thanks for the response. This is my 4th or 5th core. I have been using this one since December. I have the snowblower. No issues with GPS during the winter. Now that it’s spring, I’ve rebooted the core and I have had strong signal, 2 minutes later it’s disconnected
Well hopefully @Yarbo-Forum can take a look at your ticket and get someone to figure out what is going on.
Hi there, I’m sorry to hear about the GPS issue. I’ve checked your support ticket and asked our team to investigate further. We appreciate your patience while we work to resolve this for you.
I’m happy to report that I got my GPS problem fixed. I reinstalled the data center and that was it. I had checked all the cable connections already a week ago when the problem started so with the correct instructions I had the fix implemented in less then 5 minutes.
I will copy/paste the instructions I received from Yarbo technicians and hopefully it will someday be useful for others with similar problem:
Please replug all the cables connected to the PoE adapter, which is linked to the Data Center.
Bring your Yarbo Core as close to the Data Center as possible.
Open the Yarbo application and navigate to Settings > Data Center.
Proceed to reinstall the Data Center and reinitialize the connection with the Core.
Additionally, please ensure that the HaLow antennas on both the Core and the Data Center are properly installed and securely connected.
Thanks for the update and glad it is resolved. The FALSE on the rover mode in diagnostics was a key indicator there (plus no GNGGA on the DC and connection 0), but that can be a red herring as it will say that if the app isn’t communicating with the core too.
We tried that and it did not fix my issue. I’m hoping this new firmware will fix my issue. The FSE said they are going to send me another core, I have not received any confirmation though of tracking. I was hoping the new firmware that was just released would eliminate the core exchange. It definitely seems like a software issue in my opinion.
When you reinstalled the DC, did you have to remap everything?
Save your map under settings, previous maps. It should save local to the core and also to the cloud. Verify the date and map on the cloud is all current when saved. Then you can reinstall the DC which WILL wipe the maps and any locally saved ones. However, you can restore it from the cloud afterwards. Be sure everything is aligned properly, else initiate a map drift correction and you should be good. Also note that a map restore will reset all areas, pathways, schedules, and work plans to defaults. You will have to set all of that again.
I was “lucky” enough to have been delivered another new core just after winter season. So I didn’t really care about saving winter map. Had the plan to map new summer mowing map anyway. Have been remodeling the yard so new map was necessary.
I wasn’t hearing back from support so I bought a new Antenna from a reseller and it fixed my issue. They just shipped me a replacement core. I didn’t have a chance to update the ticket in time.
Reach out to support and they may be able to recall the shipment. If you drop your ticket number here, perhaps @Yarbo-Forum can relay that to the logistics team. You can also refuse the shipment when it arrives.

Glad to hear the replacement antenna solved the issue. I’ve already shared your update with the Field Service Engineer responsible for your case.
Thank you for the update, and we really appreciate you keeping us informed.
Anyone have a part number and source for third party replacement RTK antennas? I’d like to get a few on hand as they don’t seem to last more than a couple weeks.
Thanks, Bryan. Are these exact replicas or similar, maybe even better quality than what Yarbo ships? 
These are ones that they were testing. They are not an exact replica for the stock ones. They are higher gain and work great so far.
