.MEMO FOR RECORD (FILE: R&D
Subject: Customer Requirements for Annotated Data
1. On this date, we met with two men of the Customer's Office to
discuss the Code Matrix Block (CMB) of MIL-STD-782A, "Tactical
Reconnaissance Data Marking", as it applies to our system. The
meeting was quite fruitful and produced some information useful to us.
2. Although the visitors felt that the Standard data would be very
helpful, they had thoughts on those items of data which would be more
helpful to them. It is good that most of the items they feel to be
desirable are already available somewhere within the air vehicle or
the sensors, which means that we might be able to satisfy their
requirements with only.small additional effort.
3. As a result of specific questions posed -to the visitors; we
learned these facts:
a. Storage and retrieval: The Customer does not presently use
film chips for storage of intelligence film, nor is there expectation
that film chips will come into use within the next several years.
At present the storage of original negative (ON) material is in rolls
with average length of 250'and it is likely. that the ON's from our
vehicle will be stored similarly.

d. Present Data: The Customer fools that certain items of data
presently in the cameras and other sensors may be retained, and that
some may or should be removed. To be retained should be the frame
counters, sensor serial numbers, lens serial numbers, and CFI, numbers,
where they exist, while the clocks, the writo-in data cards, and other
items of data not mentioned should be removed.
e. Additional Data: The Customer fools, main as we do, that the
CMB should include some additional items for information not presently
readily available in the,air vehicle or the sensors: pointing angle
indication, frame count indication, V/H ratio-,, cage indication, and
operating mode.(these are covered in more detail below).
number forms part of the accession number, with the balance being the
sortie number and date, As noted above', the Customer suggests that the
analog presentation of frame count be retained where it already exists:
if this is done, then the binary frame count indication must be matched ?
to the analog presentation, to preclude confusion in reading. It
remains to be seen what the final disposition of the analog frame count,
mechanism will be; however, the requirement for binary presentation of---
frame count is firm.
6. The frame count appears to be an important item of information for
the Customer, especially since the ON is filed in complete rolls, for the

useful in cases where the vehicle maneuvers oauao the sensor to operate
against the stops. The presentation would be ono-digit indication of
the "go-no-go" type. The operating mode would be applicable to those
sensors in which more than one mode of operation was eeleotable, for
examples
a. TROCs 55% overlap or 10% overlap.
be OOC: No mode selection is available.
c. TEOCs Mode 1, Mode 2, or Mode 3.

The signal for this indication could be generated externally to the
sensor and inserted at the appropriate place in the CMB.
9. One final item of "new" data is that of the "Sensor Identity". There
has been some discussion of the-usefulness of this item of information and
the manner in which it should be pr,:,:;entpd. The Standard specifies three
characters for the presentation, which apparently presupposes a. universal
coding system. The Customer will look into the subject further, for he
has several other systems in which the CMB is used, and it appears that he
would be the most logical assignor of codes to be used.
.10. The Standard is quite specific on the matter of positioning of the
CIS relative to the frame of photography, the reason being to assure
compatibility with the automatic reading devices. If the needs of this
Customer are to be the criterion, then we can aszmne much greater flexibility
in the positioning of the CMB. recording head, for the Customer currently
has under development an automatic reader which is quite versatile. The
reading head can be positioned any where within an envelope with a 9 inch
travel across the film, and a 5 inch travel along the film, both of which
should-accommodate the positioning 1.rhich will probably dictated by existing
configurations of our sensors. A very important facet of the Customer's
operation is the manner in which the automatic reader is used; the Standard
presupposes that a reader is used for search or for some other purpose which
.requires the CMB to be at the leading edge of the frame of photography; - the _
Customer is unconcerned with the relative position of the CMB since the
proper sequential position is all that is required. The CMB is used
primarily to present information through the reader onto a magnetic tape
for ultimate computer use. All in all, then, it appears that we have had
a severe constraint removed from the installation requirements for the
recording head.

11. Speaking of tapes, the Customer made a point which is not germane
to the problem at hand, but it will require action at some time. The
Customer has use for the mission recording tapes (or extracted portions
of the tapes) for use in evaluation of the imagery. The evaluation is
made only when the imagery is less than specification quality, or when
serious degradation is present. In those instances when the imagery is
completely acceptable, the mission recorder tape is not used; the
decision lies with the Customer, though, so the tape must be supplied.
?12. In summary, we now have sufficient information on which to take a
stand for the format to be imprinted on the several sensor films. The
first attachment presents,. in tabular form, those items of information
which are suggested and desired by the Customer, with indications of which
are already available and those which must yet be made available. The
second attachment depicts a recomrrmr 'er1 arrangemen~ for the several items
which must appear within the CMB. ly _-,c noted that maximum usage
is made of. the spaces which alreti -L ,h are for optional
use. Only one item is recommends,. from the CMB, and
that is the "Detachment and Squad. for the joint opinion of
the Customer and of the SPO that tern is probably the least important
of all on the format.:
