Hello!
My current base station setup uses a raspberry pi, but still requires a Windows 10 PC to perform the initial 24 hour PPP survey. I would like to get rid of this requirement and use something like the OpenLog Artemis to log the RAW data instead. I’ve ran into a couple of issues and am hoping that someone can help me figure this out.
I’ve upgraded the firmware to OpenLog_Artemis_GNSS_Logging-V10-v22.bin following the README in the Sparkfun/OpenLog_Artemis_GNSS_Logger GitHub and followed the GNSS logging configuration instructions found in another forum post: viewtopic.php?f=116&t=57658
Problem 1:
Logging only starts when connected to the OpenLog Artemis using a terminal emulator. I can view the logging entries in real time when connected, and dataLogs are properly stored on the MicroSD card when I’m connected to it. However, when I power down the GPS Chip and the OpenLog, disconnect from it, and then power up the GPS Chip and OpenLog without a computer connection, nothing gets logged to the MicroSD card. Am I doing something wrong, or is there a way to enable automatic logging on power-up?
Problem 2:
The .ubx files stored on the MicroSD card do appear to be correct. However, when I convert them using rtkconv (RTKLIB) I get a really weird error message:
I do get a .obs file output that looks the same as when I’m processing a log file captured by u-center, so I’m not sure what’s going on here. (I did verify that this error occurs both on my main Win10 VM and a native Win10 PC so my assumption is that something is weird about the .ubx file from the OpenLog)
If I can get it working so that I can just connect the OpenLog Artemis to a GPS-RTK-SMA board and disconnect it 24 hours later with a valid PPP survey .ubx file on the MicroSD card it would be amazing.
Any help would be greatly appreciated!
