Posted two pictures below. I started getting an Anomalie error this morning in reference to Multilateration. Says location is incorrect or my pi is running out of CPU. Ive even updated my location again. (It is within 100 yards) Any ideas? I have rebooted the pi etc.

I've checked all the stats of my pi and everything is running well.

Check your USB connections & cabling, you're probably dropping data somewhere on the USB bus.
Your timing data is marginal, there is enough instability over time that the server never has much trust in your data.
You need a solid 30 minutes of stable data to get out of that state and that doesn't happen.

snapshot at the moment (many of those pairings have only been stable for a couple of minutes)
