Abstract :
The dominant sources of phase error in a GPS INS-aided PLL consist of the statistical part and the deterministic part, it is same to a GPS INS-aided FLL. The effects of two type sources are quantified and error models are built to evaluate tracking performance. The results of this research show that the INS-aided FLL performs better than the INS-aided PLL. The minimum C/N0 is 27.7dB-Hz for the third order PLL, 25dB-Hz for the INS-aided second order PLL and 17.1B-Hz for the INS-aided second order FLL(IFLL2) when the maximum value of line-of-sight jerk is 10g/s, so IFLL2 is more suitable for high dynamic receiver.
