I was thinking of this definition from e.g. Esri for ArcGis.
GSA: GNSS DOP and active satellites.
I don’t need it now, it was just a thought to maybe implement it.
Would IT work with kverneland tellus pro monitor? Anyone tried?
I’m also wondering about GSA. I am trying to run a John Deere display/ rate controller setup, and John Deere requires GSA message at 5Hz. Is there any way to do this or any plan to make it available?

A lot of the information required for this sentence is not available. It may be possible to create a sentence using data that is available and fill in data for the missing information, such as satellite ID.
Why not configure the receiver to send GSA, and just forward it from AgIO to gpsout?
Yes, that is is good option. It requires editing agio.
For now I have it working with an rs232 converter directly off the f9p, but it would be nice to have it roll corrected! I don’t remember if GPS_out already does this, but I did find that John Deere displays require the GPS talker ID.
The latest release will send a blank GSA sentence.

Great work 
Just had time to try the latest release out. The blank GSA sentence appears to be working with a JD 2630. Thank you!
Amatron3 works GPGGA VTG and emtpy GSA sentence . 5hz on all.
Isomatch tellus also works GPGGA 5hz

Were you able to connect it, does the GPS work for mapping? Could you take some photos or sketches, I want to try it
We haven’t tried it in the field yet, but it worked on the yard. Just connect gpsOut to the John Deere display with the settings described here.
I have that manual, but could you upload a photo of how you did the wiring, and in GPS_out I can’t find the GSA.

I just realized I never replied to you. Here is the document describing how to add a serial port to your JD display.
If you download the latest version of GPS_out it will have an options tab. The GSA sentence is under that tab. However, upon connecting a rate controller to our JD monitor, I have found a problem. it appears that the JD display is losing signal every 5 seconds or so and causing the JD display to bring up a “loss of gps signal” message.
- EDIT
Apparently JD only accepts 6 decimal places of precision, and GPS out sends more than that which was causing the intermittent signal loss when sending nmea to the JD display. SK21 kindly wrote a version of GPS out that is limited to 6 decimal places and that seems to be working so far.
The version that is currently working with JD can be found at this branch on github.
