Abstract
In the ultra-tightly integrated navigation system, inertial navigation aids to carrier loops can improve the tracking speed and accuracy of GPS receivers effectively. Carrier loop using second-order Frequency-locked Loop (FLL) to aid third-order Phase-locked Loop (PLL) is under-researched in ultra-tightly INS. This paper analyses the basic structure of the carrier loops and derives the error expression of FLL-assisted PLL with inertial navigation aids theoretically. Analysis results and simulations represent that the better tracking efficiency is obtained by FLL-assisted PLL, while its phase vibration error is not rebounded when the loop bandwidth increases to a certain extent.
