FAQ Answer

Question

How do tunnels and urban areas affect GPS tracking for rail inspection vehicles?

Answer

Total signal loss in tunnels creates data gaps. Systems without robust dead reckoning—using wheel encoders and gyros—will often draw straight lines between signal points, falsely showing the vehicle traveling off the tracks. Urban canyon multipath can bounce signals around, placing the vehicle on a parallel street instead of the rail right-of-way.
