Hi gauthier,
I understand that the sonar module would need some improvement.
The module itself (measurements) is fine, it's the integration in
the filter (subsystems/ins.c) that is really bad.
Did you or anyone already used it to take off or land with a
rotorcraft?
I don't see why this would not work. I'm not sure of the behavior
when you fly out of range of the sonar...
Did you try to use the sonar only by reducing baro_sens to
around zero?
No. And I'm pretty sure it is not a good long term solution. There
is an attempt to make a vertical filter dedicated to agl somewhere.

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.
