Hello, All Surveyer. I use M300RTK + Zenmuse L1 + D-RTK2 in RTK mode. 1) What is the GNSS update rate of the M300RTK aircraft? 2) What is the GNSS update rate of the D-RTK2 mode5? Thank you.

Hi, there. Please check the following details:
1) The GNSS update rate of the M300RTK aircraft is 5Hz.
2) The GNSS update rate of the D-RTK2 mode5 is 5Hz too.
Thank you for your support.

Thank you very much.
Can I continue with my question?

What does the red-framed number in "Zenmuse-L1-mission_Timestamp.MRK" represent?

Best regards.

Hi, there.
Sorry for the late reply.
The red-framed number in "Zenmuse-L1-mission_Timestamp.MRK" represents the standard deviation of the positioning results in the north, east, and up directions, indicating the relative precision of positioning in these three directions. Unit: m
Thank you.

Hello, DJI Natalia.

May I ask you another question?
I use M300RTK + Zenmuse L1 + D-RTK2 in RTK mode.

1) What is the speed accuracy (m/s)?

Thank you.

So is it useless to broadcast ntrip at 1Hz and log rinex from ppk at 1Hz?

I do everything in 1Hz, NTRIP networks are in 1Hz, It works perfectly.
The 5Hz is more to refine the precision of the position of the camera. But setting the RTCM to more than 1Hz is useless data flow. But you can do it if you like to have tons of RINEX files.

Hello, DJI Natalia.

May I ask you another question?

Hi, there.
May I confirm that you are asking about the speed of the drone? Or could you please tell me more details so that I know this problem better and do my best to help?
Thanks in advance.

Hi, there. May we have more details of your problem? Also, we have confirmed with the team,  just a kind reminder that the sampling frequency of M300 RTK is 5Hz. Hope this helps and if you have any more needs, please just let us know.

No problem for me.  I'm just trying to explain that on the side of the base station that records RINEX observations, it's useless to select 5Hz.

Hello, DJI Natalia.

Yes, about the speed accuracy of the drone with L1 misson flight.
Thank you.
