RMSEs of the Baseband GPS L5Q Signal Processing of the Traditional Receiver
PRN | DLL output; filtered code phase error (m) | PLL output; filtered Doppler frequency error (Hz) |
---|---|---|
6 (weak open sky) | 0.592 | 1.189 |
18 (weak open sky) | 0.473 | 0.914 |
Note: The bandwidths for the 3rd-order PLL and 2nd-order DLL are 18 Hz and 0.4 Hz, respectively. The receiver uses an early-late envelope code discriminator (early-late spacing: 0.5 chips) and a pure PLL discriminator. The coherent integration time is 20 ms.
