Easily broken GPS 3DR GPS uBlox LEA-6 ?

Posted by Hugues on December 30, 2012 at 11:44am

Hello all,

I have just got my 3DR kit quad Arducopter with GPS 3DR GPS uBlox LEA-6.

During the assembly process that little GPS board fell a two or three times on my table from the height of the quad frame (I would say 10 to 20 cm high).

Then yesterday I connect the arducopter via USB , I see a workinh GPS in the mission planner, no problem (3 sats locks being inside which is not so bad).

But today I connect it again and absolutely no satlletite found : zero, nada, nohting. I tried to reboot the thing many times, still same problem.

I then inspected the ceramic antenna and notice a small crack on one corner of the ceramic square (the GPS antenna that is).

Is it possible that this would be the cause of the GPS not detecting satellites or is this another known problem ?

 

Thx for help

    Hello all,

    In the CLI window the LEA-6 responds and displays 0 Lat, 0 Long and 0 sats.

    So the cable is good.

    Yes the crack is welll inside the metalized area, si I suspect antenna is dead.

    Is there a way I good unsolder this antenna to solder a new one ? Where can i get such a ceramic antenna ?
