Abstract: Disclosed are a multiple satellite navigation signal combining device, and a signal processing device comprising same. The multiple satellite navigation signal combining device comprises: a plurality of reception antennas for receiving satellite navigation signals from a satellite; a time delay unit for setting one satellite navigation signal, among the satellite navigation signals received by means of the reception antennas, as a reference satellite navigation signal and time-delaying other satellite navigation signals excluding the reference satellite navigation signal; and a signal combining device for combining the reference satellite navigation signal and other satellite navigation signals that have been time-delayed and transmitting same to a global navigation satellite system receiver.
