FOG vs MEMS in Subsea Navigation: Which One Holds Better? (Part II)
FOG gyroscopes maintain ultra-low drift and long-term stability under GNSS-denied subsea conditions, while MEMS IMUs offer compact, low-power alternatives better suited for short-duration inspections and cost-sensitive platforms.

FOG vs RLG: Evaluating Accuracy, Reliability, and Lifecycle Costs
FOG and RLG are both established gyroscope technologies for defense navigation. But when buyers compare them through the lens of procurement, FOG delivers the optimal balance of performance, reliability, and lifecycle cost for nearly every mission outside of strategic deterrence.
How to Choose a FOG That Integrates, Performs, and Supports You
Selecting the wrong Fiber Optic Gyroscope (FOG) can delay projects and raise costs. Smart buyers look beyond the datasheet-choosing a FOG that integrates smoothly, performs consistently, and comes with guaranteed long-term service and delivery assurance.
Thermal Sensitivity in Fiber Optic Gyroscopes: Design Strategies for Extreme Environments
Thermal sensitivity in fiber optic gyroscopes arises from material expansion, refractive index shifts, and optical source behavior. Advanced strategies-thermal compensation, coil winding optimization, and robust calibration-enable FOGs to sustain accuracy in extreme environments.
Designing with ARW in Mind: Practical Engineering for IMU Selection (Part 2)
Angle Random Walk (ARW) sets the ultimate limit of IMU accuracy. It cannot be removed by software, only reduced through low-noise sensor selection, stable thermal design, vibration isolation, and effective multi-sensor fusion strategies.
Understanding ARW: The Hidden Limit to IMU Accuracy (Part 1)
ARW isn’t a spec—it’s a clock. From the moment your IMU starts, it tells you how fast orientation trust degrades. The lower it is, the longer your system stays right.
10 Design Mistakes Engineers Make When Integrating IMUs
IMU integration errors can destroy navigation reliability. From misalignment and vibration to poor calibration and overreliance on sensor fusion, engineers often repeat the same mistakes. In this guide, we explore the 10 most common mistakes in IMU integration, explain their consequences, and provide expert solutions you can apply in your own projects.
FOG Technology in Spacecraft Attitude Control: Beyond the Limits of MEMS
Fiber Optic Gyroscopes outperform MEMS by delivering long-term stability, radiation resistance, and precision that remains reliable for years. They are indispensable for satellites, constellations, and deep-space probes where accuracy cannot be compromised.
How Multi-Sensor Fusion is Redefining Inertial Navigation Systems
Inertial navigation accuracy is ultimately limited by how well sensor errors are modeled and compensated. From bias drift to random walk, effective mitigation requires a combination of hardware design, calibration routines, and real-time algorithmic correction.
