Report on Recent Collection Efforts
25X1
2. I lof AMS presented a briefing which showed that
1027, a search-survei ance mission, was operational for only one day, but
provided a total of approximately 24:9, 000 square miles of KH-4 cover
outside the Sino-Soviet area. 1028, a search surveillance mission, operated
for approximately 10 days, but the second half of the mission was only partially
successful, since the stellar index camera was not operating. However, the
mission did yield approximately 516,, 000 square miles of stereo panoramic
KH-4 coverage outside the Sino-Soviet area. Coverage obtained in this 25X1A
mission brought the total acceptable KH-4 coverage now on hand outside
the Sino-Soviet areas to a total of over 9, 000, 000 square miles.
demonstrated that the recoverage requirements approved last fall for approxi-
mately 400, 000 square miles inside the Sino-Soviet area were approximately
50"per cent fulfilled as of this time. These recoverage requirements were
related to obtaining improved coverage for purposes of both accuracy and
economy in those areas where both Army and Air Force production units
were presently preparing compilation bases. After discussion, it was con-
cluded that Army Map Service representatives should contact Air Force and
Navy production units, as well as the production activities within Army, to
update these recoverage requirements in keeping with planned production
within the next six months.
Research and Development Requirements for MC&G Acquisition Systems
3. I lasked for comments in behalf of the 25X1A
DoD with re and to the brief generalized paper on this subject as prepared by
I land circulated to members of the Working Group as MCGWG-D-
7 1, dated 25 January 1966. expressed that the paper prepared
by I did, in fact, represen a good start on a brief generalized
expression of MC&G requirements in language considered appropriate for
subsequent action by COMOR and USIB. He further indicated that while there
were significant modifications and changes in emphasis that DoD re resen- .
tatives felt were needed, such changes could be made in paper 25X1A
while retaining the basic approach used by Examples cited 25X1A
included the need to include accuracy requirements related to present weapons
systems, as well as future systems requirements, and the fact that present
satellite acquisition systems are not meeting all mapping and charting require-
ments particularly as applies to large scale maps. Further, the fulfillment of

positioning and elevation requirements, world-wide, needs to reflect the
input of overt acquisition systems, The Group discussed a number of
other considerations, and agreed on other minor modifications that would
improve the paper and retain the basic approach initiated by
stated that he would arrange for appropriate revisions as
discussed at the meeting to be made in the paper prepared byl
and that a second draft would be circulated for the review of committee
members prior to the next meeting.
Additions and Modifications to R&D Requirements
4. DIA had forwarded to the Chairman of the Working Group a
paper on the above subject based on the conclusions of the previous Working
Group meeting. This DIA paper set forth the basis for the accuracy require-
ments and expressed minor substantive modifications to the requirements
paper based on recent DoD experiences. In response to the Chairman's
request, briefly described the material covered.. Minor
modifications included increased detail requirements in all-weather sensing,
limitations of high altitude KH-4 for medium scale map production, and the
matter of expressing focal length for the index camera to improve geometry.
indicated that the DIA paper would be forwarded to members for
review, such that any comments on the substantive material presented could
be brought out at the next meeting,

capabilities and systems under fabrication. Accordingly, discussions involving
whether certain requirements could be accomplished by reconnaissance systems
or other systems in development were hampered by this lack of knowledge.
In some cases it may be possible to better meet MC&G needs with a modification
that could easily be made early in the development period. Further, this lack
of understanding necessarily leads to inappropriate substantive statements in
the R&D requirements paper prepared by DOD. While it was recognized in the
discussion that there should be a "need-to-know" aspect to acquisition systems
design and capabilities, the effectiveness of the MC&G Working Group was
clearly impaired by the lack of understanding of acquisition state-of-the-art
for satellite systems in general. It was recommended that the Chairman of
the MC&G Working Group arrange, either through briefings within the scope
of presently held operational tickets, or the granting of additional operational

 Scheduling of the Next Special MC&G KH-4
6. As agreed in the 17 January 1966 meeting,
reported that this subject had been considered within DoD, and it was
concluded that the first pan geometry KH-4 camera system that is now
25X1
25X1A
being readied for operational flight on the West Coast should be used for
the next special MC&G mission. It was held to be important that advantage
be taken of the pan geometry characteristics in obtaining MC&G coverage.
However, since the next pan geometry camera system would not be
available until July at the earliest, it would be best to make use of the
first pan geometry camera system in April, even though, originally, it
had been planned as a search-surveillance mission which would otherwise
have obtained pan geometry coverage only for test areas and other limited
coverage outside the Sino-Soviet area. In further support of this conclusion,
it was reasoned that if the pan geometry aspect was not completely satisfactory
on the first mission, we would still have KH-4 coverage consistent with what
we had obtained previously. It was brought out that it was already too late to
consider turning the camera system around, should that be desirable from the
standpoint of MC&G coverage requirements. However, it was determined more
important to obtain extensive coverage with the first pan geometry system,
even though the direction of the sun might permit some flare in the stellar photos.
indicated that he did not think there was any major reason why
the April pan geometry mission could not be used as a special MC&G from the 25X1A
standpoint of other collection requirements. of NRO, comrrac1
that he thought this could be arranged, but would need to make several inquiries,
and would have a reply in two or three days, at which time he would notify the
DIA member.
Pan Geometry KH-4 Coverage Requirements for Test Purposes
7. indicated that the MC&G utilization community
was anxious to obtain pan geometry coverage over ranges and other suitable
test areas for purposes of determining how well the pan geometry system was
performing in providing increased accuracy in compilation. Further, DIA
wanted to use pan geometry KH-4 photography for use in a comparative
production test for automatic plotting equipments now in use in the DoD, such
as the On this basis, recommendations were
received from Army, Navy, and Air Force as to appropriate areas, giving
consideration to weather and a cursory review of control accuracy and feature
identification factors. A preliminary indication of area requirements was given,

KH-4 Coverage for Control Point Identification

8. In accordance with paragraph 5 of the minutes of the
17 January 1966 meeting of the Working Group, I and
explained that the reason for requiring.KH-4 coverage for approximately thirty
spot locations, generally in the Southern Hemisphere, is for control identifi,-~
cation purposes. Army Map Service is working on a multiple orbit production
of the 0 photography for completion in July 1966. As input data, all of
the ground control that can be used in the orbit determination work should be
included by April 1966. A number of control points or control areas in the
Southern Hemisphere could be used with greater accuracy if intermediate scale
photography such as 1:300, 000 to 1:400, 000 were available for an intermediate
transfer ste between the large scale photo coverage of control points and the
small scale photography. DIA arranged for AMS to show the spot areas
on the KH-4 indexes as first priority areas until April 1966, The Working
Group agreed that NRO should treat these as first priorityKH-4 collection
requirements until April 1966, at which time DIA would recommend lower
priorities, as appropriate.
