MEMORANDUM FOR THE RECORD
SUBJECT: High Precision Stereo Comparator, NPIC Project 11038
1. 1 P__ e nical Director,
visited NPIC on 24 and 25 September 1968 anProject
Manager for the Comparator, visited NPIC on 25 and 2 September 1968.
2. In the AM of 24 September,II and the technical monitor
attended a meeting in TSSG/TSD at which math models for strip photography
were discussed? I :J and three members of his branch along with
of IEG/PHD were able to provide with a great deal of
valuable information for use in his computer programmin of correlation
and stage tracking functions of the comparator system. also
arranged for to get a briefing and further information on the math
model work t Ln lace in the Center. This took place in the PM of 25
September andreports that it was most helpful.
3. In the PM of 24 September, met with
of TSSG/TPD. The electrical interfacing of the Model 35 teletype with the
On-Line Central Computer was examined and information exchanged. This pro-
blem seems to be pretty well resolved.
4. During the last two hours of 24 September,
of IEG/PHD provided Skiff with additional information on pan photography.
5. On 25 September, gave I Ia our of
the TSSG/TSD clean room. The laminar I ow and tile Kozitron Filter units.
were inspected. This is somewhat like the system that will house the
Comparator. A short tour was also made of the proposed site for the com-
parator on the first floor. Problems of bringing in the granite slabs
were discussed. and they do not seem to be too serious.
6, and e technical monitor also had a meeting with
I Io ID. I Istated that their Model 35 teletype was
wired for an level code an as ed if tlis was acceptable to the central
computer. I I stated that they used a 7 level code but this was no
serious problem since the 8th level is only a parity bit. inquired
about the stereo program for the central computer and stated
that it is still not on-line. II stated that part o e program-
mi.ngwas completed an that the on- ine o eration will be ready when the
comparator is delivered next year. II stated that the answers or
distances computed for the stereo program will not be instantaneous as they
are on the mono program. The stereo program will store some of the items
in memory and later send back the answer to the computation.

Some time was spent discussing how the Central Computer and the small

he would have to queryl _j Chief of Photogrammetry Division, to see
if IEG/PHD, TSSG/TSD, or PSG/AID will do the DDP-516 programming for any
future acquisition systems.
7. In the PM of 25 September, 0 and the technical monitor met
with to discuss the conceptual design for the site pre-
paration and the clean room for the comparator. Copies of drawings on the
site re aration, air conditioning, and power requirements had been submitted
to e
for review prior to this meeting. The plans and performance for
the "black box" were studied and= promised to supply copies of the two
bids that are due 27 September 1968. Plans call for the black box to be
completed within 120 days of contract date. The possibility of sending the
"black box" to for checkout with the optical system was discussed.
Several modifications were made to the power requirements to insure
that overloads would not occur during certain critical operations. Several
changes were also made to the air flow around the operator to insure that a
dead space did not occur that would allow dirt to build up. The rate of
flow of air from certain lines was modified to insure adequate cooling of
critical items.
The machine room was thoroughly reviewed and plans made to allow room
for the vacuum pumps and other ancillary equipment. Ore sted that
the height of the room be increased from 8 ft. to 9 or 10 ft. said
this would greatly increase the cost of operating the room an d ue sal he
would attempt to increase the height to a minimum of 8 ft. 6 inches. To
provide overhead room for removing the covers of the optical bridge for
maintenance on the optics, provisions will be made for an eight foot section
of the ceiling to fold back on hinged panels over the bridge of the compara-
tor. 0 stated that he was concerned about getting the 85 inch high
electronic cabinets through the security vault doors used in
stated that 96" high vault doors would be installe e weep
hat would allow free movement of the cabinets into the site.
Indications are that the close coordination with Logistics and r
have paid of. It looks as though the site and clean room will provide zoi
all the requirements of the Comparator. 0 asked when actual construc-
tion would begin on the site. stated that Logistics was still
awaiting NPIC authorization to usel on an Architectural and
Engineering Contract to design the site and clean room.

I Ishowed him how some of the mensuration instruments were
operated an allowed him to work on some of the instruments that were not
busy with production items. 0 also spent time observing operators
performing mensuration operations on actual production jobs on several
different instruments.
Some time was spent discussing just how and why operators perform
certain functions in specific orders. The concensus of opinion, with which
the technical monitor agrees, is that it might be a good idea forlI to
spend some time in November working in IEG/PHD. Teach him the usual measur-
ing procedures and allow him to perform measuring tasks on actual jobs that
have been run by IEG/PHD. While he is quite com etent to check the quality
of the optical system being fabricated b e should have a working
knowledge of its intended use so as to determine if it is operatin ro erl .
Since he will be checking out these operations as a sole judge at
he shou e t.raine to.-opera e stereo-instruments-so that he can evaluate
from an operational standpoint. If approval is granted by both and NPIC
management, t_he week of 18 November 1968 might be a good time or to
work in IEG/PHG.
9. Arrangements have been madn for to visit
on 9 October 1968 and for and the
technical monitor to visit on 9 and October 1966.
