Hello, there.
I'm thinking of using RTK to fly a M600pro now.
But, since the sale of the genuine DJI D-RTK compatible with M600pro has ended, so I would like to use a third-party RTK module that is not genuine DJI.
Specifically, I am thinking of using an RTK module called C94-M8P manufactured by u-blox. The home page of the product is the following address.
https://www.u-blox.com/en/product/c94-m8p?lang=ja

As a configuration other than RTK, the drone is equipped with an onboard computer, and the onboard computer uses ROS to send commands to the flight controller.
And since C94-M8P is compatible with ROS environment (package: https://github.com/KumarRobotics/ublox), I would like to send RTK information to the flight controller through ROS.
However, I am in trouble because I do not know the system configuration when using C94-M8P.
On the hardware side, I don't know how to install the C94-M8P on an onboard computer and drone.
On the software side, I would like to use the RTK of the C94-M8P instead of the built-in GPS antenna to determine the latitude and longitude of the drone, but I don't know how to do it.


Has anyone ever done something similar?
Of course, other people are also welcome.
If anyone knows, please give me some advice.


Thank you;

Following as I need to do the same thing,
