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

<p>These data sets contain ionospheric scintillation (GPS L1) observations (S₄&nbsp;and <span class="math-tex">\(\mathbf{\sigma_\phi}\)</span>&nbsp;indexes) from 5 different GNSS receivers.</p> <p>The data are from&nbsp;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.</p> <p>Each file contain the following folders:</p> <ul> <li> <p>/csm_maker_calc</p> </li> <li> <p>/csm_own_calc</p> </li> <li> <p>/csm_raw</p> </li> <li> <p>/gpstation6_maker_calc</p> </li> <li> <p>/gpstation6_own_calc</p> </li> <li> <p>/gpstation6_raw</p> </li> <li> <p>/gsv_4004b_lisn_calc</p> </li> <li> <p>/gsv_4004b_maker_calc</p> </li> <li> <p>/septentrio_maker_calc</p> </li> <li> <p>/septentrio_own_calc</p> </li> <li> <p>/septentrio_raw</p> </li> <li> <p>/su_iono_sdr_own_calc</p> </li> <li> <p>/su_iono_sdr_raw</p> </li> </ul> <p>The suffix <strong>maker_calc</strong> means that the indices were calculated in real time or post-processed using receiver manufacturer&#39;s tools. The suffix <strong>own_calc</strong> means that the indices were calculated using our own methodology. The suffix <strong>raw</strong> corresponds to the raw data (power and phase cycles). And finally the suffix <strong>lisn_calc</strong> corresponds to the S₄ index obtained from the LISN network website.</p>
