Spatial analysis of the correlation between scintillation parameters and MP&ROTI
conference contribution
posted on 2021-01-26, 13:46 authored by Chendong Li, Craig HancockCraig Hancock, Sreeja Veettil, Chong YouIonospheric scintillation, often described using the parameters S4 and σφ is one
of the most severe errorsources that influencesthe operation of Global Navigation Satellite
System (GNSS). However, these two parameters can only be generated by scintillation
monitoring receivers that have limited numbers around the world. This paper aims to
investigate the correlation between scintillation parameters and MP&ROTI (multipath &
rate of total electron content index) so that scintillation events can be represented by
parameters that can be obtained from standard receivers in order to research on
scintillation from a different perspective. Furthermore the utilization of these parameters
as a means of identifying scintillation events could facilitate the use of archived GNSS data
from non-scintillation receivers for improved ionosphere research. GPS data of one day
with strong scintillation is obtained from the station, SAO0P located in Sao Paulo, Brazil.
Time series plots and 2-D maps of all the parameters are utilized to respectively observe
the general and spatial relationship between the scintillation parameters and other
parameters. Furthermore, structural similarity (SSIM) generated between 2-D maps of
different parameters are applied to confirm the spatial similarity. The results show that the
high correlations between scintillation parameters and MP&ROTI are confirmed
temporally and spatially respectively based time series plots and 2-D maps.
