Title: SIGNAL CAPTURE METHOD AND DEVICE, AND COMPUTER STORAGE MEDIUM
Abstract:
A signal capture method and device. The method comprises: acquiring a Doppler frequency offset and a transmission time of a captured strong signal satellite (S10); according to the Doppler frequency offset of the captured strong signal satellite, determining a Doppler frequency offset of a non-captured weak signal satellite (S11); according to the transmission time of the captured strong signal satellite, determining a spread spectrum code cycle and a spread spectrum code phase of the non-captured weak signal satellite (S12); and capturing the non-captured weak signal satellite using the Doppler frequency offset, spread spectrum code cycle and spread spectrum code phase of the non-captured weak signal satellite (S13).
