(c) Memorandum of Understanding Concerning
Proposed Plain for Procuring Calibration
Information, dated 1~+ January 1g59
1. After consultation between representatives of the Aeronautical
Chart and Information Center and PIC it is possible to answer your
questions in reference (a).
2. In arriving at these answers, the a .-~~,~.e.~. memorandum of
understanding (reference tct) between CIA~pIC and ACIC concerning a
proposed plan for Processing Calibration Information was drawn up,
A few pertinent PIC observations on the memorandum are as follows:
a. ACIC agrees to supply calibration information
determined through this program to those users who require
it. A continued lack of rapport between ACIC (or the AF)
with the other services appearti~ to still exist. For
example, when it was pointed out to ACIC representatives
that Army Map Service and Navy Hydrographic office person-
nel are presently working at PI:G on other aspects of the
use of CIi~LICE materials for geodetic purposes, the ACIC
people declined the opportunity to talk with them, even
though it means that the work so accomplished would possi-
bly have to be done twice.
b. PIC will, still, even under the agreement, have to
train some ACIC people and provide the use of PIC measuring
equipment-and working space for three ACIC people. It was
explained that similar equipment is in use at SAC, but
ACIC still prefers to work here:.
c. PIC can furnish the information and material listed
in the agreement without undue strain on the facilities.

d. Paragraph ~+ of the agreement was written with the idea
that ACIC has some money available to spend on this program,
and by judicious application of this money through the proper
Operations people might accelerate the reconstruction of dis-
mantled cameras and the exposure of stellar negatives by Hycon
personnel. This is an operation currently being pursued by
Hycon, but only on a time-available basis. PIC has not
attempted to have this accelerated a~ we are unable at present
to reduce the data from negativE~s on hand, because of our
current work load.
3. specific answers to your que.stions-
a. The cost of the operation is small, and apparently
the Air Force is willing to underwrite it.
b. For camera focal length calibration, stellar exposures
must be made with each camera. This data must be reduced
mathematically. This will be done at PIC on the electronic
computer. Distortion and interlock angle calibration has yet
to be investigated, but the material f~.a.rnished to ACIC by PIC
will enable ACIC to perform this investigation. Once the
feasibility has been proven, this matter will, be approached
as an entirely separate problem, as there are other pertinent
considerations.

c. At the present, or until the feasibility of performing
distortion and interlock calibration is proven, it is antici-
pated that there will be no impact on operations at -
d. No additional CHALICE clearances are required for the
portion of the program planned to be undertaken, the focal
length calibration and investigation of other calibration
possibilities. Three ACIC people presently hold CHALICE
clearances. They will do the planned work.
e. No additional requests j'or TALENT clearances are
expected from ACIC beyond those currently planned, should the
calibration program prove the possibility of geodetic exploi-
tation of TALENT materials. Undoubtedly other military
mapping and charting agencies, A~~ and Navy HO particularly
would request additional clearances once the program was a

proven success. At that time, there would probably be requests
also for additional cleared working areas. No estimate of
these factors is being r~a.de at this time.
~-. It is PIC~s desire to physCeally relocate the pursuit of this
problem at the earliest convenient date. After training of ACIC people
is accomplished at PIC, estimated to take about 2 weeks, the only
operation which will remain at PIC gill be the measurement of stellar
images and the computation. A continued attempt to move the measure-
ment operation to SAC will be made, However, the computation will
probably continue to be done at PIC.. This is a small problem, since
the necessary computer program for reduction of the data has been
accomplished.
5. By way of summary then, it is estimated that we can provide
some of the geodetic help so desperately needed by ACIC for a reasonable
amount of continued support from PIC~s Technical Intelligence Services
25X1A Division. No additional CHALICE clearances would be initially required
and there would be no impact on operations at ending ACICts
investigation of distortion and interlock ang e tali ration data. If
this investigation proves the value of this data, some future request
from ACIC would probably involve more CHALICE clearances. ACIC does
have some funds for dismantled camera reconstruction and the stellar
exposure programs at HY'CQN if Ctperations had no objection and a posi-
tive interest in these results. Despite Air Forces continued
apparent intention of -going after the calibration-control extension
problem unilaterally, it would be willing to share the calibration
results with those users who require them. We would continue to try
to convince ACIC that the measurement operation should be moved to SAC
and out of our crowded. working areas. We are .able to handle their
machine computations for data reduction without too much strain.
6. Before confirming any of these arrangements with ACIC we
would have to have your endorsement or the opportunity to meet with
your people and offer such additional details or clarifications as
you might require.
