Inertial navigation tracks the position of an object by measuring and comparing the distance it travels with the accelerations in various directions it experiences while moving. For clarification, gyroscopes are used that, once spun up, tend to remain in one position (like the gyroscopes we played with as kids). When the gyroscope position is moved, sensors detect the direction, speed, and duration (vector) of the movement which is then calculated to determine a resultant change in position of the gyroscope. Inertial Navigation Systems (INS) have a built in error due to the precessing (caused by the earth's movement) that all gyroscopes experience. In aircraft, this error can be as much as a half a mile per hour. Over a 5 hour flight, for instance, an INS could be 2.5 miles off and still be considered good. By comparison, a GPS over the same period of time will usually have an accuracy of 30 yards or less. For this reason, and the fact that inertial navigation systems are quite expensive, INS is no longer considered state of the art technology.

What are the disadvantages and advantage of inertial Navigation System?
Advantages: Inertial Navigation Systems are self-contained and do not rely on external signals, making them robust in GPS-denied environments. They provide real-time data on an object's position, velocity, and orientation. Disadvantages: Inertial Navigation Systems experience drift errors over time, causing inaccuracies in long-duration navigation. They are also costly and complex to set up and maintain.

Difference between inertial navigation system and inertial reference system?
Inertial Navigation System (INS) refers to a system based on dead reckoning, that integrates several sensors in order to calculate your position. If you know your previous position,lets say 1 second ago, and you know your speed and direction then you can determine where you are now. An inertial reference system, in terms of geodesy refers to a coordinate system that does not move with the Earth, it has its axis oriented to fix points outside of Earth. Inertial Reference coordinate systems are used for position of bodies outside of Earth

What is bassic navigation principle?
The basic principle in Navigation is to plot the path from where you are, to where you wish to go. This would be practiced by backpackers, ship's Captains, Aircraft, etc. You will probably use some instrumental aid, such as map and compass, a GPS system, an inertial navigation system, and so on.
How do planes know where they are going?
Planes determine their location and flight path using a combination of navigation systems, including GPS, inertial navigation systems, and radio navigation aids. GPS provides precise positioning data based on satellite signals, while inertial systems use onboard sensors to track movement. Additionally, pilots follow air traffic control instructions and use flight plans that include waypoints and routes to ensure they stay on course. Together, these systems enable accurate navigation from departure to destination.
What is the Integrated Navigation System?
The Integrated Navigation System (INS) is a sophisticated technology that combines various navigation methods and sensors to provide accurate positioning and guidance. It typically integrates data from GPS, inertial navigation, and other sources such as radar and sonar to enhance reliability and precision in navigation. Used in various applications, including aviation, maritime, and autonomous vehicles, INS helps improve situational awareness and navigational accuracy in diverse environments. Its ability to function in GPS-denied situations makes it particularly valuable for military and critical operations.
