abstract: "<p>RINEX3 (https://files.igs.org/pub/data/format/rinex305.pdf) Hatanaka-compressed (http://sopac.ucsd.edu/hatanaka.shtml) GNSS (Global Navigation Satellite System) data of single-frequency observations obtained by the Ublox Neo M8T receiver (Evaluation Toolkit) and standard Ublox patch antenna.</p>
<p><br></p>
<p>The data is downsampled to 15-second observations spanning from DOY (day of year) 95 in 2017 to DOY 83 in 2020.</p>
<p><br></p>
<p>The unit was placed on the rooftop of the observatory of the NMi building in Delft (approx. coordinate 51.986166, 4.387678).</p>
<p><br></p>
<p>The receiver was connected to a constant power supply. The antenna was placed on the flat rooftop (no  significant obstruction in the sky) with a 10cm circular glound plane underneath.</p>"
