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 the acceleration...

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...

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:-     Path traveled by F1= 2πR+AB Path traveled by F2= 2πR - AB Difference in Path Length i.e. ∆L  =  2AB or ∆L =...

The Ring laser gyro (RLG) functions in the following way : The laser generates a very coherent beam of light. This concludes that since the source is same, the generated photons are at one specific frequency. The beam is split into two beams that...

The process of producing damped oscillation of Gyro and its various phases are as follows: By adding an additional weight to the lower part of the Gyro sphere, We can provide it the pendulum effect. This is done by placing a damper (with two pots,...

Till now we have learned about the free gyro. Now, We will learn how to restrict the free Gyro from drifting and tilting. To do so, We need to address certain issues which plays a significant role in converting a free Gyro to a...
