Hello all ...
I've just recently been having issues with my GPS not working. I noticed it when I was trying to get my quad to RTL and it didn't want to listen.
When I run the test from the terminal on the gps it gives me ublox ok, but #sats is always zero. I've tried moving the GPS module around on the frame and moved the power module away, but doesn't seem to help. On the GPS I see the red light is solid, but nothing from the blue. It's not blinking. I've seen it blink, but then it seems like it stops all together. The APM continues to alternate blinking red and blue, but the blue is never solid.
Running the Arducopter 2.8.1 firmware
Mission Planner software 1.2.29
If anyone has any suggestions, I would appreciate the input. I think I may have a bum GPS...
Thank you,
Lars

I believe this is happening as a result of my F550 circular power distribution board. It is EMI
If i connect via usb and get a lock, all is good until I plug in my battery, i instantly loose my GPS lock!
Guys, i am having huge issues with the uBlox GPS modules. Ive had 2 APMs with 2 different GPS modules and both times, the same results.
I am getting a GPS lock on USB ONLY. No lock whatsoever when powering off a 3S 6000mah lipo. Ive checked the voltage under load on both battery and USB and there is .10 of a volt difference. I have tried powering the GPS unit using a regulated dedicated BEC with no luck! As soon as i plug in USB, a lock in under 60 seconds, on battery it just flashes for 30 mins + with satcount of 0
So, i pulled out all the ESCs from the APM to make sure there was no noise being supplied by one of the ESCs BECs. Used my regulated BEC to power the APM and same thing.
No matter what i do i am unable to get a lock on battery! Very odd and frustrating problem!
Any help much appreciated!
Check your GPS cable and connectors (sometimes one of those little pins can get bent)
