None of your current hardware will be much use I'm afraid.
You need the autopilot unit itself which is called a Tiny. This goes in
You can't stabilise a UAV via the ground, there is too much latency.
The paparazzi board (Tiny) does all the work, the ground station simply
displays what is going on and allows changing high level flight
parameters (current waypoint etc).
If this is your first UAV project, forget the gyro - Paparazzi
traditionally uses infra-red level sensors, which are described on the
Have any of you got experience with model aircraft? You will need
someone who is competent at flying model aircraft. Your Twinstar should
be fine. You almost certainly do not want to build your own Tiny board
- I would highly recommend purchasing from one of the suppliers, listed
on the wiki.
An example of everything you need is here (I'm not promoting this
particular supplier, they are just the only one I'm currently aware of
with a photo of all the stuff you need!):
Also, read getting started on the wiki:
I would recommend maybe reading through the wiki a couple of times, and
then trying to run a simulation as described in the getting started
section just to see how everything fits together.
All that said, welcome to the mailing list and to the Paparazzi

I'm an engineering student from Lyon who got currently involved in a
project of building an UAV. We took over the project from another
which already put some work in this. Right now, some hardware was
- a microcontroller (PIC16F876A, 20Mhz)
- a receiver/transmitter set (ARM-U8, frequence 868Mhz)
- a GPS chip (EM406A)
- a quartz (20Mhz)
- a gyroscope (IDG 500Dual)
- a batterie
- some cables
(As we think that the receiver/transmitter doesn't work with Paparazzi
(?), we are probably going to change them.)
Our goal is to buy a Twinstar II, build the necessairy card, wire
everything together and than control the drone from the ground via
Now as I have described the setting, do you guys think this is
I'm not quite sure about the true function and work done by Paparazzi;
am I correct when I say:
* Paparazzi does all the aerodynamics calculation
* It than sends the current speed and direction orders to the plane
* The card on the plane needs to interpretate the orders and do the
actual adjustments of control signals / power levels
* The plane itself sends back GPS / gyroscop signals to Paparazzi
So our main work would come down to the above described interpretation
of orders. Is our microcontroller sufficient for this?
I'm sorry for this quite lengthly explanation, but I tried to keep it
short anyways :-). When reading the Paparazzi Wiki, talking to the old
group and our tutor, we got a lot of different infos about Paparazzi's
mode of operation + capabilities, so we thought it would be the best to
ask you guys directly.
