GPS not working

Posted by Luc van Helfteren on June 20, 2012 at 1:21pm

I have an APM 2 and the GPS functionality is not working at all. The blue 3d fix light never comes on, solid or blinking.

When I run gps in test from the CLI i get G! G! G!

The board is brand new and has never been flown, does anyone have any suggestions?

    Hi Luc

    I had a simalar problem to you with the APM 2 it was to do with the 6 pins not soldering the connectors properly on the top GPS board (my fault), after I had re-done the connectors all worked fine.
