“…Although digital compass errors cover quadrant errors, etc., the most important error affecting the precision of digital compasses is compass error because the system is composed of both soft magnetic materials and hard magnetic materials [ 23 , 24 ]. Therefore, the error model of the total error of the system is

There are not many high-precision, portable digital compass solutions available right now that can enhance combined navigation systems’ overall functionality. Additionally, there is a dearth of writing about these products. This is why a tunnel magnetoresistance (TMR) sensor-based high-precision portable digital compass system is designed. First, the least-squares method is used to compensate for compass inaccuracy once the ellipsoid fitting method has corrected manufacturing and installation errors in the digital compass system. Second, the digital compass’s direction angle data is utilized to offset the combined navigation system’s mistake. The final objective is to create a high-performing portable TMR digital compass system that will enhance the accuracy and stability of the combined navigation system (abbreviated as CNS). According to the experimental results, the digital compass’s azimuth accuracy was 4.1824° before error compensation and 0.4580° after it was applied. The combined navigation system’s path is now more accurate overall and is closer to the reference route than it was before the digital compass was added. Furthermore, compared to the combined navigation route without the digital compass, the combined navigation route with the digital compass included is more stable while traveling through the tunnel. It is evident that the digital compass system’s design can raise the integrated navigation system’s accuracy and stability. The integrated navigation system’s overall performance may be somewhat enhanced by this approach.

“…The versatility of its features opens great opportunities for creating multiple sensor types, addressing a broad spectrum of requirements. Few examples of physical quantities that can be measured using MEMS-based sensors are pressure [6], acceleration [7], angular rate [8], magnetic field [9], temperature [10], humidity [11], presence of particular gases and/or chemical substances [12], sound intensity [13], and so on. Along with the low cost, the low power consumption, the high integration capabilities, and the great versatility, one of the main advantages of MEMS sensors is the low dimensions and weight, which allow to develop multi-sensor platforms capable of ensuring high performances satisfying multiple requirements.…”

In the modern technological world, there is a notable increase in the demand for precise sensors and sensing platforms in many different application fields. In the context of Industry 4.0, Inertial Measurement Units (IMU) are now playing a central role in positioning estimation and anomaly detection, smart condition monitoring and fault diagnosis tools. Despite this increasing development in recent years, the metrological characterization and sensor performances of inertial platforms still represent a current research gap. Currently, the actual dynamic operating conditions (e.g., temperature, humidity, mechanical stress) endured by the device during its operating life are rarely considered in the literature. However, a thorough sensor characterization needs to consider all external stress sources. Trying to fill this research gap, this study presents the results of a measurement campaign conducted on a triaxial MEMS-based (Micro Electro Mechanical System) IMU performed at different operating temperatures. The dynamic characterization has been carried out emulating the automotive field regarding both movements and operating temperatures. The analysis of the experimental results introduces specific metrics to quantitatively estimate the impact of the temperature dependance on the IMU measuring a repeatable movement.
