Performance of 6 Different GNSS Receivers at Low Latitude under Moderate and Strong Scintillation

These data sets contain ionospheric scintillation (GPS L1) observations (S4 and \(\mathbf{\sigma_\phi}\) indexes) from 5 different GNSS receivers. The data are from two nights, 20/21 February and 27/28 November of 2013, and stored in different files. The files are in the HDF5 format using zlib compression and were generated by a Python script using the Pandas library. Each file contain the following folders: /csm_maker_calc /csm_own_calc /csm_raw /gpstation6_maker_calc /gpstation6_own_calc /gpstation6_raw /gsv_4004b_lisn_calc /gsv_4004b_maker_calc /septentrio_maker_calc /septentrio_own_calc /septentrio_raw /su_iono_sdr_own_calc /su_iono_sdr_raw The suffix maker_calc means that the indices were calculated in real time or post-processed using receiver manufacturer's tools. The suffix own_calc means that the indices were calculated using our own methodology. The suffix raw corresponds to the raw data (power and phase cycles). And finally the suffix lisn_calc corresponds to the S4 index obtained from the LISN network website.
