high-precision navigation

Discover the top 5 advantages of MEMS GNSS/INS technology, including cost efficiency, lightweight design, and high accuracy. Ideal for drones, aviation, and surveying.   In modern navigation technology, MEMS GNSS/INS (Micro-Electro-Mechanical System Global Navigation Satellite System/Inertial Navigation System) has gradually become the preferred solution in numerous application fields due to its unique advantages. Whether it is marine surveying, land measurement, or navigation for unmanned aerial vehicles (UAVs), robots, or helicopters, MEMS GNSS/INS can provide outstanding performance. Today, let's talk about its five core advantages.   一、What is MEMS GNSS/INS? MEMS GNSS/INS is a technology that integrates MEMS inertial navigation system (MINS) with global navigation satellite system (GNSS). By combining the advantages of both, it can provide high-precision position (Position), velocity (Velocity) and attitude (Attitude) information, which is abbreviated as PVA. GNSS: Provides absolute position information through satellite signals, but is susceptible to interference or interruption of the signals. INS: Based on inertial sensors, it can continuously output motion data, but there is a problem of error accumulation.   The complementarity of the two enables the integrated system to not only suppress the drift of inertial navigation but also make up for the instability of GNSS signals, thereby achieving high-precision navigation over both short-term and long-term periods.   二、Analysis of Five Major Advantages 1. High Cost Efficiency The manufacturing of MEMS devices adopts the large-scale production technology of the semiconductor industry, which significantly reduces the production cost. Compared with traditional inertial navigation systems such as fiber optic gyroscopes (FOG), the price of MEMS GNSS/INS is more affordable and suitable for a wider range of applications in aviation and other fields.   2. Lightweight and Portable The core feature of MEMS technology is miniaturization, with its size typically measured in micrometers. This compact size makes it an ideal choice for devices with limited space, such as drones or small aircraft. The lightweight design not only reduces the overall load but also enhances fuel efficiency and flight performance.   3. Flexible Installation The compactness of MEMS GNSS/INS enables it to be adapted to various installation positions, whether fixed on the wing, fuselage, or other confined spaces, and can be easily integrated. This flexibility provides more possibilities for the design of modern avionics systems and automation equipment.   4. Low-power Design The advancement of MEMS technology has significantly reduced power consumption. Through the optimization of power supply cycles and low-power modes, the energy consumption of MEMS GNSS/INS is much lower than that of traditional inertial navigation systems. For devices powered by batteries (such as drones), this means longer mission times and fewer charging requirements, significantly enhancing operational efficiency.   5. GNSS integration enhances accuracy Simple MEMS INS can only calculate the motion trajectory based on relative positions, while GNSS can provide absolute positioning. The combination of the two not only compensates for each other's shortcomings but also corrects the accumulated errors of MEMS INS through filtering algorithms, achieving higher-precision navigation.   三、Outstanding Solution: Micro-Magic MEMS INS As a leader in inertial navigation technology, Micro-Magic has launched three GNSS-assisted MEMS INS products with different levels of accuracy, covering requirements for surveying, tactical, and industrial applications. Among them, the surveying-grade product IF3500 stands out particularly: Zero bias stability: 0.06°/hr Accuracy of heave measurement: 5cm or 1% High-precision MEMS accelerometer, with a range of ±10g, zero bias instability < 30µg   This product achieves a seamless integration of GNSS and INS, not only providing short-term high-precision navigation information, but also correcting long-term errors using GNSS. It is an ideal choice for various high-precision applications.   四、Conclusion MEMS GNSS/INS, with its features of low cost, lightweight, flexible installation, low power consumption and high accuracy, is redefining modern navigation technology. It can bring significant value enhancement to users in fields such as aviation, surveying, and automation. If you are looking for an efficient and reliable navigation solution, MEMS GNSS/INS is undoubtedly worth considering! IF3600 Whatever you needs, Micro-Magic is at your side.

Discover the NF1000 MEMS magnetic north sensor, a compact, high-precision tool for coal mining drilling. Enhance accuracy, reduce costs, and resist interference in harsh environments. Introduction: The Need for Precise Navigation in Coal Mining Operations Coal, as one of the important basic energy sources, its extraction efficiency and safety become particularly crucial as the depth and difficulty of the mine increase. In the complex underground environment, the traditional compass is prone to be interfered by electromagnetic fields, causing deviation in the drilling direction and thereby affecting the overall operation efficiency. At this time, a high-precision north-seeking instrument becomes a valuable assistant for engineers. Today, we will focus on introducing a MEMS magnetic north-seeking instrument specifically designed for oil and coal mining - the NF1000. It is not only compact and portable, but also capable of providing accurate direction guidance in harsh environments.   The core advantages of the NF1000 MEMS magnetic north-seeking instrument 1.Compact and lightweight, suitable for narrow spaces The NF1000 adopts a cylindrical design, with dimensions of 85mm × Ø31.8mm and a weight of no more than 400g. This compact shape enables it to be easily inserted into the probe tube, making it highly suitable for the limited construction space in underground environments. Moreover, its Attitude tracking measurement accuracy is 0.1°(1σ), capable of meeting the requirements of complex terrains.   2. High-precision orientation, ensuring drilling trajectory This compass device is equipped with high-performance three-axis MEMS gyroscopes and accelerometers, with the maximum orientation accuracy reaching 1°secψ (1σ) 。 By providing real-time direction information, it helps engineers precisely control the drill bit trajectory, ensuring that the drilling operation proceeds strictly in the predetermined direction, thereby avoiding resource waste and safety risks caused by deviations.   3. Low cost and high performance, MEMS technology empowerment Compared with traditional navigation equipment, the NF1000 adopts MEMS technology, maintaining high performance while significantly reducing costs. This high-performance-to-cost ratio feature enables more enterprises to enjoy the convenience and safety brought by high-precision navigation technology.   4.
