INTROCUCTION
Principal aims of the radio-frecucncy (RF) sessuresents prosraa were three
fold:
(1) ro prowe the feasibility of a aodificarion of the Sandia-developed,
SOW-ac high-resolution telemetering system to obtain diagnostic inforaation
ca tests at very high altitude; {2) to deteraine relative positions of the °
Redstone missile and the Sandia instrimentation rockets at burst tine; (3) to
transmit data gathered in the Redstone and in the instrusentation rockets to
ground recording stations; and (4) to record RF signal strength from the instrument carriers to supplement Project 32.3 RF attenuation data.
To accomplish these objectives the following three separate subprojects
were organized:
{1) high-resolution telepetry, (2) positioning systea, anJ
£2) FN-FM telemetry.
Equipment, operations, and results of the systems evolv ed
are discussed.

Design Criteria
In order to proof-test the 4000-mc system for rocket-borme nuclear shots
it was proposec to aake quantitative measurements of early alpha ‘nucber of
e-fold increases in fission reactions per unit tine in the prisoary of the warbead) and transit tine (time between fire signal and start of the chain reaction) of the warhead used in the Teak and Orange events.
Conditions affecting
choice and desjgn of equipment were deternined as follows:

station was expecred to be approxisotely 50 ailes.
