Statistical analysis was carried out in this work to estimate the zonal width (ZW) of low-latitude F-layer irregularities in the South of China by utilizing the 1-Hz carrier-to-noise density ratio (C/N 0 ) measurements of the B1I signals of the BeiDou Navigation Satellite System (BDS) geostationary earth orbit (GEO) satellites (i.e., C01-C04) gathered by two adjacent geodetic Global Navigation Satellite System (GNSS) receivers. We analyzed the C/N 0 measurements obtained at HKCL (22.296°N, 113.908°E) and HKQT (22.291°N, 114.213°E) sites during April 2014-April 2015. The two sites are equipped with the geodetic GNSS receiver Trimble NetR9 and are located nearly along the zonal (i.e., east-west) direction with a distance of ~31.38 km. Our statistical results showed that the occurrence rate of the events in which ZW < 24 km, 24 km ≤ ZW < 284 km, and 284 km ≤ ZW < 568 km was ~2%, ~44%, and ~54%, respectively. Our statistical results were in agreement with those of previous studies. Moreover, this investigation proved the viability of the approach, which deduces the zonal width of low-latitude F-layer irregularities by utilizing the 1-Hz C/N 0 data of the B1I signals of the BDS GEO satellites gathered by two adjacent GNSS receivers.
