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.

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 […]
