[Paparazzi-devel] Trajectory pivoting in flight plan and wind direction/speed
Fri, 5 Nov 2010 19:51:40 -0000
Thank you all for the answers, after I spoke to Felix via IRC my sim session is
I have a couple of questions more, which are more general.
First one: My flight plan trajectories are defined and each of them include a
lot of points. I am looking for the way to pivot the trajectories including all
the points about one point, so that the first part of the trajectory is always
directed against the wind flow direction. Of course the wind direction will be
defined before each flight. So I need to change all trajectories as I described
before. Have anybody used something like this? Have you any ideas how to do it?
Second one: I need to define on some way the direction and speed of the wind in
the altitudes my flights carried out. As I can see GCS show me some data about
wind speed and direction. But I ask me how precise is it? And what methods will
be used to calculate it? I had an idea to calculate the wind speed and wind
direction using ground speed (GPS), truth airspeed (Airspeed sensor) and drift
distance, so as it was done in the "stone times" by the pilots. Another idea is
to use a balloon with an anemometer, but the models I could use together with a
balloon are quite expensive. Any ideas for how to measure the wind speed and
direction in different altitudes using paparazzi equipment? Or some alternative
I heard Martin had similar questions some days, Martin, didn`t you? Have you
found a solution for both of the questions above?
