Navigation file

my rover is phantom4 Rtk . how i can get the nav file and timestamps files for Emlid studio

Hi Soultan,

Welcome to our community!

DJI Phantom 4 RTK should record a NAV file along with the MRK file during the flight. A MRK file is a timestamps file.

You can find out more about RTK drone data processing with Emlid Studio in this guide.

Hi kirill,

Thank you for your Attention.
I have the MRK but cant find Nav file.
maybe i can send what i find in the folder of image but i need for Email.


Please send us the folder to I’ll check it out.

By the way, you can also use the NAV file from the base. You can share a base raw data as well.

I send it

Hi Soultan,

I’ve received and checked the files, thank you!

Indeed, there’s no navigation file in the DJI folder. Probably it could happen because the log was too short: it lasted for one and half minutes. A navigation file includes ephemeris that the drone’s receiver hadn’t obtained yet for such a short term.

Base navigation files may be of help, but Leica records them in its proprietary format that isn’t accepted by Emlid Studio. If it’s possible to convert them into industry-standard formats shown in the screenshot below, you can use it. But such conversion is usually made in software like LGO or Leica Infinity.
