"The real reason is when use rangefinder : target_climb_rate is changed by get_surface_tracking_climb_rate
target_climb_rate = get_surface_tracking_climb_rate(target_climb_rate, pos_control->get_alt_target(), G_Dt);"
target_climb_rate = get_surface_tracking_climb_rate(target_climb_rate, pos_control->get_alt_target(), G_Dt);"
"I found the reason maybe this:
_vel_desired.z = constrain_float(climb_rate_cms, _vel_desired.z-vel_change_limit, _vel_desired.z+vel_change_limit);
_vel_desired.z !=climb_rate_cms because is chaged by this
I printf the result when climb_rate_cms =0.0…"

"I test here in loiter code :pos_control.set_alt_target_from_climb_rate_ff(target_climb_rate, G_Dt, false);
I printf:target_climb_rate _vel_desired.z when target_climb_rate =0.0,but _vel_desired.z != 0.0!!!!!"
I printf:target_climb_rate _vel_desired.z when target_climb_rate =0.0,but _vel_desired.z != 0.0!!!!!"
in update_throttle_hover() function:when I'm in loiter and leave all stick in mid ,I found I can not learn thr hover,I found the reason is if (!is_zero(pos_control->get_desired_velocity().z)) { return;…
Rencently I use a Chinese GPS board it has two Antennas,so it can out put for yaw data,since use we usually use compass for yaw I want use the GPS output heading instead of it,my method is change here…
