The GPS setup has always been difficult. Now I have to setup a new one for the Raspberry Pi5 with Bookworm OS 64-bit, and the KStars/Ekos 64-bit.
After a lot of problems that's solved with help of friends I have it to work. A little problem still is that there is a bug in the GPSD ver 3.22, but it will be updated soon I hope. I have to restart the GPSD after every start of the system, then it work.
Here is my documentation of setup GPS:

Hope it helps someone because I found it difficult.
