What is a fiber optic gyro, and how does it work?
Article Abstract: The fiber optic gyro (FOG) is a solid-state sensor that measures the rotation of the Earth in terms of degrees, minutes, and seconds. This technology is fundamental to modern inertial navigation systems, aerospace guidance, autonomous vehicles, and precision industrial motion control. Unlike mechanical gyroscopes or micro-electromechanical systems (MEMS), fiber optic gyros are built […]
What is the difference between MEMS and piezo accelerometers?
Abstract： Accelerometers are the fundamental components of many modern industrial, automotive, aerospace, consumer electronics, and condition monitoring systems. Among the most commonly embraced technologies are accelerometers based on the principle of magnets, the motion of which is converted into electrical signals, and piezoelectric accelerometers, which utilize a different physical principle. MEMS accelerometers have the greatest […]
What is the difference between a fiber optic gyro and a ring laser gyro?
Article Abstract: Fiber optic gyros (FOGs) and ring laser gyros (RLGs) are both popular high-precision sensors for inertial rotation in modern navigators. Studies have demonstrated that both technologies utilize the Sagnac effect; however, they are fundamentally different in regards to optical design, signal generation, performance characteristics, and application potential. This article provides a comprehensive, industry-oriented […]
What Is an Inclinometer Used For: An In-Depth Guide
Article Summary: Inclinometers are specialized instruments that are intended to measure the degree to which a surface is tilted, slanted, or inclined relative to gravity. Inclinometers have a significant impact on civil engineering, geotechnical surveying, automotive technology, and industrial automation. They provide a dependable means of obtaining data about the angle of inclination. Meanwhile, the […]
What Is a Determination System in Measurement?
A determination system in measurement is a functional layer that interprets measurement data and produces clear decisions, states, or classifications based on defined criteria. It connects raw measurement results with control actions by applying consistent rules, thresholds, or models, enabling automated, reliable, and traceable decision-making in modern measurement and measurement-and-control systems.
Why Solid State Gyros Are Replacing Traditional Gyro Technologies
Solid state gyros have become a cornerstone of modern motion sensing and navigation systems. As industries move toward higher reliability, lower maintenance, and greater integration with digital systems, traditional gyro technologies are increasingly giving way to solid state alternatives. This shift is not driven by a single advantage, but by a combination of performance stability, […]
What Is a MEMS IMU?
In modern navigation and motion sensing technology, IMU and MEMS are two closely connected concepts that together form the foundation of today’s inertial sensing revolution. Although they represent different technical levels — one is a system for motion measurement, and the other is a micro-manufacturing technology platform — the fusion of these two has reshaped the landscape of sensing technology.
Digital Fiber Optic Gyroscopes: The Strategic Core of High-Precision Navigation Systems
In the realm of autonomous navigation and precision guidance, Digital Fiber Optic Gyroscopes (DFOGs) are evolving from an advanced technology into a critical strategic component, thanks to their revolutionary performance. They are not merely sensors but the core enablers of system reliability, efficiency, and autonomy in extreme environments.
The Invisible Sensor: How Inertial Sensors Quietly Drive Our World
When you pick up your phone, drive your car, or watch a drone fly smoothly through the air, you might not realize that a crucial technology is silently operating—the inertial sensor. Hidden within the device, it acts like a keen “motion sensor,” capturing in real time every change in acceleration, every subtle rotation, and every adjustment in attitude, allowing the machine to “sense” its own state and thus react precisely.
What Is a Tactical Grade IMU?
At the heart of modern navigation and motion tracking technologies lies a crucial component called an Inertial Measurement Unit (IMU). From smartphone screen rotation to autonomous spacecraft navigation, IMUs provide motion sensing and positioning capabilities by measuring linear acceleration, angular velocity, and the direction of the Earth’s magnetic field. However, different application scenarios have vastly different requirements for accuracy, stability, and environmental adaptability. Therefore, IMUs are classified into four distinct grades: consumer grade, industrial grade, tactical grade, and navigation grade. This article will delve into the technical characteristics and application scenarios of these four types of IMUs.
