# Offboard_mission_control

I wanna know …
dronecore::Offboard::VelocityBodyYawspeed Struct Reference

#include: offboard.h

Type for velocity commands in body coordinates (forward, right, down and yaw angular rate).
Data Fields

float forward_m_s -

float right_m_s -

float down_m_s -

float yawspeed_deg_s -

what does *float down_m_s actually mean?

Is it the parameter to increase/decrease the current velocity?
or
Is it the parameter to move towards up/down?
plz try to answer as soon as possible…

It’s a floating-point number, in units of meters per second. Yawspeed is also a floating-point number, expressed in units of degrees per second.

HTH.

@parwaz1

Is it unclear from the docs?
