How to limit to one satellite or one constellation?

GPS/GNSS
1

Is there a way to limit my module to use only one constellation and then only one satellite within that one constellation?

I have the SparkFun MicroMod GNSS Carrier Board (ZED-F9P) (GPS-17722).

Help, please.

You can use CFG-SIGNAL keys to change which signals it uses, but this tends to be rules based, and the primary core’s going to want to manage timing via GPS L1CA
There may be some masking and production test methods that limit things further, but that would be a discussion you’d need to have with your uBlox FAE, if you’re doing enough business to warrant that.

In uCenter Classic, look at View → Generation 9 Configuration View → GNSS Configuration

Hi clive1,

I need this for testing purposes, to troubleshoot other products.

Thanks for your reply. I will give it a try.
