Weird GPS problems

Posted by Anton Khrapov on January 3, 2015 at 4:45am

Hi all,

I'm experiencing some weird problem with GPS.

I have used my APM on a plane with no problems. GPS (MTK one, from Adafruit) is hard-wired (soldered to the board directly).

Now I want to use this APM with GPS on my hexa. Nothing was changed but firmware on APM board. It sits next to my laptop with only GPS and RX connected. Power is supplied from USB. The problem is, there is no GPS lock AT ALL. If I flash arduplane back, GPS comes back ok. Arducopter - no GPS.

Any idea on what that might be?

      Thanks for the reply.
      1. Yes, both apm planner and mission planner are up to date. I tried them both. I'm flashing 3.2 version of apm.
      2. Nope. Just APM, GPS and rx are interconnected and lying on laptop.
      3. I tried both indoors and outdoors with exact same result. The only difference is firmware. Arduplane sees gps, arducopter does not. No blue light, no gps lock in planner. Gps itself blinks with its own led that 3d lock is there, but APM does not see it.

      Could you please specify the model of the GPS or better, paste a link to the adafruit page? Thanks
