# Fixed Wing Lateral Setpoint message # Used by the fw_lateral_longitudinal_control module # At least one of course, airspeed_direction, or lateral_acceleration must be finite. uint32 MESSAGE_VERSION = 0 uint64 timestamp # time since system start (microseconds) float32 course # [rad] [-pi, pi] Course over ground setpoint, w.r.t. North. NAN if not controlled directly. float32 airspeed_direction # [rad] [-pi, pi] Angle projected to ground of desired airspeed vector, w.r.t. North. NAN if not controlled directly, used as feedforward if course setpoint is finite. float32 lateral_acceleration # [m/s^2] [FRD] Lateral acceleration setpoint. NAN if not controlled directly, used as feedforward if either course setpoint or airspeed_direction is finite.
