Abstract: The spaced-receiver technique is an inexpensive approach for monitoring plasma motions via trans-ionospheric radio waves during ionospheric scintillations. A closely spaced high-rate GNSS receiver array has been established for this purpose at Poker Flat, Alaska since 2014, where phase fluctuations are more frequent and intense than amplitude scintillations. Our previous studies discovered that both the conventional time-domain method and a time-frequency-domain method are capable of estimating the irregularity drift via cross-correlation techniques. In this study, both methods are applied to the Poker Flat GNSS array data collected during two prominent phase scintillation events on 2015/12/20 and 2015/12/31, respectively. Moreover, the GLONASS constellation is included in the analysis in additional to the GPS and Galileo satellites. A comparative study is conducted between the time-domain and the time-frequency-domain methods on all the above GNSS signals. The estimated irregularity drift velocities are further cross-compared with the measurements from the Poker Flat Incoherent Scatter Radar.
