to reconcile conflicting trajectories by "hanging" them upon a
ballistic camera trajectory which, in turn, is "hung" upon the
stars.
CONCLUSIONS
A major disadvantage of optical data is the extended time
cycle between the missile test operation and the publication of
the final reduced data. Under present operating conditions the
time cycle for optical data reduction is in excess of 7 to 10
days. For the future, consideration is being given to a 6 hour
ballistic camera reduction; to be accomplished by plate processing
and reading in the field, and the data transmitted to the com-
puter center for reduction. Also being considered for the near
future is a 72 hour CZR Fixed Camera reduction, which together
With the 72 hour Azusa reduction will present an entire missile
trajectory. The shortened Fixed Camera reduction will necessi-
tate only a revision of current operating procedures such as
ready availability of overtime man hours, immediate-upon-call
computer utilization, and release of data in tabular and/or tape
computer output form rather than in a finished report.
The problem of increasing the accuracy of the Fixed Camera
and Cine-theodolite systems is within the capabllity of the
