Abstract:	It is well known that ionospheric plasma irregularities cause GNSS signal amplitude and phase fluctuations, collectively referred to as ionospheric scintillation, which impact GNSS receiver carrier tracking performance. Understanding of the effect of ionospheric scintillation on GNSS signals is essential to the development of robust GNSS receivers during ionosphere disturbances and the effective utilization of GNSS to monitor and study ionosphere space weather phenomena. There have been extensive efforts in recent decades in studying ionospheric scintillation effects on GPS signals. Recent progress in international GNSS is making it possible to obtain ionospheric scintillation data on other satellite signals. Clearly, ionosphere monitoring and space weather studies will greatly benefit from the increased number of all GNSS satellite signals in space. In this paper, we present real ionospheric scintillation observed on BeiDou B1I signals collected during a March 2013 experimental campaign on Ascension Island (S7.9°, W14.4°) and the software receiver signal processing algorithm developed to track BeiDou B1I signals during strong scintillation. The results will be compared with concurrent measurements obtained using a Septentrio PolaRxS receiver. Performance evaluations of the signal processing algorithm using different tracking parameters implemented in the software receiver will also be presented.
