how can I correct inaccurate path during flight?
Hi,
I started mission that I did in the past but this time the path is off by 20-30 meters, and it going to crush into tree,
I had 10 satellite..
why it happening?
first what can I do to calibrate or correct the location error on ground, in advance,
and if there is no way, how can I correct the path when the drone is in the air and I've noticed the error?

I have never seen a discrepancy off by that much. Many possible reasons but it may be you changed something on the plan since it was last ran whether intentionally or not. Check the plan on the Web app and run the mission preview to see how it flies. If it looks good then download the KMZ file and run on Google Earth to get a much better view. Can you share the plan so someone can take a look at it ?

Hi, it happened on 2 different plans on the same area
Here the links:

If the issue is that the maps in the mission planner are not aligned with the real world, when you have two options:
Ok looks good.
But I saw that it isn’t available for me as a private user???
Only for expertise users?
I constantly have inaccurate issue with the app and I can’t use the tool to fix it?
If the feature doesn’t make the upgrade worth it to you, then you can use option 1.
Hi, the mission planned originally as on fly mission . And still when I operate the same mission it still discrepancy off.. so option 1 is no good
If the mission came from on the fly originally then I don’t think option 2 is going to solve your problem because it sounds like something else is going on with the drone’s gps accuracy. It sounds like you may need to do a few tests setting up other on the fly missions in a different area to see if you can reproduce it.
I would like to see option 2 treated as a basic safety improvement and an addition to all the plans, rather than just the growth and enterprise plans. Safety (flying accuracy) should be available for everyone. I would respectfully appeal this to Dronelink for reconsideration.
To be clear, if what is actually happening is GPS drift / inaccuracy, then this has been a problem with DJI drones (any other other drone using consumer GPS sensors) since the beginning. DJI’s hardware solution to this is RTK, and they have no software solution for it when running onboard waypoint missions. We implemented a software solution to this problem which is not perfect, and certainly not as good as RTK. It can be a little complicated to use effectively and safely (especially without any training), but the purpose was to enable professional users to get up close and personal when scanning infrustructure such as cell towers with consumer drones lacking RTK. This is one of the key differentiating features of Dronelink that none of our competitors offer, and it is one of the main reasons businesses choose to use Dronelink for inspections while being able to save the money on hardware (e.g. buying consumer drones vs enterprise with RTK). In the world where this software feature doesn’t exist (all of our competitors), the safety solution is to recognize the limitations fo the hardware (in this case the best-case accuracy of the GPS), and plan your mission accordingly - in other words, either fly at a higher altitude, or build in large safety buffers that account for the margin of error on the sensors. The vast majority of users that do not find this solution acceptable are the ones that need higher resolution images for inspections, which are businesses.
Thanks Jim. Informative information as usual. Can I therefore suggest you bring this safety feature into the Starter License as well for all business / professional users to benefit from? Hobbyists have the option of flying higher. Business users typically don't and must fly with inflexible mission parameters.
Let's maximize safety for all such users.
My appeal is sincere here.
Thanks,
Daniel
We are always open to suggestions and we do have a track record of changing which features are in which plans. Having said that, characterizing this as only safety feature is not really accurate. A better characterization would be this is a precision enhancing feature that can also be used to execute missions more safely if your accuracy requirements are such that you need to fly very close to things in order to achieve the precision you require. This feature is currently one of the main reasons people upgrade to Growth, and including it in one of the lower plans devalues the higher level plans, which can negatively impact revenue, which in turn negatively impacts our ability to create and maintain advanced features such as this.
