I have been experiencing the same problem repeatedly in my last 6 flights. My inspire 1 starts to the flight normal, then slowly drifts away with the wind. I thought there is an issue with the GPS, but it recorded its location, I am posting it down below. Just to clear it, I was flying on P Mode. Besides, it is having trouble to land back to its departure position (there is a ~5 m deviation). I checked the sensor calibration, but it was ok. I am wondering what might be the problem causing this. Is there anyone who experienced the same issue?

Editor made a comment at one point to check for a Ublox module defect or crack - apparently if this ceramic is damaged it will affect GPS reception.
Hope this is some use.

Do you mean this (Amazon.com : DJI Inspire 1 Part 6 GPS Module : Camera & Photo) module might be cracked? It recorded the path during its drift tho, maybe the gps is ok and something else wrong? Some guys reported that, if the drone loose a satellite, it switches to Atti-mode and that might be the cause of the drift? However, in that case, it should notify me isn't it? There wasn't any warning message on the log...

Hey man, don't you think maybe the Inspire isn't the ideal drone for learning? I greatly advise you to put it back in the closet and try maybe starting from a Spark. I'm not trying to offend you, i'm saying the inspire wasnt built with you in mind and youre are going to lose or crash it. The spark hurts less when it happens though, and you'll get plenty of gps loses to understand what atti is and is not.

Dude, I understand you are trying to show us how much you know about drones, I am ok with it. However, what I really need is to troubleshoot the problem, so I do not experience the same thing again.

I used to fly with two people, one is flying and watching the AV, and the other operating the camera. If you are taking 360 photos for site surveying like me, a drifting drone does not make it easy. I can fly it in atti mode, in fact, what I really need is a steady still drone, that allow me to take 30 or more photos and stitch them for a complete 360.

If you want to show up yourself, please do so by showing the quality of your work. You are not the person who will tell me which drone should I fly and which.

A bit of harsh reality and respectfully differ from your

i respectfully differ with your rather harsh commentary and the inspire 1 can be an ideal training drone if one starts properly and doesn’t push the learning curve. And, imo is much more fun to fly. And, the added benefit of a reasonably good camera system, and a great entry level price as there are great inspire one bargains in the used marketplace.
Of course you are correct if throw caution to the wind and don’t learn the basics.

No, no, I'm sorry i offended you. I totally understand. as a self-employed IT manager that has a small consumer base but one that still requires the person that keeps them safe from the mind blowingly fast changing intrusion methodology, I get baffled every day how AI is taking care of more and more of the dark web, so I understand my customers expect a quality of service that reflects my monthly billing and totally trust me that the instruments I use to explain my much higher than average cost, are instruments that i know top to bottom, i can fully utilise them to serve individual needs and know how to control an unexpected situation because of unforeseen events. myself a new inspire pilot, just a few weeks old, coming straight from one hell of an adventure with a spark, and a fully utilized care refresh that gave me a big buffer to push it beyond anything advertised, I understand the potential of the Inspire and the many differences between an ideal training drone and one marketed as "a drone so advanced it can split the abilities to one operator for a complete control of the capture system and a pilot capale of pulling maneuvers that were only previously only available on larger platforms" (seen chasing sports cars, jetskis, boats full of people racing down rapids). But yeah, as one wise man said, "started from the bottom now were here" I'm sure your customers can trust their money is going into the pockets of a pilot that know his stuff and one of the dedicated flight modes and how it works and sometimes doesnt, and how to figure it out, without any risk to their property.

The point is, the learning curve is exactly when you push. You cant play safe then on the racetrack only to get hit by reality. You get that right? The spark is built for the new comers, DJI know this and made it as capable to compensate for user error as possible, there is no such thing with a 4000$ launch price drone...no matter how affordable it is, you can still pin the descnet joystick down and crash the crap out of it...good luck doing that with a spark.

Regarding your comment about wanting a stable drone that can stitch 30 photos for a pano:
I tried using an I 1 for panos with Litchi. I chose the mode where the camera does not turn, but the aircraft does (to avoid including landing gear legs). While shooting in columns every time the bird would rotate to shoot the next column, it would slide 3-4 feet. By the time I shot 8 columns, it had moved around 30’. The photos would not stitch. When I queried Litchi about this, they said the Inspire 1 uses a “first generation” DJI location system, and nothing could be improved from my experience.
My I 2, Mavic Pro and 2 are vastly superior in this regard. I have well over 100 hours on the I 1 and it is a good bird, but hates to (can hardly) fly with multiple axis input (right stick moving towards any corner). Good luck with your efforts.

Interesting answers here...

I regularly fly my Inspire 1, v2 a couple times a month. And, like you, occasionally she drifts. Sometimes I just let her go to see if she's going to stop drifting. 95% of the time she stops after about 10' or so. But occasionally, like a child with ADD, she'll act like she's lost interest in that location and and go into a pseudo "ATTI mode" (this, with 14 satellites acquired). If I continue flying (bring her back) without doing anything else, she starts behaving again. But it takes a minute. She doesn't exactly "snap to attention." She just sort of "wakes up." It gives her personality...<:^)

I regularly fly a P4P and it's funny - the difference in handling is night and day. I LOVE my Inspire 1 and will use her until I can no longer find batteries and props for her (hopefully no less than a decade from now). She's just a super-reliable platform that I can count on...but I digress... My point is that the Inspire 1 is "old tech" and as such, she doesn't "behave" as well as the more modern offerings.

