4 MAE 142 Body-Axis Velocity Vehicle velocity over the ground can also be expressed using the body-axis components. [ V N V E V D ] = T B2L [ u v w ] [ W N W E W D ] V N = velocity north V E = velocity east V D = velocity down u = surge v = sway w = heave W N = wind north W E = wind east W D = wind down [ V N V E V D ] = [ cos cos sin sin cos − cos
