Navio2 integrated GPS problems

Hello guys!

Sorry it’s taken me so long to reply.

First off, you can attach it using a extremely cheap USB-Serial converter like CP2102 saving your hardware UART port. Just plug into USB and you’re almost good to go (you need to pass /dev/ttyUSB0 as -E switch to ArduPilot in /etc/default/arducopter).

Secondly, is it possible that this case might be also of use?

The only thing that could cause issues like that might be a faulty antenna connector or a faulty antenna.

Could you please try to make a little pressure on the antenna connector (or even rotate a little) whilst testing outdoors?
