Velocity transformation IJK->SEZ IJK is an inertial reference frame SEZ is a non-inertial reference frame either way, IJK is moving. Vx, Vy, and Vz (from telemetry are given in terms of i j k coordinates) Before applying the rotation matnces, need to express Vx, Vy, Vz in the non-inertial frame(although they will still be in i,j,k coordinates-> the rotation matnces will get the min s,e,z,coords) vel of object = Vel of object + true vel of pt in reltofixed relto moving frame frame monng frame where object is (Vx,Vy,Vz) (Vi,Vj,Vk) located (wxr) Wo=ano w=(0,0,Wo) Velocity r=(x,y,z) of earth [up arrow] from telemetry wxr=(0,0,Wo)x(x,y,z) = -WoYX+WoXY [up arrow] subtract these from Vx and Vy components from telemetry (Vi,Vy,Vk)=(Vx+WoY,Vy-WoXVz) [up arrow] Apply rotation matrices to SEE PG. 87 "FUN.
