Hello, i want to do an autopilot, my problem is ,i can't get the vertical speed.
i tried to see the acc.z from the ploter but it show me wrong value
please , how to get the vertical speed and how to integrate that to get postion

Helllo, i tried lot of techniques but i didn't suceed to get the distance using vertical speed, so how we do , to calculate the distance using vertical speed, if you can , write us a code to calcultae speed please

**** this forum, no answer we by your stuf with 150$ and no replay of our quanstion *******

We'll now you are getting kind of rude (censored your post). I'm not sure what you expect from a community but we do our best to answer questions as fast as we can. Count to that, that it is summer and vacation times.

To answer your original question:
You can integrate the acceleration to get speed but by integrating you are also adding up the bias so your measurement will get wrong pretty quickly (drift). Add to that vibrations caused bu the rotors and it is almost impossible to use that information over a longer time. The altitude hold algorithm uses the speed but relies on the barometer to correct the drift over time.

And I suggest you learn how to behave nicely in a community. That way people will be more willing to help you.

Droneman,

It can be frustrating when you don't get what you're looking for. It's likely that Caps Lock & insults won't get your questions answered any faster.

I've read some some your questions & I must admit that I don't understand what your are asking at times. Perhaps adding some description would get your questions answered more quickly.

yes so write me a code that calculate a distance, i want to see the distance in the ploter OK

what the fuck !!! the link doesn't work

The site was probably down. It works for me now, try it again.

Sorry we assumed that you would be able to find the contact email in the about page of our main website, like everyone else ever does. Are you even trying?
