abstract: "<p><code>UbxLogger</code> is a suite of shell scripts and executables for logging data from a U-blox ZED-F9P low cost GNSS receiver on OpenWrt routers and Single Board Computers such as the Raspberry Pi. Some of the things you can do with <code>UbxLogger</code> are</p><p><br></p><ul><li>Log data from one or more U-blox ZED-F9P receivers to a micro SD card, USB stick and/or disk partition</li><li>Compress the data and save to an archive directory</li><li>Optionally push the compressed data to a remote server over the Internet (requires LAN, WAN or 4-G connectivity)</li><li>Optionally convert the data to RINEX version 3 files, at a selectable sample rate and interval, compress using Hatanaka compression and gzip, archive and/or push to a remote server.</li><li>Start on (re)boot, monitoring and restart</li></ul><p><br></p><p>You have have the choice to create compressed RINEX files on OpenWrt (or SBC) and push the RINEX to the remote server, and/or push ubx rawdata files to the remote server and convert to RINEX on the remote server. To transfer the compressed RINEX files, especially at a lower sample rate, requires only a fraction of the bandwith compared to ubx.</p><p><br></p><p><code>UbxLogger</code> is designed to run on power efficient OpenWrt routers and Single Board Computers and is written entirely in shell script with a few pre-compiled c executables . It is known to work with</p><p><br></p><ul><li>The GL-iNet X750V2 (Spitz) OpenWrt 4G router</li><li>Raspberry Pi single board computer and Teltonika RUT240 4G router</li></ul><p><br></p><p>The total power consumption on the GL-iNet Spitz is below 3W, making this an ideal platform for solar powered operation.</p>"
