GPS Signal Strength Problem

[NZmxer]

Hi

First post here. Myself and my father recently purchased a mavic air each. My drone seems to be mint however my father's drones GPS is dropping in and out constantly.

We can be flying in the same area and and I have a steady 15-16 sats locked and he has 6-12 dropping in and out of vision flying.

All apps and equipment is at the latest software/firmware version.

Any suggestions or does he just have a dud?

Appreciate any response

Cheers

Sounds like a hardware problem - probably the GPS antenna.

It might pay to refresh the firmware in your Dad's drone using DJI Assistant 2 on the pc

Thanks for your input guys.

I think you are right Sar. No change from the firmware flash through PC.

Although now when looking at IMU there is also a "data error" on ACC1. No matter what we do it wont clear.

He brought his through the DJI app. So I assume he brought it directly from DJI? Whats the best process to lodge a warranty claim?

Thanks again.

have a read here, seems a simple tap can cure a imu data error

[SOLVED!!!] - IMU ACC1 shows "Data Error" - AC has never suffered a crash or anything similar.

Hi, I was following the thread with great interest. I use MEMS sensors in my work and I suppose the IMU is just a type of MEMS accelerometer. Now personally I don’t have experience with an accelerometer but I do have experience with MEMS charged plates that exhibit stiction issues from time to...

A tap may solve the IMU accelerometer error but it won't fix the GPS issue. If this is the same AC that is showing GPS signal acquisition issues + an accelerometer data error; and if it is still in warranty and you can return it, I would suggest you exchange it. You shouldn't be having these many issues with a new AC - assuming it has not suffered a crash or a hard landing.

Agree with Doppler since you bought it from DJI arrange a to get a replacement

You can send their support an email

Thanks everyone for your help. Tried whacking it few times, no change however I do believe that is most likely the fix. But as Doppler mentions the GPS will still be an issue.

I will go through DJI support and keep the thread updated with how we go.

What's the general consensus with DJI support?

I'm Glad we have my drone that is fault free to compare against. I am extremely impressed with the accuracy and stability of the MA. Beautiful drone to fly.

If you can go through a local company it will be easier, DJI support is flakey at best as you'll be dealing with the China directly

I hate sending things to China as their mail system is so chaotic and tracking is poor

International Warranty

I have a relative from Canada who will be coming to visit me in the UK. My question to DJI is, if my relative purchases a DJI drone in Canada or USA (he lives on the border) and brings it to the UK. Will DJI in the UK honour any warranty ? Also has anybody gaot any experience of DJI...

Ask to send it to the DJI Australian Service Center in Melbourne instead of China

Hi Doppler

I notice your DJI Assistant 2 has a lot more options. Mine is version 1.2.5 and only has this

I used the old version of Assistant 2 (very 1.1.2) with the debug functionality enabled. Have a read here

Hey guys I've been helping lots of people set up Assistant 2 1.1.2 in debug mode on on their Windows computer which is a little more difficult than on a Mac and I have come up with a way to remove the most difficult part from the process. Attached is a link to download a package I've made which...

Thanks Doppler. Its seems I dont have permission to view that page?

You have to first know if the accelerometer is stuck on one axis; and if so which axis it is and what value it is stuck on. That determines where you tap the AC. But if you have the option to return/exchange the AC I strongly suggest you do so.

There is a setting in your account you have to tick inorder to access the software/hardware moding sub-forum. Go to your "Account details" page, see below:

 

[NZmxer]

Thanks again Doppler. Very interesting read that, cool to see what tweaks you can make.

I have setup the older version in debug mode and can see the X axis stuck at 16, similar to your experience.

But as you mention, this AC needs to go back for warranty claim.

I have created a repair job. And the address is an Australian one so fingers crossed it is a smooth process.

Will update as progress is made.

 

[Deleted member 94047]

Yeah, you did right by sending it for repair; thinkering with it yourself should always be a last resort. Good luck with the process!

I had also GPS problems on my 3 first flights with my new Mavic Air. I got up to a max of 11-12 satellites and 4 bars, but when I changed from photo to video mode the signal dropped. Even worse when I started a video recording it dropped to 7 satellites and 0 bars and changed to ATTI or OPTI mode. I returned id for warranty repair and got all my stuff back but the drone itself was exchanged with a new one. This one got a steady 5 bars and 15 - 17 satellites on the first flight. So yes, hardware faults can happen.

Thanks mate, good to know.

I created a repair job on the website and a free postal ticket was sent to me. I sent the AC but it must a very slow cheap service as it still hasn't arrived one week later. I should have just purchased my own courier bag and sent it over night!

Will keep updating the progress. Still no issues with my Mavic Air! My father is rather jealous haha

If you were a “good son” you would let your father fly yours until you received the replacement.?

Haha! No way, that's not how our family dynamics work, I will proceed to 'rub it in' that my Mavic is perfect until he recieved his replacement.
