Ionospheric scintillations can degrade the performance of GNSS receivers by causing fading in the amplitude and phase of transi‐ionospheric GNSS signals.Considering the current solar maximum,a research project was established between the Brazilian Institute of Geography and Statistics (IBGE),the University of the State of Rio de Janeiro,and the Position,Location and Navigation (PLAN) Group at the Department of Geomatics Engineering,University of Calgary (UofC),to investigate the effects of equatorial ionospheric scintillation on GNSS signal tracking performance and measurement quality with the latest receiver technology.The multi‐constellation multi‐frequency GNSS Software Navigation Receiver (GSNRx?) developed by the UofC PLAN Group was used in this project due to its multi‐constellation multi‐frequency processing capability and its flexibility to adopt the latest receiver technology to track GNSS signals under strong equatorial scintillation.A so‐called shared‐channel architecture,which supports the inter‐frequency and inter‐satellite code/carrier aiding,has been implemented in GSNRx?.Based on the data collected during this project,GSNRx? produced no actual cycle slips in the processed datasets and only up to 4% of L2 carrier phase observations missing,indicating that this shared‐channel architecture is well resistant to equatorial ionospheric scintillation,whereas for the reference commercial hardware receiver 13% of L2 carrier phase observations missing under strong scintillation.In the position domain,computing Precise Point Positioning solutions using L1 code observations gave very similar results for the software and hardware receivers,with the ionosphere being responsible for degrading coordinate accuracies up to a factor of 12.
