Abstract

This research is aiming for cycle slip detection and correction in case of ionospheric scintillation. Different from the normally discussed situation without ionospheric scintillation, ionospheric delay cannot be neglected due to abrupt ionosphere change. In this case, ionosphere-free testing quantities for cycle slip detection and correction have to be used. In the past research, several geometry-free and ionosphere-free testing quantities have been proposed and in every of them, code measurements are involved. So these geometry-free and ionosphere-free testing quantities are sensitive to code observation noise and multipath. In this research, non-geometry-free and ionosphere-free testing quantities are proposed. Different from previously proposed, the code measurements are not longer involved. Detailed discussion on cycle slip detection and correction in case of ionospheric scintillation are given and method using the new proposed non-geometry-free testing quantities in combination with one previously proposed geometry-free & ionosphere-free wide-lane testing quantity is described. The cycle slip detection and correction performance may not be very reliable with the new proposed method. But it is expected that this research will benefit for future work in this aspect.
