i wonder if someone is familiar with the pixhawk. I am currently using it together with the mavros package. The imu data i get are published with ~100Hz. Can someone tell me how i can increase the published sensor data of the pixhawk?

Thx for your help.

That depends on which firmware you use.


rosrun mavros mavsys rate --raw-sensors 10 --ext-status 10

(try different rates, also may be useful --all)


Edit extras.txt on SD, add this:

mavlink stream -d /dev/ttyACM0 -s ATTITUDE -r 200
mavlink stream -d /dev/ttyACM0 -s HIGHRES_IMU -r 200

(-d parameter depends on used port)

Thx. I had to increase the baudrate, but then it works.

I need to increase the IMU data on Ardupilot Stack hence I tried the comand ''' rosrun mavros mavsys rate --raw-sensors 500 --ext-status 500 ''' and even with ''' -a ''' but I get maximized change to 180. How can I remove the limitation on the maximum rate

by the way, I included the following in /etc/extras.txt on the sd card:

mavlink stream -d /dev/ttyACM0 -s ATTITUDE -r 100 mavlink stream -d /dev/ttyACM0 -s ATTITUDE_QUATERNION -r 100 mavlink stream -d /dev/ttyACM0 -s HIGHERS_IMU -r 100

but also nothing changed
