Introduction and features of MEMS north seeker

North Seeker is a direction indicating device based on inertial technology. Inertial technology is a comprehensive technology integrating classical mechanics and physics, which can control trajectory and movement posture. Its emergence promotes the development of independent north-seeking and high-precision direction of the north-seeking system. The north finder based on the gyroscope makes use of this inertial technology and occupies an important position in the application of inertial technology. It can get rid of the limitations of natural conditions, quickly achieve autonomous high-precision positioning, and work continuously for a long time. These advantages determine North-seeking equipment has broad development space.

Obtaining correct azimuth information is an important key to inertial technology. Gyro north-finding technology is an orientation technology that can independently measure true north without relying on other external conditions. Except for high latitudes, it is not affected by any magnetic field, temperature, and climate. The impact can be directed globally and around the clock.

The traditional north-finding method cannot meet the current demand for high-precision measurement and is being replaced due to its low accuracy. The size of instruments and equipment has changed from large to compact and integrated. During the mining process, the geographical environment around the mine site, magnetic field changes, and temperature changes will interfere with traditional north-seeking equipment and affect the accuracy of north-seeking equipment. For traditional north-seeking equipment, overcoming these interference factors is the key.

The MEMS north seeker is generally called the micro electric mechanical system gyro north finder. It is a gyro north seeking device based on MEMS technology. Due to its small size, light weight, low energy consumption and low cost, it can be produced in large quantities. It has features that other traditional north seekers do not have. It is widely used in drones, aerospace, automotive industry, mining, oil exploration and other fields. With the development of science and technology, people have higher and higher requirements for the north-seeking accuracy of north-finding instruments. Its performance continues to improve and its cost continues to decrease. It has broad development prospects in both military and civilian fields.

Features of MEMS gyro north seeker:

Traditional gyroscopic north seekers are large and expensive. With the development of technology, MEMS gyro north seekers have the characteristics of small size, low energy consumption and low cost that fiber optic north finders do not have. They are now very popular in both military and civilian fields.

Three-axis MEMS gyroscope and three-axis MEMS accelerometer serve as its core components. The three-axis MEMS gyroscope measures the angular velocity of the carrier in three axes, and the three-axis MEMS accelerometer measures the linear velocity component of the carrier. After a series of algorithms, the position parameters of the carrier are obtained.

Another feature is full temperature compensation. During the drilling and mining process, temperature is an important indicator of well logging. It also affects the stability of mining equipment and ensures the safety of mining operations. Therefore, the feature of full temperature compensation helps the north-seeking equipment reduce data errors caused by temperature during operation and improve data accuracy.

It can withstand harsh monitoring environments. The internal structure of the MEMS north finder is simple, unlike traditional mechanical north finder equipment. It has few built-in accessories, is impact resistant, is not affected by magnetic fields, and has a long life. It is very suitable for engineering needs in harsh survey environments.

The above are the basic characteristics of MEMS north seekers. If you are interested in MEMS series products, you are welcome to take a look at our smallest size MEMS north seeker.
