In recent years, with the rapid development of petroleum logging, aerospace, mining, surveying and mapping and other fields, the precision and long-term stability of precision instruments such as MEMS gyroscope has become more and more urgent. Studies have shown that the dimensional instability of materials is one of the main reasons for the poor accuracy and stability of inertial instruments. Dimensional stability is different from thermal expansion or thermal cycling performance, it is the main performance index of precision mechanical parts materials, refers to the ability of parts to maintain their original size and shape in a specific environment. MEMS gyroscope based inertial instrument material There are four main types of inertial instrument component materials, one is metal (such as aluminum and aluminum alloy, stainless steel, copper and copper alloy, titanium alloy, beryllium, gold, etc.) and its composite materials; Second, functional materials (such as iron-nickel soft magnetic alloy, samarium-cobalt hard magnetic alloy, Al-nickel-cobalt hard magnetic alloy, etc.); Third, organic polymers (such as polytetrafluoroethylene, rubber, epoxy resin, etc.); The fourth is inorganic non-metal (such as quartz glass, processable ceramics, etc.), of which the largest amount is metal and its composite materials. In recent years, we have made breakthroughs in high-precision machining manufacturing, low/stress-free assembly technology, but we still find that after the delivery of the instrument, there is a slow drift in accuracy and cannot achieve long-term stability. In fact, after the structural design, parts processing and assembly process is determined, the long-term stability of the instrument accuracy depends on the intrinsic characteristics of the material. The intrinsic properties of the material (such as microscopic defects, second phase, grain size, texture, etc.) directly affect the dimensional stability of the material. In addition, the instrument material will also undergo irreversible dimensional changes under the interaction with the external environment (stress field, temperature field and time, etc.). Figure 1 shows the relationship between the accuracy of the inertial instrument and the service conditions, material microstructure and size change. Taking MEMS gyroscope as an example, its working conditions and storage environment have an impact on the dimensional stability of the material. Even if the MEMS gyroscope has a temperature control system, if the microstructure of the material itself is unstable, there is a metastable second phase, or there is macro/micro residual stress during assembly, the accuracy of the instrument will drift. Figure 1 The relationship among the accuracy of inertial instruments, service conditions,  microstructure and dimensional changes Influencing factors of material change The intrinsic properties of MEMS gyroscope materials mainly include microscopic defects, second phase, grain, texture and internal stress, etc. The external environmental factors mainly interact with the intrinsic properties to cause dimensional changes. 1. Density and morphology of microscopic defects Microscopic defects in metals and alloys include vacancies, dislocations, twins and grain boundaries, etc. Dislocation is the most typical form of microscopic defect, which refers to the defects formed by irregular arrangement of atoms in regularly arranged crystals, such as the absence or increase of half atomic plane of edge dislocation. Due to the dislocation introducing free volume into perfect crystals, the material size changes are caused, as shown in Figure 2. However, in the case of the same number of atoms, the existence of dislocation makes the free volume around the atoms appear, which is reflected in the increase of the alloy size. Figure 2 Schematic of the effect of the microscopic defects density in materials on the dimension of the material 2. Influence of grain and texture on stability The relationship between the strain ε of the metal or alloy under applied stress σ and the grain size d of the material, the density ρ of the movable dislocation, the stress σ0 required for the first dislocation to start, and the shear modulus G of the material is derived: It can be seen from the formula that grain refinement can reduce the strain generated, which is also the guiding direction of microstructure regulation in the stabilization process.In addition, in actual production, when using extruded bars and rolled plates to process precision instrument components, it is also necessary to pay attention to the anisotropy of the material, as shown in Figure 3. Taking 2024Al alloy for mechanical gyro frame as an example, the frame in figure 3(a) generally adopts extruded 2024 aluminum alloy bar. Due to large plastic deformation, the grains will show preferential orientation to form texture, as shown in figure 3(b) and (c), texture refers to the state in which the crystal orientation of the polycrystalline material deviates significantly from random distribution. Figure 3 Microstructure of 2024Al alloy rod for mechanical gyroscope frames Products in Article 3. The influence of environment on the dimensional stability of materials   In general, inertial instruments need to maintain long-term accuracy stability under conditions such as large overload, vibration and shock, and temperature cycling, which puts forward more demanding stabilization requirements for the microstructure and properties of materials. Taking instrument-grade SiC/2024Al composites as an example, long-term dimensional stability is achieved with stabilization process in the manufacturing of inertial