I am working with a Ardupilot Mega using a U-Blox GPS but I am not able to get a lock and I need some advice on how to troubleshoot this. I have read that the first sat lock can take as much as 15 minutes with this GPS so I have left it outside for a while. My deck has a clear view of the southern sky so I dont think the outdoor conditions are the issue. The APM continues to flash the ABC lights which indicate no lock. I assumed the issue was a lost config so I downloaded the U-Center 6.01 software and had no trouble connecting to the GPS at 38400 but I cant get a lock while connected to this either. I am very new to this so I am sure its something simple but I cant think of anything else to try. Any advice would be greatly appreciated.
