Same feature request here:

> Hello there, I am living on a mountainside with an area about 600-800m^2. I have 3 trees there on the side. I’ve teached my yarbo to mow this area and marked every tree as a no-go-area. The result is more or less okay, but after all there are 3-4 lines of gras, which my yarbo missed mowing. Meaning a line about 5-6m long and 10-20cm wide. This missed lines are not under the trees, so I wonder what caused my yarbo to miss this lines. There seems to be no logic yet, to do a GPS-less navigation, m…

There is currently one problem:  
When loosing GPS especially directly under a tree, I had the situation that yarbo waits forever for a valid GPS signal. But this will end in a dead end cause of the tree (no GPS). So I had to manually move yarbo away from tree and start mowing again.

A currently workaround: I added a larger no go area around tree to avoid GPS dead end.
