I am new to pixhawk. I am using pixhawk 2.4.8 . I am getting pressure altitude from the pixhawk. I flew the drone in the open air at almost 5 to 6 meters height. Initially took off the drone with lidar then shift to barometer altitude but huge difference of reading between Baro Altitude and lidar. Also the Baro Altitude reading is fluctuating. Please let me know mainly how to make the pressure altitude reading stable or to has less possible variations ? Is there some parameter in the pixhawk to tweak ? Or do i need to make some kind of filter or is there any ready made solution available to get the stable baro altitude reading ?
