Absolute Geolocation Variance Error

#1

I just ran Step 1 and Step 2 on my drone flight. I’m concerned about the Absolute Geolocation Variance report. I attached a copy of the report.

  1. What are the acceptable parameters I should see?
  2. How do I fix the issue?

Hi, Are you using GCPs? The high vertical RMS error for absolute geolocation variance is expected if you have GCPs as it reflects the difference between the initial vertical coordinates (wrongly measured by the drone GPS) and the computed vertical coordinates (accurate corrected with GCPs).
