, industrial, and other sectors. At the core of this breakthrough is the single-axis digital FOG, providing uncompromised accuracy, dynamic range, reliability, and customizable integration.
Sensitive Optical Rotation Sensing
FOGs utilize the phase shift of light through a coiled optical fiber to detect rotation with high sensitivity. As the coil rotates, the effective path length varies between clockwise and counter-clockwise propagation. Advanced fiber materials and optimized coil windings enhance this Sagnac effect, enabling detection of minute angular motion. Digital closed-loop tuning nulls static phase offsets for superb bias stability. The fully-optical sensing principle achieves navigation-grade performance surpassing mechanical gyroscopes.
Calibrated Digital Interface
The FOG’s ultra-precise optical pickup is coupled with advanced digital signal processing (DSP) to output calibrated angular rate measurements. High-resolution analog-digital converters and digital-analog converters ensure fidelity. Temperature compensation, alignment control, filtering, and proprietary DSP algorithms calibrate sensor data for real-world conditions. Data output up to 2000 Hz over serial or analog links enables precise vehicle control. Digital interfaces aid integration while allowing sensor tuning.
Rugged Optical Architecture
FOGs avoid mechanical gyroscope limitations like bearings, pivots, and proof masses. The interferometric optical path resides entirely within the gyroscope, protected from external dynamics, shocks, and vibration. The inert fused-silica fiber optic coil withstands intense mechanical forces and radiation fields. Far exceeding mechanical lifetimes, FOGs offer maintenance-free stability for decades. Their solid-state design enables smaller, lighter navigation packages.
Versatile Application Scope
On land, sea, air, and space platforms, single-axis FOGs deliver ultra-accurate reference data for navigation, pointing, and stabilization. High-performance variants provide strike-grade guidance for missiles and munitions. Low-drift, long-life FOGs also lend themselves to agriculture, surveying, robotics, and industrial instrumentation. Their size, power, and interfaces can be tailored to suit diverse gyroscope requirements.
Unmatched Measurement Stability
FOG sensing stability over time exceeds other gyroscope technologies. Negligible internal friction eliminates mechanical wear-out failure modes. The intrinsic scale factor of the Sagnac effect needs no calibration. Digital closed-loop compensation maintains exceptional bias and angle random walk through extreme mechanical and thermal stresses. This longevity reduces total cost of ownership, with practically no recalibration over service lifetimes measured in decades.
Adaptable Performance Optimization
Onboard DSP enables software-based optimization for particular applications rather than hardware changes. Sensor parameters like loop gain, filtering, and temperature compensation are configured to enhance resolution, bandwidth, dynamic range, or other factors per use case needs. In short, a universal gyro design can be adapted to excel in vastly different rotation sensing challenges through flexible DSP toolsets.
Affordable High-Volume Manufacturing
FOGs once cost thousands, but manufacturing enhancements now enable high-volume production using precision equipment and quality standards unmatched in China. Economies of scale make advanced FOG performance affordable across aerospace, industrial, robotics, and automotive applications. Defense-grade sensors are no longer restricted to exclusive elite platforms. Next-generation stabilization, navigation, and autonomy is viable for cost-conscious customers.
Single-axis digital FOGs are enabling ubiquitous deployment of ultra-precise, adaptable gyroscope technology once confined to exclusive defense and space platforms. Their unmatched combination of performance, longevity, environmental resilience, size, and affordability will continue driving navigation innovations across industries. The future promises ever-more precise aerial, marine, and ground vehicles relying on fiber optic gyroscopes as their core enabler.
How a single-axis digital fiber optic gyroscope works？
The limitation of gyroscopes is that they measure the output along only one axis (x, y, or z) rather than the overall tip movement. For instance, a gyroscope tracking the x-axis generates a 2 Hz output signal but does not produce any output for motion along the y-axis, which may be 1 Hz. Therefore, if y is zero while x is 2Hz, the single axis output could wrongly show zero. Gyroscope outputs can register negatively if either monitored axis shows positive values.
A digital fiber optic gyroscope from a China factory utilizes electronics to translate relative motion across three axes – x, y, and z – into equivalent absolute positioning. This allows mapping the movement onto a sensor with defined dimensions to provide orientation feedback. The motor controller can then toggle between two orientations based on the sensor’s horizontal position – using X.Y or YZ scaling for example – without losing accuracy.
Such China single-axis digital fiber optic gyroscopes are applied where high performance is critical, including precision orientation and stabilization control in spacecraft and satellites. They also serve in military guidance systems for missiles and UAVs, from small remote control toys to full-scale space launch vehicles. One application utilizes the gyroscope for highly accurate linear guidance of large spacecraft like Manned Orbiting Astronaut vehicles. Another leverages the single axis stability and accuracy over three axes with sensors. Yet another exploits long life operation with limited temperature sensitivity and high resolution without power supply changes when combining sensors. And one variant uses focused/deflected light to enable precise positioning at very low cost by eliminating moving parts.
