At first, I assumed I had caused a problem when I relocated my docking station.
It took several attempts reinstalling both the Data Center and the Docking Station before the positioning finally resynched with my maps. That was not fun, especially since both locations were initially chosen specifically because they had good GPS signal, yet after the last couple of firmware updates they now show intermittent GPS signal quality.
Today, mid-mow, the map positioning drifted badly again. I noticed Yarbo doing a perimeter lap at an oblique angle away from the fence line instead of tracking along it. I manually drove it to the edge of the yard, but the app showed its position as being inside my living room.
I had to manually guide it back to the docking station to recharge. According to the map, it now believes it is sitting in my pool.
I also no longer see the option to correct map drift.
At this point, should I assume the next step is a hard restart and possibly reinstalling the positioning hardware again? Or is there another way to force a positioning/map correction that I’m missing?
EDIT: Found the map drift correction option after all. Didn’t fix anything.
Sounds like you might be having RTK antenna or cable issues. What do your diagnostics look like? Have you checked that your antennas are undamaged and tight as well as the cable connections inside? What does your DC CNR values look like?
Inspected the antennae when this happened last time and they’re physically intact and secure. Just now I tried to reinstall the Docking Station (in the same position) and it got the position resynched but not the direction. Yeah, it was pointing the wrong way.
I have now reinstalled and reinitialized the Data Center and Docking Station, and am waiting for things to stabilize. Core is still pointing the wrong way when I restore the map, even after rebooting it.
Right now from its perch on the Docking Station (not in my pool) the Core can see 23 satellites with 0.70 quality. I can’t see where the CNR for the Data Center is kept, but it was strong enough to permit reinstallation.
EDIT: There’s a phrase (among many) I give my medical residents when they’re puzzling over a patient’s labs or diagnostic imaging: “when in doubt, get off your ass and see the patient.” Going outside I discovered one of the Core’s RTK antenna mounts was indeed damaged. Antenna looks fine. Swapped to the short mounts.
When I looked through the Home Assistant HACS integration, it is showing a heading of 0.0’ in its current Docked-And-Charging position, whereas sitting on the Dock last night it showed a heading between 103-108’.
Remounting the antenna returned the heading to what it was reporting before.
Now I need to recalibrate the Docking Station positioning. Because I last tried to reinstall while the antenna was off, everything is now pointing in the other direction.
EDIT: After reinstall, we’re back in business. Imma order me some HA-609 antennas.
I ordered some off of AliExpress. They are not here yet, but they are now in the USA from china. I gave up on waiting for Yarbo. I only have an issue on the dock with a fabric cover on it, close to my house. But I was sick of waiting for GPS or driving it 3 feet to get GPS lock. I still don’t understand why Yarbo can’t just let rover drive 3 feet ahead? It has vision and sensors.
Glad you are back in business! Those are nice antennas. Get you some of the new flex mounts from Yarbo too. Those in combination with those antennas are solid and strong.
The flex mounts are available? I didn’t realize the “new” high antenna mount was, in fact, the flexible one. I ordered a replacement to have on hand when the snowdrifts return. I should probably order two, then…
I ordered the HA-609 off AliExpress. Hopefully getting them into Canada is less arduous.
