      The full name of MEMS gyroscopes are microelectromechanical system gyroscope. It is a motion sensor that detects and measures the angular movement of objects. It is different from traditional gyroscopes. MEMS gyros use a vibrating structure and the principle is based on the Coriolis force.

      MEMS gyros are used in a wide range of applications, such as oil logging, aerospace and drones, mining, surveying, etc. We will analyze the applications of MEMS gyroscopes in these fields below.

      1.Oil logging

      MEMS gyroscopes are mainly found in oil exploration pipes and provide pointing, steering and guidance in drilling equipment. North-seeking MEMS gyros are often used. Due to the increasing advancement of MEMS technology, more and more companies in this industry choose MEMS gyroscope instead of other gyroscopes such as FOG (Fiber Optic Gyroscope). Another important reason is that many oil exploration pipes are special-shaped, and equipment like FOG cannot be placed in them. MEMS gyros are small in size and can be easily placed in them. Ericco’s MEMS gyros are all of the same size like a fingernail with 11x11x2 mm.

      Compared with other industries, this field has higher temperature requirements for gyroscopes. Most MEMS gyroscopes can reach a maximum temperature of 85 degrees, which requires the assistance of a insulation tube to reach higher temperatures. However, with the advancement of technology, MEMS technology is becoming more and more resistant to high temperatures. ER-MG2-022 is a north-seeking MEMS gyro specially designed for gyro tools, with a maximum temperature of 125 degrees.

      2.Aerospace, drones

      Navigation MEMS gyros are mostly used in this field. Since this field has high accuracy requirements for gyroscopes, most MEMS gyroscopes are navigation grade. It can be used for orientation, navigation, positioning, attitude and motion control of medium and large UAVs and AUVs. It can also be exploited for precise attitude and azimuth maintenance, positioning, and navigation in navigation-grade IMU (Inertial Measurement)/INS (Inertial Navigation System)/AHRS (Attitude Heading Reference System). ER-MG2-300/400 is specially designed for air navigation with 0.03-0.05°deg/hr and 0.01-0.025°/√hr angle random walk.

      3. Mining

      MEMS devices are used for pointing, steering and guidance in advanced mining equipment. The mining industry requires equipment that can work in harsh environments. The vibration resistance and reliability of MEMS gyroscopes are getting better and better, which also provides a good alternative to large and costly FOG and other types of gyroscopes. At the same time, the MEMS gyroscope is also an important part of the north seeker. The north seeker is composed of a gyroscope, an accelerometer and an algorithm. In this field, ER-MG2-50/100 can be used, which is a north-seeking MEMS gyroscope specially designed for ground navigation.

      4. Surveying

      MEMS gyroscopes are mainly used in gyro-theodolite, which are widely used in mining survey, engineering survey and military survey. Since the gyro theodolite mainly achieves high-precision north-seeking, it uses high-performance north-seeking MEMS gyros, such as ER-MG2-50/100, whose accuracy can reach 0.01-0.02°/hr bias instability and 0.0025-0.005°/√ hr angle random walk

      The above are the main application areas of high-precision MEMS gyroscope. I hope you can understand this knowledge through this article. If you are interested in MEMS gyroscopes related products and knowledge, please click on the relevant links below.
