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.

This post will discuss the effect of Earth rotation on Gyro at different locations on Earth viz. equator and pole when observed from space and Earth.

This post will discuss what is Gyroscope, its history, three Degrees of freedom in gyroscope and basic properties ‘Rigidity in Space’ & ‘Rule of Precision’.

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...

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...

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 of the Gyro spin axis initially points at some point X, which is above the Earth's...
