I am new here and I would like to fly crazeflie 2.1 with LPS. Can anyone tell me what ROS packages are available? I found whoenig's crazyflie_ros
(, but it seems it does not support LPS. Thanks in advance.

Hi, you do not need LPS support in ROS since with LPS you get the position in the Crazyflie: as soon as LPS is setup, you can send position setpoint and get position estimate from the Crazyflie without needing special support on the client side. This is in contrast to motion capture systems that do require support on the client side because they measure the position outside and this position measurement then has to be send by the client to the Crazyflie.

I added a short note recently to the bitcraze/lps-ros project explaining a bit the procedure to get going with LPS and ROS:

Thanks a lot for your reply.
Could you also tell me how to get position estimate from the Crazyflie?
I would like to get position data in real-time using Python or ROS. Thanks
