I am ready to invest some time/money in project besides my initial donation.
However, I somehow do not believe  multirotor aircraft will be able to hover very steady (/in wind) without an barometric altimeter.
What about the "Pro" version, anyone know how much "better" it'll be /and when the hardware is out ?

the pro has a barometric altimeter afaik

I don't know which chip the new PRO INS uses, but the beta board of pro already had a barometric altimeter which allowed altitude control in the order of magnitude of tens of centimeters (ca 0.2 m )

You're absolutely right, you will need some kind of altitude sensor for steady hovering in the wind. The Pro version will have better sensors, more sensors, and better algorithms, so you can expect some incremental improvements in overall flight ability. It won't be magical, mostly because the CC is already so good there's not much room left for improvement. You can expect that most of what the Pro will do is give additional possibilities, such as autonomous hovering and navigation. That's where the "much better" will really be felt and seen.

hi guys, i´m new here and i would like to know more about this project, is there any GPS, Sonar, magnetometer sensors already implemented for this project ???

thanks in advance

[Kenn Sebesta]

Yes, the CopterControl has a firmware branch where this is implemented.

thanks for reply, i´ve installed the GSC software already and i could noticed that, but i haven´t had a close look at the board yet, are these sensors/GPS components already available for sale ?

thanks

[Kenn Sebesta]

Not per se. You could check out http://forums.openpi...urrent-monitor/ to see the branch that implements an analog sensor package, which in the end is effectively what the mag/altimeter/sonar is.

thanks Kenn, so... now, where can i order the board in Europe, looks like there is none available at the webshop ???

Just to be sure we understand each other, I'm not talking about any ability to use the barometric sensor in the vehicle. That doesn't have any kind of support, AFAIK. Rather, what I mean is that the linked to page shows how Scott used an external ADC to send sensor information to the ground. If this is what you're looking for, than you could buy the ADC mentioned in the other posts, and then attach it to a baro sensor.

yes i understood your point, my problem now, is starting from the begining....first is to purchase a new Open Pilot controller board and then i´ll try the rest !

thanks
