UAVs as aircraft, an inanimate physical presence, how to sense the state of the outside world, which depends on the sensor. A sensor is a measuring device that can be sensitive to the information being measured and converted into an electrical signal or other required form of information output according to a certain protocol to meet the requirements of information transmission, processing, storage, display, recording and control. In other words, this is equivalent to the five senses of human beings and is a very important sensory system. It can help the aircraft to judge its own movement, the external atmosphere, and the distribution of obstacles around it. Today, one of the types of navigation sensors, the inertial navigation system, is introduced.
The motion of an aircraft can be described in two categories. One is the movement of the centroid (referred to as an imaginary point on the material system where the mass is considered to be concentrated), also known as line motion, and the associated navigation parameters are flight speed, position, etc.; One type is the rotation of the airplane around the center of mass, also known as angular motion. The corresponding navigation parameters include the attitude angle and heading angle of the aircraft.
Inertia is the basic property of all mass bodies. All inertial navigation systems based on the principle of inertia do not require any external information. The system itself can perform autonomously and covertly in a global and all medium environment under all weather conditions. 3D positioning and 3D orientation. Therefore, inertial navigation is an essential navigation device that is indispensable for important carriers.
