Electronics and Running Gear: GPS Guided Rover Series

In this installment, I go into a bit more detail about the electronics package for my latest autonomous rover project. This is just an overview of the components, and I hope to provide more into how it all functions as a unit in future videos.
If you would like to see the first video in this series, where I cover the mechanical aspects of the chassis and drivetrain, you can find it here: • Six Wheel Drive, Four ...
A big part of the success of this rover comes from the excellent performance of the u-blox C94-M8P GPS RTK module. Although configuring these units for the first time was a challenge, I found valuable guidance on another RUclips channel, so if you want to learn a great deal more about the u-blox GPS RTK module, check this video out @iforce2d: • Neo-M8P RTK setup and ...

I'd like to know why you didn't consider the u-blox ZED F9P rather than the u-blox C94-M8P. This seems to be the way agopengps is headed and they are claiming much higher precision in routing.
I'm in Canada where RTK correction services are limited and expensive and I'm thinking about a lora base station, setting up auto mowing and field lining for 3 full size soccer fields, fields across the main fields, parking lot lining etc. The possibility of 1 cm accuracy is exciting. I’ve looked at commercial solutions like turf tank, traqnology and some open source auto mower solutions as well as agopengps and perhaps using dual gps on the rover rather than compass. I'm not sold on mission planner or the agopen software if I can just write some route software and control paint sprayer on off cycles.

Thanks for watching my video-
Sounds like an interesting project! Honestly I just used the same setup I saw another RUclipsr using because he had posted some incredibly in-depth tutorials on the setup.
I am not sure if the ZED F9P was available back when I first purchased my M8P RTK evaluation kit, but I have read up on it a bit since then. I am sure that if and when I ever build an entirely new RTK system, I will try to source a more recent hardware iteration.

To be more specific, I used the M8P evaluation kit because I wanted to avoid relying an an outside correction service- particularly one which would require a subscription and/or continuous Internet connection. With the M8P evaluation kit I am able to set up my own base station and do RTK (perhaps with slightly less accuracy) more or less autonomously, using only the signals from the GNSS constellation itself.
I suppose I could set up a similar system based upon the F9P, but I chose the M8P specifically because it included the radios on each unit allowing me to pass corrections from my own base station. From what I could find, the F9P evaluation module has no radios and relies on an Internet connection and a subscription service in order to function. I am really not very savvy on setting up data radios, so I chose the M8P kit because it was already packaged as such.
I suppose if I learn of a F9P evaluation kit with radio links similar to my M8P kit, I might look into that.

Hello would you provide complete details about it ??

Check the notes at the bottom of the video for a complete list of the individual components that went into the build. I have not published a schematic or the code just yet. I may cover those in a separate video if that would be helpful.
