What is Terrestrial Navigation System?
The terrestrial navigation system is a national core infrastructure that provides position, navigation, and timing needed in various public and private fields such as finance, power, and transportation.
The advanced terrestrial navigation system is a backup and substitute navigation system that improves the position accuracy and stability, which are shortcomings of the existing Loran system, and can provide position, navigation, and timing even when GPS is disturbed.
