I have a problem of getting reliably data from Drotek Tiny M8P with RTKLIB, more specifically with rtkrcv app.
I’m trying to use M8P on a UAV as a logging unit on Linux machine to consequently use the log for PPK solution. 4 times out of 5 it works just fine and log the data into UBX file, but sometimes the following problem occurs when I start rtkrcv - I would receive 0 of rover satellites and it would never get more satellites/lock until I repower the M8P module. What I found so far:
- it’s not a signal/antenna problem. The problem appears while keeping the same position with a previously perfect lock.
- as long is it appears once the only way to solve it is to re-plug the USB cable.
- when the issue appears, rtkrcv working just fine and keep logging into UBX log file (but of course it’s logging data with no satellites)
Linux, Ubuntu 16, rtklib 2.4.3 b31, Tallysman antennas. Settings on Ublx are default, I only tried changing cold/warm start, but it doesn’t solve the issue.
Here is the content of .conf file (taken from Emlid modules) and here is the content of .cmd file, both are used to start rtkrcv.
Did anyone encounter a similar problem?
Do you change Ublox default settings?
Could you please confirm that your .conf/.cmd looks similar?
Thank you in advance and I would be thankful for every input!
