Types of Inertial Navigation Systems and Their Applications

Sometimes, you need the utmost accuracy when determining a specific occurrence’s location, motion, and altitude. Such are the instances when you’ll need to consider inertial navigation systems. These systems come in various types and are used in different settings. This article explores the types and applications of the system.

What Inertial Navigation Systems Are

An inertial navigation system combines angular rate sensors and accelerometers, which detect altitude, motion, and location. You can also rely on it to measure temperature, magnetic fields, velocity, and positions.

The Inertial Navigation System is essential when determining the balance and velocity of moving objects. Thanks to the accuracy provided, it becomes easier to monitor and control complex vehicles, including airplanes, UAVs, submarines, and spacecraft.

Types of Inertial Navigation Systems

There are two types of inertial navigation systems: strap-down systems and gimbaling systems.

A strap-down system is often comprised of gyroscopes and three accelerometers. The accelerometers help measure the speed of the aircraft in three different directions of travel. On the other hand, the gyroscopes determine the direction the vessel is facing.

The gimbaling system comes with a gimbal mounting, featuring accelerometers only. This system could also come with an isolated Inertial Measuring Unit, which maintains a fixed orientation in an inertial reference frame.

Applications of Inertial Navigation Systems

The Inertial Navigation System is vital in various industries. For instance, it could be used in tactical and strategic missiles, which will help calculate the motion and location of multiple projectiles. It is also critical during the navigation of aircraft and UAVs.

Further, INS comes embedded in smartphones, where it helps in tracking the location of the phone. What’s more, some experts use this system in motion capture. In conclusion, the Inertial Navigation System is an essential element when determining a moving object’s position, altitude, and motion. Thanks to its accuracy, INS remains a popular choice for experts.
