So I’ve got maybe 50 flights and tons on bathymetry scans in the first month I’ve owned the RS2 and M2. Everything has always been a fix solution in PPK. That was until yesterday. First flight is 100% float. Worst I’ve seen so far is maybe a few seconds of float after taking off. Weird thing, if I process it backwards and increase the elevation mask I get almost 100% fix.
If you share the logs, I’ll be happy to check if there some obvious reason from looking at the data collected.
That would be great. I’d like to learn more about diagnosing issues like this. Here’s a link to the UBX files for the base and rover.
Known manually input coordinates are:
49 21’07.15136
120 30’43.578321"
1094.342m
Hi Shaun,
What settings did you use in post-processing? I’ve processed the logs you shared in Emlid Studio and achieved a 99.9% Fix with default settings.
With the Combined filter type, I got 100% of Fix. At the same time, the Backward filter type gave 65% of Fix.
By changing the filter type, you change how Emlid Studio goes through the raw data and calculates the solution. Thus, it’s ok that the result adjusts accordingly. And this is also a great possibility of the PPK: you can find the combination of settings that gives you the best results.
Thanks to both of you for running that! I checked the setting’s and they were at the default. Still float… Shut emlid studio down and restarted, fix. Maybe a little bug in the app?
Shaun,
Thanks for the update!
Hmm, I’d say that the Float solution may have been caused just by a typo in base coordinates. But now it’s hard to say for sure.
Anyway, if such an issue resumes, feel free to contact us. We’ll find a solution.
