DJI phantom 4 RTK

[trkim117]

Hi!
Today is the last day of 2019.
I wonder someone who has used DJI phantom 4 RTK for UAV processing toolbox or cBathy
can give some tips for the questions below.

1)Are there any accuracy differences when you use network RTK or D-RTK2 GNSS mobile station provided by DJI?

2)Have you ever replaced the D-RTK2 GNSS mobile station to other GPS station such as PROMARK
without any problems using P4-RTK?

3)Do you think it is worth to replace the P4 to P4-RTK for cBathy?

Thank you for your time and Happy New Year!

Best wishes,
KIM
