资源简介：
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.
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 "Timing SDR recordings with GPS" by the author.
The recording was done using GNU Radio metadata file format, and then converted to SigMF format. The original metadata detached header is included in the .hdr file.
