Abstract:	Our previous work has demonstrated that GPS L1 signal carrier phase fluctuations observed from a spaced receiver array can be used to estimate ionosphere irregularity horizontal drift velocities. The gist of the approach is to use a joint frequency analysis technique to generate high-resolution timevarying spectrum information for the disturbed signal carrier phase. The objective of this paper is to expand upon the previous efforts by applying the same approach to other GNSS signals. Such an expansion allows the study of the self-consistency of the method and the observation of similarities / differences of GNSS signal diffraction patterns between irregularities structures at different physical scales. The focus of this study is on analyzing the irregularity drift velocity estimations from GPS L1 and L2C signals. Estimation results from GPS L5 and GLONASS L1/L2 bands are also studied based on one of the receiver array pairs.
