I found out what was wrong.
The external antennas from my two GPS modules were both broken.
After a long time, the module found satellites with the internal antenna.

Hello everybody,

I try to use the GPS module with my M5CORE Gray.

I tried the example for the GPS module, but it didn't seem to receive any satellites. I have also put the device outside for a long time, but still no signal.
The only thing that works is the time.
I use the external antenna.
Here is the output from the GPS module.

*$GNRMC,153551.00,V,,,,,,,190220,,,N*6D
$GNVTG,,,,,,,,,N*2E
$GNGGA,153551.00,,,,,0,00,99.99,,,,,,*7E
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GPGSV,1,1,00*79
$GLGSV,1,1,00*65
$GNGLL,,,,,153551.00,V,N*52*

Does anyone of you have an idea?

Thank you very much and best regards
Simon