instrument structures. The results show that the size change amplitude (~ 1.5×10-4) caused by the constant temperature holding process of SiC/ pure aluminum composite (only the internal stress plays an effect on the size change) is greater than that of the aluminum alloy constant temperature holding process (only the aging precipitation plays an effect on the size change) (~ -0.8×10-4). When the matrix becomes Al alloy, the effect of the internal stress of the composite on the dimensional change will be further amplified, as shown in Figure 4. In addition, under different service environments, the internal stress change trend of the same material is different, and even the opposite size change trend will be shown. For example,SiC/2024Al composites produce compressive stress release at a constant temperature of 190 ° C, and the size increases, while tensile stress release occurs at 500 cold and hot shocks at -196 ~ 190 ° C, and the size decreases. Therefore, when designing and using aluminum matrix composites, it is necessary to fully verify their service temperature load, initial stress state and the type of matrix material. At present, the process design idea based on stress stabilization is to carry out cold and thermal shock covering its service temperature range, release internal stress, form a large number of stable dislocation structures inside the composite material, and promote a large number of secondary precipitation. Figure 4 Dimensional changes in aluminium alloys and composites during constant temperature aging Measures to improve dimensional stability of components 1. Regulation and optimization of micro-defects Selecting new material system is an effective way to control micro-defects. For example, the use of instrument-grade SiC/Al composites,SiC ceramic particles to pin the dislocation in the aluminum matrix, reduce the density of movable dislocation, or change the type of defect in the metal. Taking SiC/Al composites as an example, the research shows that when the average distance between ceramic particles in the composites is reduced to 250 nm, the composite with layer fault can be prepared, and the elastic limit of the composite with layer fault is 50% higher than that of the composite without layer fault, as shown in Figure 5. Figure 5 Two kinds of composite material morphology It should be pointed out that when developing the process route of organizational control, it is also necessary to select the appropriate material system and cold and thermal shock process parameters in combination with the stress conditions and working temperature range of the inertial instrument service environment. In the past, the selection of material system and process parameters relied on experience and a large number of performance data, which resulted in insufficient theoretical basis for process design due to the lack of micro-structure support. In recent years, with the continuous development of analytical testing technology, quantitative or semi-quantitative evaluation of microscopic defect density and morphology can be achieved by means of X-ray diffractometer, scanning electron microscope and transmission electron microscope, which provides technical support for material system optimization and process screening.   2. Regulation of grain and texture   The effect of texture on dimensional stability is the anisotropy that causes the dimensional change. As mentioned earlier, the MEMS gyroscope frame has extremely strict vertical requirements in the axial and radial direction, and the processing error is required to be controlled in the order of microns to avoid causing the centroid deviation of the MEMS gyroscope. For this reason, the 2024Al extruded bar was subjected to deformation heat treatment. Figure 6 shows the metallographic photos of 40% axial compression deformation of the extruded 2024 aluminum alloy and the microstructure photos before and after thermal deformation. Before the deformation heat treatment, it is difficult to calculate the size of the axial grain, but after the deformation heat treatment, the equiaxial degree of the grain at the edge of the bar is 0.98, and the equiaxial degree of the grain is significantly increased. In addition, it can be seen from the figure that the small deformation resistance difference between the axial and radial of the original sample is 111.63MPa, showing strong anisotropy. After deformation heat treatment, the axial and radial small deformation resistance values were 163 MPa and 149 MPa, respectively. Compared with the original sample, the ratio of axial and radial small deformation resistance changed from 2.3 before deformation heat treatment to 1.1, indicating that the anisotropy of the material was better eliminated after deformation heat treatment. Figure 6 Schematic diagram of isotropic treatment, microstructure changes, and performance testing of aluminum alloy rod Therefore, when aluminum alloy bars or plates must be used to process inertial instrument components, it is recommended to increase the deformation heat treatment link, eliminate the texture, obtain isotropic organization, and avoid the anisotropy of deformation. The statistical information of texture can be obtained by EBSD in SEM, TKD in TEM or three-dimensional XRD, and the texture changes can be quantitatively analyzed. Conclusion Based on the urgent need of long-term accuracy stability of inertial instruments, this paper systematically reviews the influence of dimensional stability from the perspective of material science, and puts forward how to improve the long-term accuracy stability of inertial instruments from the intrinsic characteristics of materials.

