The application relates to the satellite navigation signal, generating method, generating device, receiving method and receiving device. The navigation satellite signal generating device includes a baseband signal generator, a multiplexed signal generator and a modulator. The baseband signal generator is provided to generate a first baseband signal S 1 , a second baseband signal S 2 , a third baseband signal S 3 , and a forth baseband signal S 4 . The multiplexed signal generator is provided to set an amplitude and a phase of an in-phase baseband component and an amplitude and a phase of a quadrature-phase baseband component of a signal into which the first baseband signal S 1 , the second baseband signal S 2 , the third baseband signal S 3 and the forth baseband signal S 4 are multiplexed, so as to generate a multiplexed signal with constant envelope. The modulator is provided to modulate the multiplexed signal with constant envelope to a radio frequency, so as to generate the navigation satellite signal. The first baseband signal S 1 and the second baseband signal S 2 are modulated to a first carrier frequency f 1 with carrier phases orthogonal to each other, and the third baseband signal S 3 and the forth baseband signal S 4 are modulated to a second carrier frequency f 2 with carrier phases orthogonal to each other. |
