Drone Data Processing - Float with CORS Data

I am attempting to use CORS Rinex data in conjuction with our UAV log file, using Emlid Studio 1.1.

The UAV is a M300 running their latest firmware.

While in-flight, we received a notification on our controller when the RTK symbol on our DJI smart controller changed from a green color to an orange color and with a “-” symbol. As a result, I wanted to process using PPK to compare the camera locations to verify the RTK data.

When I process within Emlid Studio, all the results are in float. In addition, I have been receiving a “Something Went Wrong” error also. I have forwarded a technical report to Emlid for their review.


I have attempted two different CORS locations. Each is approximately 30km from the site location. A screenshot of the satellite signals

The settings within Emlid are provided below.

Being a new user, I am not permitted to upload either the .obs file or the .nav file.

Try reprocessing the solution with GLONASS turned off. Sometimes this is helpful if one of the GLONASS satellites is throwing off the solution. For your obs and NAV files, you can upload them to google drive or weTransfer and post the link here.

Hi @reynolds8126,

Welcome to our forum!

I believe we’ll figure it out, but I’d check your files to reproduce this issue. If you’re not permitted to upload files here, please write us to support@emild.com. I need the following ones:

  • Observation files from base and drone
  • Navigation files from base and drone
  • MRK file from the drone
