Hi!
Could I request a couple of features in PX4?
I am currently developing code to allow my simulation code for a fixed-wing (or the vtol as seen in gz_standard_vtol in fixed-wing mode) to work in real life, but it requires alpha (the angle of attack), beta (the sideslip angle), and the airspeed.
I can see on the Ros 2 User Guide that there is a list of topics that can be used in PX4, but Airspeed, AirspeedValidated and AirspeedWind (which holds beta), are not available.
Requesting 3 Airspeed Topics over DDS
I understand that these topics are available on MAVSDK, but my testing has found that collecting all the data I need just from MAVSDK is (at best) 15 Hz. It might be easier with just one item, but as I understand it, it is impossible to run both MAVSDK commands and ROS 2 commands on PX4 at the same time (or at the very least, not supported).
These are the reasons I am hoping to request these 3 airspeed topics be supported on DDS.
If one had to choose which one of these topics to develop first, first and foremost would be AirspeedWind because it has both Airspeed and beta_innov.
Requesting New Topic with Alpha, also over DDS
Additionally, since the microcontroller is already working a Kalman Filter for beta, is it possible to simply apply the same idea to collect data for alpha?
I’m sure it would require adding an additional Airpseed sensor, but any support you could add toward these goals would be greatly appreciated.