Try this...

Let her drift to see if she finally stops drifting. It might take 50' before she stops. If she DOES eventually stop, then you're experiencing the same anomaly that I believe most Inspire 1 pilots experience. If she does NOT stop drifting, you may have other issues. Try snapping the PAF switch to F. And then back to P to see if that arrests the drifting.

Just curious...

Do you see this "bad behavior" every flight? Or just occasionally? If the latter, you're probably in the same boat I'm in. I wouldn't worry about it. My Inspire 1 has been the occasional "drifter" for years. I don't think anything is broken. I affectionately refer to her as the "barge in the sky."

Use your iPads "Screen Record" to record your flights so you can review them at home afterwards.

Good luck.

There are lots of words here that do not make sense to me. If I am flying a racing drone, I know that I have to control, attitude, yaw, pitch and whatever it is, depending on the settings that i am flying it. When I put my inspire 1 on P-Mode, it promises me to keep the drone steady still in the air.

I had other issues such as loosing attitude (it was going to crash on a truck if i didn't take the control on time and give more power to raise it to a safe height), battery issues, center frame issues and loss of camera view due to faulty pins with my inspire 1 in the air. If you check my flight record, it only drifted ~50m on a safe attitude, so the issue is not loosing it. I never crashed it, and I always fly cautiously, do not worry about that.

What concerns me to be clear is that, for all those problems I had previously, there was a warning message in the flight log. What is different here is that, the drone is drifting away with the wind, no warning messages, and it's happening continuously. It records the path that it travels so the first thing I thought is, maybe its switching to attimode as the other people reported. But there is no evidence that its doing so. I was shooting a video in my previous flight and i literally had to fight with the wind, and guess what, there was no warning as well in the flight log.

The one that I posted above was my test flight to try a new app for autonomous 360 however, even before I started the app, it started drifting away so I flew it back in attimode, and here I am asking what might be the problem. I have enough experience in the air, but this is unexpected and never happened before. I hope there are people somewhere there who can help me to clarify what might be issue causing this. Thanks,

I haven't read the other responses, but it's always a good idea to try the simple stuff first. I'd calibrate the IMU, even if the app is telling you the IMU doesn't require calibration.

Just throwing this out there...Did you happen to know the KP index when you were having these issues? Sometimes a high KP index can affect GPS systems.

I agree with Donnie, I calibrate the compass in every new location and quite frequently carefully recalibrate the IMU. If u happen to also operate a new MAVIC 2, u understand how incredibly sensitive this equipment can be to the slghtest electromagnetic magnetic disturbances. Alastir is correct although I have never seen KP greater than 4, I check it before every flight with Drone Buddy.

I didnt know about the Kp-Index, I found this video on youtube
. However, I couldnt find any kp-index reading for cyprus. So I am not quite sure whether its caused by magnetic resonance. Besides, we are closer to the aclinic line, it seems that people closer to the poles are most likely to experience problems with GPS.

I made 18 takeoffs in the weekend for surveying the coastline. I did the IMU and compass calibration at the beginning, and haven't experienced any problems at the first 10 flights. However, the last ones were not quite ok. The distance between the these 18 points were 8-10 km. I travelled by car without disassembling the drone. I am not sure whether its changing position or getting closer to the industrial zone and high voltage transmission lines that caused the slight drift in my last flights. It's not super bad, but I had to correct its position every time to get a proper image set.
I am going to do some experimentations today with and without calibration at the same exact place where I had issues to verify that, whether its the transmission line or the calibration. Thanks for the comments.

FlyingArchitect, I am having the same issue. Severe drifting. I had a local DJI dealer/repair shop check it out and said it was OK. I just don't believe it. I do not remember the Inspire behaving this way in the past. I used to be able to take panos (manually) and stitch with no issues. Today, I went out to do another test and the drift was considerable at around 25 meters. It EVENTUALLY stopped, but this is not normal.

Drone shop showed me a brand new I1 v2 and how it drifts as well. I did notice some drift (especially vertical), but the horizontal drift was not as severe as mine. I've done all the IMU/compass calibrations and they didn't do squat.

I am a photographer and have relied on this bird for twilight/sunset panos. I can no longer do them as the images will not even stitch, so it is going into the closet. I do have a Mavic 2 Pro, but it's low light imaging is too noisy even at ISO 100. That drone is pretty awesome and stable. I understand the tech is way beyond that of the I1. But, my Inspire never drifted this badly. Kp=2, 14 sats, 90F Wind 13mph gusts 13mph, Vis 9 miles, partly cloudy.

IF you find a solution that improves inflight stability, please let me know. I've read in places could be barometer, but that is mostly for vertical drift.

Drone shop said...it's an old drone, they drift, the MP2 has spoiled you. I've flown my I1 since 2015 and have not had such trouble.

Thanks.
