SUBJECT: Staff Study Concerning Reduction of to from
STAB OF THE PROBID4
equested that WPIC obtain a contract from
for attitude determination frow stellar e poeures taken
I
r~ vas~f,, at~3n
from the next and subsequent CAA missis.
1. On the next and subsequent COEC A missions re viii be a
camera linked together with the terrestrial framing ra, that Vill
photograph the stars. The purpose of photographing stars is to
enable the accurate orientation Of the vehicle and terrestrial camera.
THE FACTS
2. NPMC does not have the production capabili to reduce data
from the stellar exposures even though it has the requirement.
3. because of their participation in the "A" program,
has established efficient production procedures and instrumentation for
the reduction of attitude from stellar exposures.
DISCUSSION QF THE FACTS
and y of the vehicle
and/or terrestrial exposures the foaring procedure
1. In order to determine the pitch,,
b. Boss catalog of stars must be entered I
NPIC does not have this capability at present.
c. The star images must be measured.
are necessary:
a a computer,
d. The measurements must be reduced in thh computer. NPIC
does not have the necessary program for this rec cti.on. Items
b and d above preclude any attempt that TID reduce the stellar data.

2. ' next CQRONA mission lawn probably within the next
two w*&s. It is the intent that 7" receive the stellar
exposures, reduce and forward the data to At some date in the
future, when TID h sufficient personnel and the pr jeer ccmputer
program for this type of problem, NPIC will phase out Autc uetrics
and assume the entire responsibl ty".
It is reac am wiled that MC obtain a contract f c to
reduce the required. attitude parameters from stellar jexposures until
such time that Tfl) is nth a position to do the job.
