GPS problem pixhawk

Im using ublox neo m8n gps module for my pixhawk, it lights solid red and i made calibrations. But when i open Mission Planner it says GPS: No fix. im not sure is my gps working. could you check it

Hi, are you testing this outside? Without sky usually it won’t work.

Most GPS units have a second pulse led. Once they acquire 3D fix, they start pulsing a led every second. And it’s a different colour then the “power present” led.
Also, depending on what’s actually inside, and your view of a clear sky, when powered on after a long time, may take long minutes to find a fix.
