inertial navigation system

Japanese: inertial navigation system(英語表記)inertialnavigationsystem
inertial navigation system

...A navigation method that determines one's position based on detected acceleration, using an inertial navigation system (INS) consisting of an accelerometer that measures three-dimensional acceleration and a computer that calculates speed, distance traveled, etc. from this acceleration. Unlike conventional navigation based on celestial measurements or navigation based on radio waves from ground stations, it does not require external assistance, so it can calculate and display various navigation parameters including the current position in a short time without being affected by external factors such as bad weather or radio interference, and aircraft equipped with an inertial navigation system do not require a pilot.

*Some of the terminology that mentions "inertial navigation system" is listed below.

…検出した加速度を基に自分の位置を求める航法で,三次元の加速度を測定する加速度計およびこの加速度から速度,移動距離などを計算するコンピューターなどから成る慣性航法装置(INS。inertial navigation systemの略)を用いる。従来の天体測定による航法,あるいは地上局からの電波による航法と異なり,外部からの援助を必要としないので,悪天候,電波障害などの外界の影響を受けることなく,短時間に現在位置を含む種々の航法諸元を算出表示することができ,慣性航法装置を装備した航空機では航空士を必要としない。…
