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.
