(4) Position accuracies of the Redstone delivery system were predicted
to be:
(a) Burst point range error = 2 1300 feec
{b)
Burst poice altitude error = + 1000 feet
(c) Burst point azimuth error = 7 350 feet
(d) Pitch and yaw error of Redstone = t 1 degree
(e) Roll error of Redstone = 7 5 degrees
(5) Peraissible size of the transmission equipment was liaited to a wolom
of about 8000 cubic inches in the Redstone.
(6) System weight should be less than 350 pounds.
(7) Time from initiation of design of transaission equipment to final use
was approximately one year.

aminimm.
Development costs had of course to be held to
To avcid loss of control of the development schedule, developaent
of any major portion of the equipment could not be contracted to a supplier.
The desire to use a minimm oumber of people in development and operations
tended to restrict development work to equipment with vhich available personnel
were familiar.

Description of Systea
In the following description a signal is traced from its origin in the
detector through the system to the transnitting antenna as outlined in the
block diagram of Fig. 9.1.
A complete technical description of the systen
has been given by Brimley and Schultheis.!
Gamma radiation generated by
the exploding bomb enters the detector case
causes fluorescence of
‘the plastic fluor inside.
This fluorescense is detected by two photocultipliers
and one photodiode oounted within the fluor.
The threshold levels of these
Cubes are so adjusted that the ratio of light inpuc necessary for initiation
of conduction of the successive stages is 1000 to 1.
The outputs of these
tubes are sent to the modulating circuitry where they are differentiated acd
sent to the minimazgnetcon.
