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.

Degaussing
The potency of a magnetic field is measured in terms of Gauss. Accordingly, if we define Degaussing. We can say that degaussing means the procedure to diminish the potency of a magnetic field. Any ship made from steel or a material having magnetic susceptibility is like a big floating magnet with a very high magnetic […]
Ring Laser Gyro
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 […]
Damped Oscillation
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, one at each end of the damper) partially filled with […]
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 the acceleration and its rotary motion it is sensing. The acceleration is measured […]
Types of EMI
EMI stands for Electromagnetic Interference. It is a generalization of an older terminology RFI (Radio Frequency Interference). EMI can be defined as an electromagnetic or electro static disturbance that causes malfunctioning or undesired response in one or more electronic system, equipment or circuit. In this post, we will focus on the different types of EMI. […]
Responsibilities of Reliability Engineer
One of the most important responsibilities of Reliability engineer is that he has to work in coordination with other Project engineers so as to ensure reliability, maintainability, availability, parts control, obsolescence management, configuration control etc of new product designs as well as improved designs of old products.
Role of Reliability Engineer
The main role of Reliability Engineer is identification and management of the reliability risks that may have a negative impact on production or post production operation of the product. This can be further split into three main sub categories i.e. Loss identification and reduction, Risk management and Product life cycle support management. Loss Identification and […]
Difference between Quality and Reliability
Quality is a much broader aspect than Reliability. Quality covers almost everything from organisation, managements, service, procedures, people, product, product-life etc. In simple words, Reliability is only a subset of quality, the others being performance, consistency, efficiency, user experience etc. Whereas, Quality is the measure of conformance to laid down product specification. Not understood? Tricky […]
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 have no effect as there is no […]
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. The free gyro does not contain any instrument which may be called a compass. The direction of the spin axis relative to the earth’s’ surface continually […]
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:- Path traveled by F1= 2πR+AB Path traveled by F2= 2πR – AB Difference in Path Length i.e. ∆L = 2AB or ∆L = 2RӨ (Since […]
