CHARTER 

FOR . 

MOL IMAGE VELOCITY SENSOR (IVS) REVIEW GROUP 

OBJECTIVE: To conduct an independent and critical review and 

assessment of contractor work to date on the MOL IVS. 

BACKGROUND: The concept of an image velocity sensor in the 

MOL Program assumed critical importance at the time the 

decision was made to proceed with an unmanned version of 

the DORIAN payload. While this device is highly desirable 

in the manned configuration of MOL to reduce demands on the 

astronauts time, it is essential for system performance in 

the unmanned configuration. The purpose of the IVS is to 

passively sense errors in the ground tracking rate of the k4' 

tracking mirror and produce useable correcting signals of 

specified value to the tracking mirror drive to contribute 

to the reduction of the photographic image rate at the center, 

of the film format to within system specifications. In vie 

o: the criticality of the IVS to system performance and the 

difficulty of the technical task, three separate technical' 

approac.Ies were undertaken by three different subcontractors.. 

to General Electric who is the associate contractor responsible 

for this task. For the afore mentioned reasons of criticality

and complexity coupled with the obvious need for fixing on the 

most feasible and promising approach at an early date, an 

independent assessment of the current status of the IVS work 

• 

is deemed desirable. 

SUGGESTED APPROACH: Review and analyze MOL system design and 

performance requirements for the IVS. Examine the programs 

of each of the subcontractors analyzing the responsiveness of 

their approaches to system requirements; their design approaches; 

theories of operation; rationales for selecting their approaches; 

performance limitations; suitability of performance trade-offs;' 

test programs; major problem areas; and proposed fixes. 

Examine the General Electric test program for each of the 

vendors' items for adequacy, pertinence, and technical competence. 

Evaluate each of the vendors with respect to each other and the 

overall conduct of the work by General Electric. 

RESULTS DESIRED: A. written report summarizing the views of the 

Review Group which evaluates each of the vendors' programs; 

.• 

the General Electric program; and expresses a level of confidence 

for each of the vendors and the overall program. A. welcome 

addition to the Review Group's evaluation would be their 

recommendation for alternative technical approaches, modifications of the current approaches and the identification of 

additional desirable development activities.

Ad Hoc Review Group on the MOL Image Velocity 

Sensor (IVS) 

The purpose of this memorandum is to provide you a 

status report on preparations to date for the Ad Hoc Review 

Group on the hOL IVS. I met with Dr. Brian O'Brien at 

Andrews on August 19 and outlined our tentative plans to 

conduct the review at General Electric, Valley Forge on 

September 19 and 20. We briefly discussed the IVS problem 

and the composition of the Ad Hoc Group. He seemed quite 

enthusiastic about participating as Chairman of the group 

and concurred with my outlined plan. 

I have discussed the composition of the Ad Hoc Group 

with a number of individuals with the view of obtaining the 

right mixture of expertise and skills for the purpose of 

insuring an adequate technical balance with a small number 

of people. It appears that Dr. Cannon will not be able to 

participate due to other schedule commitments. At the moment 

the tentative organization of the group is as follows: 

Dr. B. O'Brien, Chairman 

Dr. Brockway McMillan (not confirmed as yet) 

Mr. Harry Davis 

Dr. M. Yarymovych 

Colonel L. Alien 

Mr. L. Crouch (UDC) 

Mr. J. McFadden (Dyametrics)

for the meetinz will consist 

ee eee Le d, • s--ond day for discuneLee 0,4 4 

preperation of the report. Cenerelly, the briefings will 

incluee a brief review of CLe ov:rall LOL Prozrem; a sumeary 

of General Electric IVS roeponsibilitics; a review of the 

IVS re:.Teiree.ents; presentneions by'the three vendors, following 

as ?reser:LI:oz.!. format in which the vendors discuss their understendin of the requiremenz:e, their design approaches, theories 

of operation, ratioaales for selecting their approaches, 

performance limitatioas, suizability of performance Lt ade-offs, 

test prograns, major problem areas, and proposed fixes. At 

the conclusion of the vendors' presentations, General Electric 

will then present the content of their test program of each 

of the vendors' items. This will be followed by the MOL 

Systems Office/Aerospace eveluation of the program to date 

and a brief discussion 3! t.he. operational concepts for 

em?loyment of the IVS. 

FollaAng the presentations, the group will go into 

executive session for the perpose of producing a written 

report which evaluates each of the vendors' programs, the 

General Electric prosrem and expresses their level of confidence for each of the vendors and for the overall program. 

Additionally, feey will be asked to express their views 

on alternative technical approaches, modifications to the 

current approcches, and the identification of additional 

desirable development activities. 

2rem a long range view, I an now planning, and I will 

consult with the group, to reconvene them in about six 

months for a follow-up aession., I will ask Dr. Cannon to 

participate at that time. 

As soon as the specifics are defined, I will provide for 

your c.oproval, a charter for the group, and a letter for your 

signeture to Dr. O'Brien formally requesting him to Chair the 

group.
