INS : Gyroscope errors : transport wander, apparent drift , coriolis effect ?

AI Thread Summary
Transport wander refers to the gradual drift of a gyroscope's output due to the movement of the sensor through varying gravitational fields, affecting its accuracy. Apparent drift occurs when the gyroscope indicates a change in orientation that is not actually present, often caused by misalignment or external forces. The Coriolis effect introduces errors in gyroscope readings due to the rotation of the Earth, impacting the perceived motion of the gyroscope. Ring laser gyroscopes (RLGs) have largely replaced traditional gyroscopes in inertial navigation systems due to their superior accuracy and reliability. Understanding these errors is crucial for improving navigation system performance in aircraft.

can anyone please explain me following errors of gyroscopes used in inertial navigation systems of aircraft :
a) what is transport wander , how actually it happens ?
b) what is apparent drift in gyroscope ?
c) what is coriolis effect and how it causes errors in gyroscopes ?

Not used anymore. RLGs (ring laser gyroscopes) have been the standard for the last 20 years.
 

Thread 'Radiation Hard Electronic Design for LVO Long Mission'

Venus does not have a magnetosphere, so the Galactic Cosmic Rays (GCRs) environment shall be much worse than in a LEO environment. Looking to the std radiation models for Venus, the standard radiation-hard space level electronic component with tested immunity LET = 85 MeV-cm2/mg seems not enough, so, for example, a 1cm2 Si die will suffer considerable flux above this level during a long mission (10 years for example). So, the question is, usually we are not paying attention to latch-up...

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
