“…The schematic of the novel attitude-measurement-while-drilling system is shown in Figure 19 , of which the theoretical error is less than 0.38°. Three real-time estimation experiments of the magnetic heading angle were carried out; the overall estimation error did not exceed 0.35°, and the average estimation error did not exceed 0.3° [ 169 ].…”

Angle measurement is an essential component of precision measurement and serves as a crucial prerequisite for high-end manufacturing. It guides the implementation of precision manufacturing and assembly. The current angle measurement methods mainly focus on multiple axes, high precision, and large measurement ranges. This article introduces the technology of angle measurement from the perspectives of single-axis and multi-axis measurement schemes. Firstly, the single-axis measurement scheme is primarily achieved through optical methods, such as encoder discs that measure energy changes and interferometric phase changes, as well as mechanical, electromagnetic, and inertial angle measurement methods, among which interferometric methods offer the highest accuracy, with high cost, and encoder discs provide the largest measurement range with an ordinary price. Secondly, in the multi-axis measurement scheme, autocollimation instruments, including plane mirrors, gratings, and self-designed targets, are the main options. Although grating encoders can achieve three degrees of freedom in angle measurement with an ordinary price, they are limited in terms of measurement range and sensitivity compared to self-designed targets. Lastly, artificial intelligence assistance precision measurement is increasingly being embraced due to significant advancements in computer performance, making it more convenient to identify the relationship between measured values and detection values. In conclusion, angle measurement plays a crucial role in precision manufacturing, and the evolving and improving technologies provide the manufacturing industry with greater choices. The purpose of this review is to help readers quickly find more suitable technical solutions according to current application requirements, such as single/multiple axes, accuracy level, measuring range, budget, etc.

“…In 2020, Cai, X. et al [ 33 ] used the oblique FOG as the measurement in KF to calibrate the MEMS gyroscope error online, and the simulation experiments proved that the calibration method is true and effective. In 2022, Dai, M. et al [ 34 ] measured the rotational angular rate of downhole drilling tools by FOG and used the cosine fitting method to calibrate the deviation of the magnetometer online, and the calibration error was experimentally verified to be less than 5%. In 2022, Lu, J. et al [ 35 ] proposed a four-position and three-rotation (FPTR) calibration sequence using FOG-IMU as a reference information source to calibrate MEMS-IMUs without a turntable and to calibrate large quantities of MEMS-IMUs.…”

“…In 2012, Wang, X. et al [ 43 ] designed a magnetic inertial altitude-heading reference system (AHRS), consisting of three-axis magnetometers, accelerometers, gyroscopes, and a FOG plus. They measure the three-dimensional trajectory of urban underground pipelines within 200 m in complicated field conditions, where electromagnetic disturbances exist, and the maximum horizontal error is less than 0.4 m. In 2022, Dai, M. et al [ 34 ] designed a small-volume combined magnetic heading measurement scheme of vertical single-axis FOG, tri-axial MEMS accelerometer, and tri-axial magnetometer, which can improve the accuracy of magnetic heading angle measurement in the case of continuous rotation of a large angle. In addition, the combination of GPS and FOG-INS is widely used in many fields because it can provide accurate initial position, but the inability to accurately identify satellite signals in the underground space will lead to information retention or even reception failure, and this phenomenon is more obvious as the drilling depth increases [ 44 , 45 ].…”

Fiber Optic Gyroscope Inertial Navigation System (FOG-INS) is a navigation system using fiber optic gyroscopes and accelerometers, which can offer high-precision position, velocity, and attitude information for carriers. FOG-INS is widely used in aerospace, marine ships, and vehicle navigation. In recent years, it has also played an important role in underground space. For example, in the deep earth, FOG-INS can be used in directional well drilling, which can enhance recovery in resource exploitation. While, in shallow earth, FOG-INS is a high-precision positioning technique that can guide construction in trenchless underground pipelaying. This article extensively reviews the application status and latest progress of FOG-INS in underground space from three aspects—FOG inclinometer, FOG drilling tool attitude measurement while drilling (MWD) unit, and FOG pipe-jacking guidance system. First, measurement principles and product technologies are introduced. Second, the research hot spots are summarized. Finally, the key technical issues and future trends for development are put forward. The findings of this work are useful for further research in the field of FOG-INS in underground space, which not only provides new ideas and directions for scientific research, but also offers guidance for subsequent engineering applications.

This work provides an error compensation strategy based on deep learning to address the temperature error of a fiber optic gyroscope (FOG). The Attention structure was used to improve the Long Short-Term Memory Network (LSTM), and the improved network was utilized to establish the prediction and compensation model of FOG error. From the two perspectives of the learning ability of the neural network and the improvement of FOG performance, this paper selects three indicators: prediction accuracy, mean square error, and FOG bias stability to comprehensively evaluate the performance of the compensation model. Through comparison, the compensation effect is significantly enhanced.
