TABLE 4

RMSEs of the Baseband GPS L5Q Signal Processing of the Traditional Receiver

PRNDLL output; filtered code
phase error (m)
PLL output; filtered Doppler
frequency error (Hz)
6 (weak open sky)0.5921.189
18 (weak open sky)0.4730.914
  • 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.
