[Paparazzi-devel] Sonar

Hi gauthier,
I understand that the sonar module would need some improvement. Did you or anyone already used it to take off or land with a rotorcraft?
Did you try to use the sonar only by reducing baro_sens to around zero?
Regards
Loic

Hello,

You should probably start by thoroughly looking through the
wiki<http://paparazzi.enac.fr/wiki/Main_Page>.
Paparazzi has components written in a number of languages, but the airborne
code is in C. To get started with the code, you will need to first install
the tools and get the code <http://paparazzi.enac.fr/wiki/Installation>.
You will have to explore the code to understand the system prior to writing
any additional code. You can also browse it online on
GitHub<https://github.com/paparazzi/paparazzi>
.

What kind of hardware do you have? Which main board?

Hope that helps get you started.

Thanks,
-Stephen Dwyer

Subject: [Paparazzi-devel] 10 m/s Minimum Speed in Simulator
Message-ID:
<CAEZoMYP8+=address@hidden>
Content-Type: text/plain; charset=ISO-8859-1

All,

I've been trying to lower my airspeed when flying since our aircraft
flies at less than 10 m/s. However, I've noticed that no matter where
I set the airspeed min/max set points, cruise speed, or anything to do
with speed, the simulator refuses to allow the aircraft to go below 10
m/s. Is this a hard limit imposed by the simulator or have people been
able to simulate fixed-wing flight below 10 m/s?

Best,
Chris

The normal sim has simplified linearized dynamics with hard coded minimum
speed. With zero throttle you can still climb by pulling the pitch up. Use
fdm sim for more realism.
