W-code enhanced cross correlation satellite positioning system receiver |
摘要 |
The present invention relates to the new W code enhanced GPS receiver which allows to receive and demodulate the L1 and L2 satellite signals encrypted with the unknown Y code. No assumptions are made about the timing or the structure of the unknown Y code. The signal-to noise ration is not compromised in comparison with the reception of the L1 and L2 signals without code encryption.
