GPS hold doesn't work good #32

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. I have checked the GPS signal
2. magnetometer is defined correctly
3.

What is the expected output? What do you see instead?

It suppose to hold on one point (no wind at all)
The quad is not stable, It makes circuits around one point, keeps over shutting 
the point. 
where in the code can i control the parameter of the GPS position hold?

What version of the product are you using? On what operating system?

Please provide any additional information below.

I have this issue as well... I get oscillations around the hold point that get 
worse and worse. It flies great in stable mode, and is actually better at 
holding position on a calm day than the GPS hold is.

I'm going to try to mess with the GPS pids to see what I find. There isn't much 
info about tuning the GPS hold that I've been able to find.

This is the parameters which was good for my quad

Roll  P=0.020 I=.001 D=0.035

Hi 
I also have the same problem. I have a UBlox GPS. It flies great in stable 
mode. If i activate GPS hold .... oo my god  :-) I drifts all milisecounds from 
one to another point, very scary.

So this PID is for what ? I dont have a parameter for GPS PID`s.

Please let me know 

Thx

Tino

Hi Tino

PID =  http://en.wikipedia.org/wiki/PID_controller

you got the PID setting on the "configaretor"

http://code.google.com/p/arducopter/downloads/detail?name=Configurator.zip&can=2
&q=

There you can set the PID parameters

as shown in the photo i have attached
