RLG SIGMA 40 is based on Ring Laser Gyroscope technology. RLG is a type of gyroscope based on the principles of interferometry and the Sagnac effect, which is a relativistic phenomenon in the theory of electromagnetic fields. In this article, we learn details about RLG SIGMA 40, its features, core aim, and the units.
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 travel the same path but in opposite directions: one clockwise and […]
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 of system, the gyroscopes do not provide […]
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 and its rotary motion it is sensing. The acceleration is measured […]
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 = 2RӨ (Since […]
