How do I obtain the pressure sensor reading using MavLink ?
I have tried MAVLINK_MSG_ID_SCALED_PRESSURE"but the values don’t make any sense.
pressDiff = -10.7hPa
absPress = 508.1hPA
I haven’t looked at RAW_PRESSURE yet but is that message I should be using.
I am building a towed system (i.e. a sidescan, ROV without thrusters) as a cheap system for collecting imagery over reefs for mapping using 3D reconstruction. I feed a calculated position (as a psuedo USBL position) for the sub using a fixed layback but would like to feed an accurate depth for the sub from the pressure sensor.
