What is another word for inertial navigation?
Pronunciation: [ɪnˈɜːʃə͡l nˌavɪɡˈe͡ɪʃən] (IPA) 
Inertial navigation is a technology that helps to navigate an object accurately without relying on external references such as GPS or radio signals. There are various synonyms for inertial navigation, including strapdown, gyrostabilized, IMU-based, and INS. Strapdown navigation refers to the use of accelerometers and gyros mounted to a rigid body to measure changes in acceleration and rotation. Gyrostabilized navigation uses a stabilized platform to maintain constant orientation with respect to the earth's surface. IMU-based navigation is based on an inertial measurement unit that combines accelerometers and gyroscopes to measure changes in velocity and orientation. INS or inertial navigation system is a broader term that includes all the aforementioned technologies and is widely used in aviation, aerospace, and naval navigation.
