SUMMARY
This discussion focuses on the errors associated with gyroscopes in inertial navigation systems (INS) used in aircraft, specifically addressing transport wander, apparent drift, and the Coriolis effect. Transport wander refers to the positional inaccuracies that occur during the movement of the aircraft, while apparent drift is the perceived change in orientation due to various factors, including temperature and mechanical imperfections. The Coriolis effect, although not commonly used in modern systems, can introduce errors in gyroscope readings due to the rotation of the Earth affecting the gyroscope's measurements. Ring Laser Gyroscopes (RLGs) have become the standard technology for mitigating these issues over the past two decades.
