Definition Of Inertial Navigation System And Micro-Custom Navigation System

The inertial navigation system (INS, Inertial Navigation System) uses the gyro and accelerometer as the navigation parameter solving system of the sensitive device. The system establishes the navigation coordinate system according to the output of the gyro, and calculates the navigation vector carrier according to the output of the accelerometer. The speed and position in the navigation coordinate system, while the inertial navigation system is also called the inertial reference system. It is an autonomous navigation system that does not rely on external information and does not radiate energy to the outside (such as radio navigation). Its working environment Not only in the air, the ground, but also under water, the basic working principle of inertial navigation is based on Newton’s laws of mechanics. By measuring the acceleration of the carrier in the inertial reference frame, it integrates the time and transforms it into the navigation coordinates. In the system, information such as speed, yaw angle and position in the navigation coordinate system can be obtained.

Generally speaking, Micro-INS (Micro-Inertial-Navigation System) is a micro-inertial system based on Micro-Inertial-Navigation System (MEMS). Navigation System.

Microelectromechanical systems (hereinafter referred to as MEMS), also known as microelectromechanical systems, microsystems, micromachines, etc., are developed on the basis of microelectronics technology (semiconductor manufacturing technology), combining lithography, etching, thin film, LIGA, silicon. High-tech electromechanical devices made by micromachining, non-silicon micromachining and precision machining.
