Abstract:	Ionosphere scintillations can cause significant amplitude and/or phase fluctuations of GNSS signals, causing potential performance degradations. This paper presents the evolvement of a high-performance GNSS monitoring setup installed at HAARP, Alaska. Recent enhancements to the GNSS monitoring system include multi-constellation monitoring, advanced event triggering, multi-band RF recording, and an expansion of the GNSS receiver array. The enhanced observability of the monitor installation combined with the increasing solar activity produces a wealth of data. Data analysis of both the commercial receiver outputs as well as that of the recorded RF data is an ongoing task. This paper describes recent findings, such as: the relation between ionosphere-scintillation induced amplitude fading on L1, L2, and L5, the correlation between phase and amplitude scintillations for natural disturbances, and the presence of phase scintillations during controlled heating experiments.
