Abstract
A transmitting system, which is capable of transmitting a signal for positioning to an area where radio waves are hardly received, is provided. The transmitting system for transmitting the signal for positioning includes a GPS compatible mixer combining a GPS signal for positioning received by a GPS antenna and a BS broadcasting signal received by a BS antenna and outputting the combined signal, a BS-IF compatible amplifier amplifying the signal output from the GPS compatible mixer and outputting the amplified signal, a separator separating the signal output from the BS-IF compatible amplifier into a BS broadcasting signal and a GPS signal, a BS tuner receiving an input of the BS broadcasting signal output from the separator and obtaining a signal of a channel tuned by a user, a GPSBP filter passing a GPS signal included in a predetermined frequency band out of the signal output from the separator, and a GPS issuing unit.
