In short, you can understand that a MEMS gyroscope is included in the north finder, and one of the sensors that make up the north finder is a MEMS gyroscope.
MEMS gyroscope is based on Coriolis effect and adopts MEMS technology. It is the third generation gyro in the history of gyro development. MEMS gyros are used to measure the angular velocity of an object. In recent years, it stands out for its advantages of small size, light weight, low power consumption and low cost.
The North finder is so named because it contains a north finding MEMS gyroscope. The north finder includes a three-axis MEMS gyroscope and a three-axis MEMS accelerometer, which can measure the true north azimuth. Due to the use of MEMS sensors, it also has the advantages of MEMS.
The gyro sensor and the accelerometer sensor form an Inertial Measurement Unit (IMU), and the IMU becomes an inertial system when added to the algorithm. The addition of different algorithms determines the birth of different inertial systems. For example, an algorithm that adds Inertial Navigation System (INS) to an IMU can get an INS, and an algorithm that adds a north finder on top of it can get a north finder. Therefore, MEMS gyroscope is an essential part of the north finder, the north finder is based on the MEMS gyro was developed to create a system.
