Does NAV WP effect Loiter?

Posted by Elvis on January 11, 2013 at 7:37am

I've read conflicting info on this. The Wiki says it does and Jason says it doesn't (I think)?

From AC2 tweaks / wiki http://code.google.com/p/arducopter/wiki/AC2_Tweaks

"In Loiter, my copter constantly overshoots: Try and increase your Nav_P term. You can also tune down your I terms because in some cases, the Nav_I or Loiter_I can causes overshoot. Making the Iterms 0 when in still wind is the best way to tune Nav_P."

 

Quote from Jason Short in  http://www.diydrones.com/forum/topics/acm-loiter-video

"NAV_WP_P is not used in Loiter mode."

 

Questions:

1. Are NAV_P and NAV_WP_P two different things?

2. I don't see NAV_P in 2.8.1, is it the same as NAV_WP that I do have in 2.8.1?

3. What does NAV_WP effect? MP says "Target" - is this "Target" a waypoint, RTL point, Loiter point, or all three?

Thanks

    Did you get any answers, I'm having the same question. My octo overshoots terribly in loiter and RTL, and I can't find anything in the PIDs that looks like NAV_P... No PIDs at all regarding Waypoint navigation (which RTL is?).

    I'm om 3.0.1.
