Abstract
A method and apparatus are provided for demodulating a B2b signal from a satellite in the BeiDou Navigation Satellite System. The method comprises tracking a first signal transmitted in a first GNSS operational band by the satellite, to estimate one or more parameters of the first signal; predicting, based on the estimated one or more parameters of the first signal, one or more parameters of the B2b signal transmitted by the satellite; and demodulating the B2b signal to obtain data bits of a data message modulated on the B2b signal by the satellite. The demodulating is based on the one or more predicted parameters of the B2b signal.
