| Abstract: | A parallel tracking algorithm based on GPU computing is presented for GNSS signals. The experiments show that the speedup of the new method based on GPU is up to tens times than traditional algorithm based on CPU and it goes up with the increase of the number of tracking channels. The research shows that the multi-mode GNSS SDR receiver is becoming possible. |
