Inertial navigation systems are used in high-end defence, space, and naval applications, and in commercial vehicles.
These systems are used in navigation applications, where accuracy and performance are of utmost importance, along with the size and cost. The inertial navigation system market is forecasted to witness prominent growth in the near future, due to increasing advancement in technology pertaining to navigation systems.

Innovation has led to the introduction of technology enabled advancements in military, and naval applications, such as fiber optic gyro (FOG), ring laser gyro (RLG), and micro-electro-mechanical systems (MEMS) that have provided light and small inertial navigation systems. Some of the prominent players in the defence equipment business have in-house manufacturing facilities with limited applications.
Strap down and gimballed are the two types of inertial navigation systems available in the market. In the strap down system, all the sensors are mounted parallel to the body axes of the vehicle.
In this system, the gyroscopes don’t provide a stable platform; they are used to sense the turning rates of the craft. Whereas in the gimballed system, the platform is mounted on gimbals.
The strap down system contributes fewer moving parts and it is simple and more reliable, as compared to other systems.

An inertial navigation system (INS) comprises gyroscopes and accelerometers, which help it track the orientation and position of an object with reference to a known starting point. The gyroscope is used to measure the angular velocity of the frame with the sensor.
Whereas, the accelerometer is used to measure the acceleration of the moving object in the frame. Based on this, one can identify the vehicle’s direction, i.e.
whether it is moving backward, forward, left or right. By tracking both, the current linear acceleration of the system and the current angular velocity of the system relative to the moving object, the relative orientation of an object and its position can be derived.
North America and Europe hold a relatively large market share and their dominance is projected to continue over the forecast period, owing to large investments in naval vessels and warships, and defence aircraft. APAC and the Middle East collectively hold the second spot in terms of market share, which can be attributed to the launch of many programs on inertial navigation systems (INS).
Many countries are interested in investing in the navy and defence sector to strengthen their forces. The inertial navigation systems market hold a huge potential opportunity of application in unmanned vehicles.
The demand for unmanned vehicles is increasing, which drives the inertial navigation systems market. Hence, the demand for remotely operated underwater vehicles, and autonomous underwater vehicles is expected to drive the market growth of inertial navigation systems.
