Provided are a satellite navigation signal and a generation method, generation device, receiving method and receiving device for a satellite navigation signal. The satellite navigation signal generation device comprises a baseband signal generator, a multiplexing signal generator and a modulator. The baseband signal generator generates a first baseband signal S1, a second baseband signal S2, a third baseband signal S3 and a fourth baseband signal S4. The multiplexing signal generator sets the amplitudes and phases of in-phase baseband components and quadrature baseband components of a multiplexing signal of the first baseband signal S1, the second baseband signal S2, the third baseband signal S3 and the fourth baseband signal S4, so as to generate a multiplexing signal having a constant envelope. The modulator modulates the multiplexing signal having the constant envelope to a radio frequency to generate a satellite navigation signal. The first baseband signal S1 and the second baseband signal S2 are modulated at a first carrier frequency fand their carrier phases are orthogonal to each other, and the third baseband signal and the fourth baseband signal are modulated at a second carrier frequency and their carrier phases are orthogonal to each other. |
