wasn't going to have any velocities in there , and
very seldom did.
But we never failed t o have fairly
sizeable ones , like fa and fo fps, in another axis
and I'm not quite sure how it got therE·.
I guess
the spacecraft is extremely sensitive . If you ' re
going to make pr ecise burns, you
I ve gotta really burn
precisely and i f you want to take out the errors , take
out the address 81 and 82 errors so that you don ' t
introduce anything else.
During the difficult ren­
dezvous maneuvers, you have to plan on more
f uel usage because you're going to have to take it out
with the up- down thrusters .

I think what you ' re going to have to do is stop
short of burning off all your forward or aft velocity,
particularly the forward velocity, and then use the
canted thrusters to burn off the right- Left and up-do,m
and that will take out part of the remaLnder of the
forward velocity.
If it hasn ' t taken it all out ,
then bleep out the rest of the f orward .
I think
that 1s the only way you can do it if you want to
burn them al l t o zeros.
I don' t believe you can t r ack
any more precisely if you keep all your IVI ' s zeroed
right down the money.
If you burn it off and stop
just at the right time so that everything should turn
