Transequatorial Radio Propagation Monitoring

According to error of satellite signals traveling through the ionosphere, it can be impractical and receiver performance can be severely degraded. At times of high sunspot number, transequatorial propagation on ionospheric scintillations is most likely to occur during solar maximum, particularly affecting equatorial and auroral regions. Although isolated efforts have been reported, systematic analyses of the effects on positioning systems have not been performed. Auroral disturbances affecting north-south gradients can lead to effects at mid-latitudes. This paper presents initial monitoring results of a study on transequatorial radio propagation. A state-of-the-art SAO explorer, which extracts scintillation parameters from radio frequencies measurements, is being used
