GPS stopped to work

Hello… can I damage GPS (Here) which is connected to the Cube while the Cube is only connected on USB cable to PC but NO power supply? Till now GPS worked well, but now doesn’t. There is red light blinking on GPS, Ardupilot is reporting bad GPS health (No Fix), there is zero satelites found.

No. Are you getting gps fix when you test it outside? Are the compasses working?

Hi, yes gps fix. I was doing it indoor but near window but still no satelites. I will try outside.