Key Points Product: High-precision Miniaturized MEMS North Finder Key Features: Components: Inertial Measurement Unit (IMU) with 3-axis MEMS gyroscope and accelerometer, plus power, control, and display circuits. Function: Provides accurate heading autonomously, unaffected by satellites or weather. Applications: Used in mining, oil logging, ships, and tunnels. Inertial Navigation: Measures position, velocity, and acceleration using gyroscopes and accelerometers. Conclusion: The MEMS North Finder is evolving in design, with models like the NF1000 adapting to cylindrical shapes for specialized industries like petroleum logging. As an instrument to measure the Angle between north and true north, North finder can provide accurate orientation and attitude information in the static base environment, and plays an important role in mining, oil logging, ship equipment, tunnel penetration and other fields. Nowadays, all walks of life have higher and higher requirements for the size and accuracy of the north seeker, so the north seeker is more high-precision and miniaturized. Originally, I will start from the basic point of view, focusing on the composition of the north seeking system, so that everyone can understand the north finder more clearly. The basic components of the north seeker The MEMS north finder can provide heading information to the moving body in a fully autonomous manner, working without relying on satellites, not affected by climate, and not requiring complex operations. It not only provides the data output interface for the computer, but also provides a good man-machine interface. The MEMS North finder is mainly composed of the inertial measurement module (IMU) and the line part, and the hardware block diagram is shown in Figure 1. Inertial measurement unit (IMU) is composed of gyroscope and rotary mechanism. The circuit part is mainly composed of four circuit boards, including: power board, control board, power amplifier board and base plate. Table 1 shows the components of the north seeking system. Figure 1 Hardware block diagram of the north seeker Table 1 Components of the North seeker There are two indicators on the panel of the MEMS north finder: north seeker indicator and power supply indicator; Two buttons: north button and power switch; A five-digit seven-segment digital display; A fuse; The device is externally connected with two connectors: a power socket and a communication interface socket.The North finder is composed of inertial measurement units and algorithms, which is the same principle as the inertial navigation system, the difference is that different algorithms form different systems. Therefore, the north seeking system is also an inertial navigation system.Inertial navigation system can measure position information, instantaneous velocity and acceleration and angular velocity through inertial measurement components without interference from external environment, without radiation and in secret, and can continuously provide position, attitude Angle, linear velocity, angular velocity and other parameter information in aviation, aerospace, navigation and military fields.The basic principle of inertial navigation is shown in Figure 2. The coordinate system shown in the figure is oxy, where (x,y) is the instantaneous position. On the platform of an inertial navigation system, the speed Vx, Vy and the instantaneous position x and y are obtained through computer calculation, where the x axis and y axis control the measurement axes of two accelerometers respectively, and the accelerometer is used to measure the acceleration of the two axes. Figure 2 Basic principle of inertial navigation In the inertial navigation system, the Earth’s surface is considered spherical, then the vector position is represented by the longitude and latitude and, if the x and y axes point north and east respectively, the vector position is represented by the longitude and latitude: Where R is the radius of the earth; φ0 – initial latitude of the carrier; λ0 – initial longitude of the carrier;φ – geographical latitude position of the carrier; λ – the geographical longitude position of the carrier;vx – northbound speed; vy – eastbound speed.An inertial measurement unit, also called an inertial navigation unit, consists of an accelerometer and a gyroscope. The inertial navigation system consists of three parts, including the inertial measurement unit, the computer and the display. The acceleration of the aircraft moving in three directions, transverse, longitudinal and vertical, is measured by three accelerometers, and the rotation of the aircraft in three directions, longitudinal and vertical, is measured by the gyroscope with three degrees of freedom. The computer calculates the plane’s speed and position; All kinds of navigation information data are displayed by the display. Conclusion Most of the north finder is a cube shape, but with the increasing demand of various industries, the appearance of the north seeker also changes. For example, the NF1000 is a north seeker designed for petroleum logging, directional drilling and mining, and its shape has made a big breakthrough, evolving from a cube to a cylinder, which can be well adapted to the shape of the probe. Since it is a MEMS north seeker, it contains a three-axis MEMS gyroscope and a three-axis MEMS accelerometer.I hope that through this article you can understand the structure of high-precision miniaturized MEMS north finder, if you are interested in more knowledge of north seeker, please contact us.     NF1000 Inertial Navigation System High Performance Dynamic MEMS North Seeker

