MEMORANDUM FOR THE UNITED STATES INTELLIGENCE BOARD
SUBJECT World-Wide Positioning Requirements
REFERENCE USIB-D-41. 14/295 (COMDR-D-13/65), 1 1 July 1966
1. T:he attached memorandum from the Chairman, Committee on
Imagery Requirements and Exploitation (COMIREX) submits for USIB consider-
ation recorrtmendations on the subject designed to meet these requirements as
defined by the Mapping, Charting and Geodesy (MC&G) community based upon
proposals furnished by the National Reconnaissance Office (NRO).
2. A s background the attached memorandum gives the COMIREX
evaluation of NRO proposals designed to meet the DoD world-wide positioning
requirements as stated in the reference of 450 feet horizontal and 300 feet vertical
90 percent ~~.ssurance relative tr~the World Geodetic System in support of 1
range missiles, with particular reference to accuracy in the Sino- Q1 D .
Soviet area. The NRO proposals involve adding a Doppler beacon to the
T'T~ A"
system beginning in the summer of 1969,
USIB ACTION. REQUESTED
3. Board Members are requested to advise the Secretariat not later
than close of business 4 November of their concurrence or other views on the
COMIREX recommendations in paragraph 6 of the attachment.

MEMORANDUM FOR: The United States Intelligence Board
SUBJECT: World-wide Positioning Requirements
REFERENCE: USIB-D-41. 14/295 (COMDR-D-13/65), 11 July 1966
Background
1. Referenced USIB document stated the DoD world-wide
positioning requirements as 450 feet horizontal and 300 feet vertical
90 percent assurance relative to the World Geodetic System in support of
long range missiles, but indicated that this requirement would probably
be met by existing overt and covert systems and data. The MC&G community
later stated in July 1967 that the requirement could not be met because
existing systems could provide only a 750 feet horizontal accuracy in the
Sino-Soviet area. Accordingly, the COMIREX asked the :tVRO for proposals
to meet the requirement as defined by the MC&G community. NRO proposals
furnished. in August 1968 have now been evaluated.

3. Long range missiles requiring the positiariing accuracy
stated an paragraph 1 above to be compatible with other characteristics
will be operational in June 1970, but data on which to base the geodetic
calculations should be available 6 to 12 months in advance. At the pre sent
time about oxie third of the DaD's Priority One missile targets meet this
po-sitioning requirement, but over 800 have a horizontal accuracy averaging
750 feet and ranging from 450-1000 feet 90 percent assurance. About 85
pex?cent of these targets are missile silos. We axe informed that efficiency
and flexibility in planning the use of our special weapon strike force cannot
be achieved unless immediate steps are taken to bring target positioning in
line with the. improved Minuteman capability.
4. Immediate action to place the Doppler on the KH-4B will
provide for meeting the current requirement of the missile force for the
more important targets in June 1970, which would be abort tvvn trPar~ o~ri;,,~.
Impact on Intelligence
5. According to the NRO, placing the Doppler beacon on the
KH-4B will not materially change the mission parameters optimized for

intelligence requirements, but increased power and weight requirements
ma;y cause a slight reduction of time on orbit for ona mission. After the
solar panels are available for power supply in March 1870, there will
be no reduction in time on orbit. On balance it is expected that increased
accuracy can be realized from geodetic positioning by the KH~4B system
without signi:#icant impact on meeting intelligence requirements.
Recommendation
6. In view of the benefits to be gained and the relatively low
cost involved, it is recommended that:
a. The NRO take immediate action to
add tY~e Doppler beacon to five KH-4B systems
beginning in the summer of 196 q.
