1. Reference a. stated the DoD worldwide positioning requirements of
0
Geodetic System in support of long-range missiles.
2. Further reviews in January - March 1969 with regard to the urgency of
the requirement, and NRO problems of initiating the Doppler Beacon collection
in Summer of 1969, resulted in scheduling 4 Doppler Beacon KH-4B missions
beginning in March 1970 instead of 5 missions beginning in Summer 1969.

Doppler Beacons and antennae, all 6 remaining KH-4B DISIC (3" Frame Camera)
missions could be operated with the Doppler Beacon instead of the 4 presently
established. An increase of 2 KH-4B Doppler missions would have the

advantage to DoD of positioning a significant number of additional Priority I
targets in line with
increasing the positioning accuracy of other targets and provi

geodetic control for stereophotogrammetric mapping operations being conducted
Even though
25X1A
25X1A
25X1A
DISIC photography with Doppler Beacon might be partially cloud covered,
photogrammetric control can be established through use of the more precise
orbit. This permits control to be transferred to other cloud free
photography. The advantages to DoD far outweigh the
cost involved.
3. Requirements for target positioning and geodetic control for mapping
and charting include Northern latitude areas having limited light in winter
months. This will necessitate that some of the KH-4B DISIC missions with
Doppler Beacon be operated during summer months.
4. The Department of Defense had indicated a tightening of the worldwide
positioning requirement for long range missiles. Extensive research and
development has been performed on a continuous basis to advance the capability
of weapons systems. Major attention has been given to long-range missiles
and supporting activities including those contributing to reducing the
geodetic and geophysical error of missile operations. Factors of long lead
time for acquisition and data reduction and potential benefit in missile
effectiveness in view of the cost involved are the basis for the DoD
establishing a technical objective of reducing the positioning portions
of the geodetic and geophysical components of missile operations from
horizontal and feet vertical to
25X1
25X1A
25X1A
feet horizontal and =feet vertical 25X1A
by 1974. (All values 90% assurance relative the World Geodetic System).
5. The KH-4B DISIC with Doppler Beacon will meet the
El
(feet horizontal
feet vertical positioning requirement but will not meet the tighter
positioning requirement of

6. According to the NRO, the Doppler Beacon can be added to the KH-4B,
a. That USIB recognize the updated DoD worldwide positioning requirement

25X1 D
25X1A
in support of long range missiles as F-Ifeet horizontal and feet vertical 25X1A
25X1A beginning in June 1970 and a "feet horizontal and feet vertical 25X1A
requirement by 1974, all values 90% assurance relative the World Geodetic
System.
b. In view of the benefits to be gained and the relatively low cost
involved, it is recommended that the USIB agree that the NRO:
(1) Add the Doppler Beacon to 6 KH-4B DISIC (3"frame camera)
systems beginning in March 1970. (Instead of the 4 systems approved in ref b.)2 5X1 D
