Effect of Earth Rotation on Gyro – At Equator and Pole

Effect of Earth rotation on Gyro must be understood by us to evolve our free gyro into a Gyroscope. It needs no explanation that our Earth has its own magnetic field. Every object on/ at Earth is influenced by its magnetic force. So does our free Gyro. This post will ...

What is Gyroscope – History, Three Degrees of Freedom, Basic Properties

Gyroscope is one of the 'must be' navigational equipment that any floating vessel needs for finding direction. Every mariner knows its importance. Not limited to this, it also finds it uses in Smart watches, Smartphones, Gaming Industry and Cameras too. This post will discuss what is Gyroscope, its history, three ...

Undamped Oscillation of Gyro

In our earlier posts, we discussed about the free gyro, Gyroscope conversion, damped oscillation and its settling period. In this post, we will discuss about undamped oscillation of Gyro.

Settling Period of Gyro

In our earlier posts, we discussed about the free gyro, Gyroscope conversion and its damped/undamped oscillations. In this post, we will discuss about Settling period of Gyro. When the compass is settled, the spin axis has a constant tilt. The delaying action of the damping arrangement will therefore ...

Path traced by Gyroscope

The path traced by Gyroscope is elliptical in nature and is finally settled towards the meridian. Lets find out how. Path traced by north end of Gyroscope The north end ...

Displacement type Accelerometer

Displacement type Accelerometer As in the case of normal navigation systems, The Inertial Navigation system is not dependent on the external fields or forces. In place of that, an Inertial Navigation system always keeps on tracking its location by precise measurement of ...

Strapdown System

Lightweight digital computers permit the system to eliminate the gimbals, creating strapdown system, and are called so because their sensors are simply strapped to the vehicle. In a strapdown inertial navigation system the accelerometers are rigidly mounted parallel to the body axes of the vehicle. In this type ...

Sagnac Effect

Sagnac effect : The Difference in path Length (∆L) is directional proportional to Angular Rotation (ω). When course is steady:- Path traveled by F1=2πR Path traveled by F2=2πR When Course changes:-

RLG Sigma 40

RLG SIGMA 40 is an inertial navigation system which is based on Ring laser gyro technology. This system has state of the art technology which is completely advanced and rugged. This system has been designed by ...

Damped Oscillation

The process of producing damped oscillation of Gyro and its various phases are as follows: [caption id="attachment_110" align="aligncenter" width="569"] Damped Oscillation[/caption] By adding an additional weight to the lower part of the Gyro sphere, ...
