I install 2 GPS on my copter, GPS1: ublox m8n, GPS2: reach RTK ( I use another reach RTK as base)
During my flight, reach rtk sometimes have very large drift.
my copter did not move when reach rtk start to drift.
It may be unrelated, but I had a very large location glitch just yesterday. I turned on Beidou and Galileo and I got “displaced” about 4km from my base over the course of 1 minute. I was in the middle of a survey so I turned off the satellites and continued as was (20m baseline)
Thank you for reporting the issue, our team came up with a solution and it will be a part of one of the upcoming releases. We need to do some more tests, but it looks like we were able to fix it completely.
I still recommend to revise antenna placement on the drone as the signal does not look that great. Do you have a ground plane in place?
