I was using RTK on WSRN today to create a base line to start a job. My precision was down to 0.03 after about 2 minutes on both points. I set up on it and backsighted and my residuals were about 0.6' both vertical and horizontal. I made sure I was plumb and was using the correct glass, etc.
I then noticed that there were high Ionospheric condition this morning in the NWWA region. Even though I was not directly in that region and surveying at the time of the high ionospheric conditions were present I feel that this was why I was getting this result.
My main question is when there are solar storms, or bad ionospheric conditions, do your GPS residuals still read as being good or will they actually give you bad readings so that you would know right away.
Maybe there was something else going on, which is what I am trying to figure out. I set another gps point a little further out and when I set up on it the results weren't as bad but still concerning.
