    <description descriptionType="Abstract">&lt;p&gt;This is a 15 second long recording of GPS L1 C/A signals done on 2022-03-27. To do the recording, a USRP B205 mini and GNU Radio 3.9 were used. The recording has a centre frequency of 1575.42 MHz and 4 Msps IQ 16-bit integer resolution. A small GPS patch antenna was used. The USRP was synchronized to the 1PPS output of a GPSDO connected to the same antenna, but its frequency reference was free-running.&lt;/p&gt;

&lt;p&gt;The recording was done to show how to process the GPS signals to obtain the timestamp of the recording. This can be seen in the post &amp;quot;&lt;a href="https://destevez.net/2022/03/timing-sdr-recordings-with-gps/(opens in a new tab)"&gt;Timing SDR recordings with GPS&lt;/a&gt;&amp;quot; by the author.&lt;/p&gt;

&lt;p&gt;The recording was done using GNU Radio metadata file format, and then converted to &lt;a href="https://github.com/gnuradio/SigMF"&gt;SigMF&lt;/a&gt; format. The original metadata detached header is included in the .hdr file.&lt;/p&gt;</description>
