What was your setup for ntrip corrections?
Currently my setup is:
Ardusimple at base sending to rtk2go at 1hz and an ardusimple with Ntrip trough OpenGrade3D, with my phone as access point.
The fields I made so far where about 5km away and over time the vertical height was moving ± 4cm in heavy cloudy conditions, much better in stable sunny weather (±1 or 2 cm over the day).
Sometimes with a heavy cloud the blade was moving a couple of cm within seconds, then stable for several minutes.
That’s my feeling, maybe the atmospheric conditions have nothing to do with the precision.
I will built a setup with a base in the field. Maybe radio link or to rtk2go if I manage to connect it to Internet.
I think I remember reading potatofarmer say going to10hz will improve vertical accuracy ???
You need to adjust the zero on the go in any case, the RTK drifts by a few cm, more so in rain and clouds like @Pat said. Also the type of soil affects how the blade cuts into the soil, I noticed needing to have 1-3 cm more offset in very light soil compared to say heavy clay.
I’m not good at English, so it’s a sentence from a translation site.
I downloaded and ran AOG Survey, but there is no response.
The PC is CF-19, the OS is Win10, and the security software is Norton.
The latest version of AOG is installed on your PC.
If you have any problems, please let us know.

Hi, you can take a look at this software, if it can replace optisurface and ezigrade in opengrade 3d, it does not accept metric measures, thank you. Land Leveling Design using Engineering Field Tools - YouTube

Thank you for the introduction
However, is this software free software?
I checked the site, but couldn’t find it or didn’t specify it?

Have you got any personal experience with this one?
Hi, unfortunately I could not use it because it uses only imperial measures, I tried to convert the.agd files that are in this forum to UTM but with poor results, there are various programs that convert lat. and long, in UTM, but then the elevation stays in meters, I am optimistic because it seems to me done well, I hope that we find a way together.
If you download open grade v3.0 from Github/BrianT, will the “About” state it is v.1.3?
What I need to do is make a survey and have my cut line 9 feet down. My antenna is on the excavator boom and I’m installing a pitless adapter and water line.
Version 1.3 was giving me a problem.
Would I be best off downloading open grade 3D v 1.0.5 October 2020. Pat-I/Opengrade

Hi,
The OpenGrade3D is made for use with a 3D plan, if you want just to run a ditch at a given slope, maybe give this a shot: GitHub - Pat-I/OpenGrade: Grade display for ditching and leveling
That’s the latest development of the OpenGrade AFAIK, maybe @Pat can confirm?

For this you can use my OpenGrade v2.1.3 beta, it’s the one in @nut 's link. It’s @BrianTee_Admin 's with some more parameters like the ability to set a view distance under the ground.

Thanks Pat n Nut.
I retrieved Opengrade - Cuz Retail Sucks v2.1.3
Looks good… A humble observation is the duplication of buttons n menus that accomplish the same actions is a bit confusing for this noob.
I’ll take the 'puter out to the job and connect to the antenna. The issue that I had was I could survey but couldn’t make a cut line (at all). I am hoping to make this cut line a couple of meters below the lowest surveyed point. An ability to input that depth looks like it is possible after clicking the “finger” then entering a number in “move cut line Up/Down”.
I’ll be working down in this 3 meter hole today, safely…

Yeah to draw the cut line you have to use the “finger”
I use a mouse even in the tractor, so in the bottom right you can see distance from ground and precisely put the line.
When the cut line is completed you move the whole line up/down with the “move cut line up/down”
Here is the video from Brian drawing a cut line with his original OpenGrade, my version has more parameters but works the same way.
instead of mouse you can use the onscreen touchpad. thats what i do almost all the time

I cruised through the 328 posts and maybe missed it but wanted to know if grade control has an Ntrip client built into it like AOG. Does AGIO work with Grade control? Have a neighbor that wants to do some grading with an F9P as a receiver, thought he could just plug F9P into laptop via usb and just trying to order the right pieces to get Ntrip connections into the F9P.
Thanks
OpenGrade3D(for grading with a prescription map) has a built in Ntrip but OpenGrade(for standalone grading) not.
I use an F9P so for OpenGrade I use the Ardusimple bluetooth module on the receiver.
I use the Lefebure android-ntripclient.
See around post 164, there were some talking about RTK correction.
