Terrestrial Radio Navigation System topics include: Radio propagation, noise characteristics, point source and hyperbolic radio systems. Terrestrial radio navigation systems (TRNS) are networks of synchronized transmitters that broadcast signals that can reach the interior of buildings. TRNS are similar to GNSS satellites and can provide navigation services for indoor or urban users. TRNS work by using a signal sent by a mobile transmitter-receiver-indicator unit, which is then returned to the unit by a fixed transponder. The round trip time is then converted into distances.

TRNS work by using a signal sent by a mobile transmitter-receiver-indicator unit, which is then returned to the unit by a fixed transponder. The round trip time is then converted into distances. Some examples of TRNS include: Loran-A: A long-range navigation system that is used to navigate aircraft and ships. It operates in the low frequency radio spectrum from 90 to 110 kHz. R-Mode (Ranging Mode): A proposed backup navigation system that uses ranging signals from existing maritime infrastructure. This could include medium frequency (MF) radio beacons and/or AIS base stations Show less
