I don’t understand why I can’t Map (says weak GPS Signal) but when I check the Rover diagnostics there are 20+ sats???

There’s a lot to what Yarbo calls GPS. Total satellites isn’t the only requirement. If you can post a screenshot of your diagnostics, we can take a look and see what the issue might be. Include the RTK, Status, Data Center, and HaLow sections. Also under RTK there is a yellow details, click that and connect to your DC. Provide a screenshot of the CNR map too. You can blur out any GNGGA information, as this is your GPS coordinates.
So everything looks good here except for your quality. 0.5 or higher is what is needed for good GPS. Your DC CNR values look great. All other stats look great. Your L2 satellites are a little low, but still over 10. Was this taken in the area you are trying to map? Is the area obstructed at all? Do you ever see a green or good GPS signal? If you do, you can go into settings, Yarbo Labs, and adjust the mapping threshold up a little. Don’t go too crazy with it. Do 10-20ft extra at most. It might help get you through mapping. The other thing you could try if that isn’t working is disabling PPVS and see if that lets you get it mapped. However, make sure you monitor it closely the first few runs to make sure it isn’t deviating due to poor GPS.

Hi there! You can try following Bryan’s suggestion and adjust the PPVS setting to see if it helps with the mapping issue. Hopefully this improves the GPS performance, and feel free to reach out if you continue to have any trouble.

These stats were taken at the charging pad. It varies from poor to green. The data center has un obstructed sky view. The pad and area that I was finally able to map is shrouded in Douglas Fir trees.
I thought the the data center’s unobstructed view would handle the areas where gps signal for the rover was poor.
The DC is just your fixed reference point for essentially triangulating the rovers location down to cm level accuracy. BOTH the rover and DC have to see the same satellites for this to work. They don’t need to see each other or anything. Just a decent number of the same satellites. They are working on some solutions to help work for longer periods of time without GPS signal and hope to eventually flip it so that GPS/RTK isn’t the primary means of navigation. PPVS is their name for it. Currently it uses dead reckoning. VIO and VSLAM are on the roadmap.
If you can post some screenshots of your diagnostics in a trouble spot we can see how far off you are and maybe find some work arounds. Also if you don’t mind sharing some pictures of the area that you’re trying to map.

Thank you. That is helpful information. I will post tomorrow.
