Abstract: A pseudo satellite navigation signal repeating device includes a communication interface configured to collect orbit information of navigation satellites from a global navigation satellite information server through a network, a controller configured to calculate pseudo ranges from associated navigation satellites based on associated orbit information of the associated navigation satellites among orbit information of all the navigation satellites, a signal generator configured to generate global navigation satellite baseband digital signals of the associated navigation satellites based on the pseudo ranges, a signal converter configured to convert the navigation signals into analog baseband or intermediate frequency band signals, and a modulator configured to modulate the analog baseband or intermediate frequency band signals using a wireless carrier signal.
