Critical: Prearm: GPS and AHRS differ by 33m

Hello together,
I have an Octo Quad X Copter with Emlid Edge FC and a Reach M + module, tried today with the new Copter to fly and keep getting this error message.
What can this be and how can you eliminate the error?

Hi @rcdevil,

Could you post the hardware setup photos, please?

Hi Fred,

Did you manage to resolve this issue? Will you be able to post hardware setup photos?

[rcdevil (FRED)]

you mean a photo from my copter?

[rcdevil (FRED)]

Hello,
do you mean a photo of my copter or a photo of the settings of QGroundcontrol software?

[tatiana.andreeva]

Hi Fred,

I mean photos of your copter.

[rcdevil (FRED)]

hi Dmitriy, i´m working on it, actually no solution to fix or to localize this error.

[rcdevil (FRED)]

Hi Tatiana,
here are the photos.
Thank you.

Hi Fred,

Which material is used for antenna ground plane?

I’d also recommend placing the radio antenna and Wi-Fi module in different parts of the drone.

[rcdevil (FRED)]

the ground plane of the antenna is a round PCB plate with copper coating, with 70mm diameter.

Fred,

The copper coating should be on the side where the antenna is placed. Please make sure it’s so.
