GPS tunnle
Abstract:
This thesis recommends how to transmit a GPS signal down a specific tunnel in Norway. The recommendation is based on two mathematical models set up for GPS signal behavior analysis in tunnels: one is for a straight tunnel using a Ray-Launching/Ray-Tracing technique; the other is for a curved tunnel using waveguide solutions. Both models are verified with data from research papers. A hybrid model is created to simulate the tunnel in Norway. Based on the hybrid model, it is recommended that four GPS repeaters be placed to ensure signal coverage throughout the tunnel in Norway.
