"@Hugues, thank you, it is good to know that its best to mount the ceramic patch antenna onto the ground plane itself.
The repeated result with the 20×20cm 0,6mm copper plate is: 37 out of 216 patches are on average above 45 dB (C/N0):
The static…"
"Comment appended to the above test. The Neo 6M deviation doesn't improve at all. It still drifts 27 meters to the left and 25 meters to the right in this static position (relative to earth)."
"I was wondering what the improvement in signal strength (C/N0) would be when adding a (copper) ground plane to a Chinese GY-NEO6MV2 with a GPS-001 active GPS antenna.
For the test setup I ordered 19x19cm 0,6mm copper plate from Aduis. A standard…"

What was strange was that with the DroTek the signal strength of some satellites suddenly dropped for some ms. I am not sure what happened. Maybe a problem with the FTDI cable.
