We knew we were right on in yaw al l the wey down the
line, and we could just name the stars and knew that
t hey were just going to come right down the middle
of the pipe, and watch them go. It worked real well .
How long did you aline the platform for retrofire?
Well, we really alined it about 1½ orbits.

We powered up for~ and we actually were alining
for an orbit and a half before retrofire .
All the
alinement and everything was done on the RCS system.
Let me sey this on this alining.
We found that we
couldn

after an orbit and a half.
We were doing it in
horizon scan, BEF, and then using the pulse mode in
the horizon scan to give you the fine control within
the horizon scan to really keep the needles closely
centered.
Now you can do the same thing just in pulse,
but if you neglect it for just a minute, the horizon
scan would hold it in there real close .
