I evereybody, new here. Got a big issue about GPS that I'cant manage to solve...
Ok so, different bn 180 GPS modules on different rigs are consistently giving me very inaccurate positioning. RTH and GPS rescue work as they should, but I can't trust coordinates at all.
Yesterday I had 16 satellites at arming point, checked accuracy by putting lat and long in Google Maps... Showed a position which is almost 9 km away from the real one...
Any suggestioni?
Thanks!

If you have a ftdi adapter connect it to your pc and install u-center to check your position. That should rule out if it is a hardware problem.

Thank you, don't have the adapter, guess I'm gonna get myself one. However I have the same problem in 3 different bn 180... So it's unlikely to be and hardware problem

Yes it's unlikely. I have two Bn-180 and they work fine but there are some feedbacks on the web of bad batches. I hope that's not your case. Try to power up only the fc and gps unit, no vtx or receiver and check if it yelds the same results.

Ok, thanks, I'll test this out
