Satellite signal capturing method and receiver

The invention relates to a navigational positioning system, and discloses a satellite signal capturing method and a receiver. The satellite signal capturing method comprises: trying to capture the satellite signals of a satellite to be tracked by a receiver, and detecting whether the satellite signals have cross-correlation characteristic after the satellite signals of the satellite to be tracked are captured; if detecting that the satellite signals have cross-correlation characteristic, judging that capture is unsuccessful, and continuously trying to capture the satellite signals of the satellite to be tracked; if detecting that the satellite signals do not have cross-correlation characteristic, judging that capture is successful, and then tracking the satellite and decoding the satellite signals. Whether the satellite signal is successfully captured is judged through detecting that whether the captured satellite signals have cross-correlation characteristic, so that the receiver can timely recognize that wh
