I must admit, that I got a little confused by the tone after submitting my problem in this forum. I hade to read what I wrote several times to understand what I did to get this tone. My conclusion was I critizised SPARK. That’s what I think made to many say ”100% pilot error”.
I like to test new technology and very often do. And therefore I also know that new technology almost come with flaws and unexpected behavior. I AM SUPERIMPRESSED BY ALL TECHNOLOGY THAT ARE BUILT IN IN ONE OF THE CHEAPEST DJI DRONES!
Thomas!
This is the best question I read since the first post!
Yes, I think this is a technical problem that can be solved with firmware programming, but for some reason the DJI does not hurt to solve it.
There may be economic reasons, for example: Mavic Air came out that could bring more revenue and concentrate on it.
Somewhere I read it would not be possible to get Spark, they will not produce it anymore.
It may be cheaper to make up for lost Sparks than solving the problem.
The error:
- is there a bug for a compass (weak, cheap construction?)
- The system will then switch from GPS mode to ATTI mode (despite 20 satellites)
(At that time, it would not have been a disaster, because with the small compass and little practice, the drone would turn it back home)
- But unfortunately (and this is really fatal) the connection to the remote control is terminated
(In GPS mode, this would not be a problem because the RTH would be activated and coming home) -this is together, a deadly combination
Engineers plan and programmers write down control processes and what happens if something happens.
That's why it's unclear how and why it says about the stable GPS control due to the compass error and why disconnection is interrupted?
I understand that in many cases the compass is important because it knows where the front is and which engines to control it to start in the desired (GPS) position but ...
in the case of a compass error, you could just come home with a GPS signal: you could find your own direction without the compass, just move forward (in the direction of the camera) and then calculate the new GPS position to calculate where the front is at and where to turn home point. Repeat this way to come home smoothly.
Instead, it will be a catastrophic fall of the scenes of a mismatch of a (small) problem. This is a factory failure!
I really like Spark, a brilliant gadget but I do not trust her as much as when I bought it.
You would have a car whose brakes are generally good, but read about 10 cases when the brake is defective and the owner died ...?
You never know when you're coming ...
And what has so far not been said: what happens if this error occurs over a populated area and from a high altitude drone fall into the people?
DJI has to give a dense response to why this is happening!