Key Points Product: Micro-Magic Inc’s MEMS GNSS/INS, including the I3500 model for mapping applications. Features: Size: Compact and lightweight for easy integration Accuracy: 2.5°/hr bias instability, 0.028°/√hr angular random walk MEMS accelerometer: ±6g range, zero bias instability <30μg GNSS integration for absolute positioning Advantages: Cost-effective, low power consumption, flexible placement, ideal for various applications like UAVs and aircraft, enhancing navigation precision through the fusion of INS and GNSS data. Compared to other INS solutions, a MEMS GNSS/INS has a lower size, weight, power consumption and cost. MEMS-based INS are suitable for most applications, including but not limited to: Marine Surveying, Land Surveying, UGVs, Helicopters, Antenna Targeting, Surveying, Robotics, UAVs. This article highlights five key benefits of using MEMS GNSS/INS. What is MEMS GNSS/INS? MINS/GNSS integrated navigation, refers to the fusion of information from both MINS (MEMS INS) and GNSS (Global Navigation Satellite System). This integration combines the strengths of both systems to complement each other and achieve accurate PVA (Position, Velocity, Attitude) results.The advantages and disadvantages of INS and GNSS are complementary. Therefore, combining the two technologies leverages their strengths to provide continuous, high-bandwidth, long-term, and short-term precise, comprehensive navigation parameters. In INS/GNSS or GNSS/INS integrated navigation systems, GNSS measurements suppress the drift of inertial navigation, while INS smooths the GNSS navigation results and compensates for signal interruptions. Five Reasons for Use MEMS GNSS/INS The manufacturing processes for MEMS devices are highly cost-effective due to mass production techniques used in the semiconductor industry. This results in lower production costs, making MEMS INS more affordable for a wide range of aviation applications. A MEMS GNSS/INS is not as costly as a FOG-based (fibre optic gyroscope) INS Lightweight and small By nature, MEMS are built on a miniature scale and measure in micrometres. This makes a MEMS-based INS an ideal fit for vehicles or machines that need a small payload.Take aviation for example, the compact size of MEMS GNSS/INS devices makes them ideal for use in aircraft where space is at a premium. This allows for easier integration into existing systems and more flexibility in aircraft design, potentially freeing up space for additional equipment or cargo. The lightweight nature of MEMS INS contributes to overall weight reduction in aircraft, which is crucial for enhancing fuel efficiency and performance. Lighter navigation systems allow for better payload capacity and improved aircraft range. Flexible placement The more compact nature of MEMS technology also allows the INS to be mounted in variable positions. The compact and efficient nature of MEMS INS makes them suitable for integration with advanced electronics and automation systems. This adaptability supports the development of more sophisticated management systems and enhances the overall functionality of modern aircraft. Low power consumption MEMS technology has advanced to the point where it can reduce power used, utilising power cycling and low power modes. MEMS GNSS/INS devices are designed to consume less power compared to traditional INS solutions. This reduced power consumption is beneficial for the electrical system, leading to lower operational costs and increased energy efficiency. For battery-powered applications, such as unmanned aerial vehicles (UAVs) or smaller aircraft, the lower power consumption of MEMS INS extends mission durations and operational capabilities, enabling longer flights and reducing the need for frequent recharges. GNSS integration With any kind of inertial navigation system, a MEMS GNSS/INS isn’t able to determine absolute position. By itself, the MEMS INS is able to determine the relative position of the vehicle from a known starting point, accounting for distance travelled and orientation. When a MEMS INS is combined with GNSS (global navigation satellite system) it takes advantage of the satellite technology to accurately determine the absolute position on Earth. With these two navigational technologies working in tandem, the strengths of both enable a high level of accuracy. An Excellent Solution Micro-Magic Inc is at the forefront of inertial navigation technology and has recently introduced three GNSS-aided MEMS INS products with varying levels of accuracy (mapping level, tactical level, and industrial level). Notably, the mapping level MEMS INS I3500 features a 2.5°/hr bias instability and a 0.028°/√hr angular random walk, along with a high-precision MEMS accelerometer with a large range (±6g, zero bias instability <30μg). More importantly, in an integrated navigation system, the INS leverages its high short-term accuracy to provide GNSS with continuous and comprehensive navigation information. Conversely, GNSS helps estimate INS error parameters, such as bias, resulting in more precise observations and reduced INS drift. GNSS offers stable long-term accuracy, provides initial values for position and speed, and corrects accumulated errors in the MEMS INS through filtering. The ER-GNSS/MINS-01 stands out as an excellent solution.
