N2 - UbxLogger 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 UbxLogger are
- Log data from one or more U-blox ZED-F9P receivers to a micro SD card, USB stick and/or disk partition
- Compress the data and save to an archive directory
- Optionally push the compressed data to a remote server over the Internet (requires LAN, WAN or 4-G connectivity)
- 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.
- Start on (re)boot, monitoring and restart
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.
UbxLogger 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
- The GL-iNet X750V2 (Spitz) OpenWrt 4G router
- Raspberry Pi single board computer and Teltonika RUT240 4G router
The total power consumption on the GL-iNet Spitz is below 3W, making this an ideal platform for solar powered operation.
