In addition to the stations listed above, a remote control station was
maintained aboard the USS Curtiss.
Preliminary dry runs in the’ Eniwetok area commenced on April 19,
1956, Preliminary dry runs started in the Bikini area o1 May 2. Drv runs
and tests were continved in both the Eniwetok and Bikini areas throuzhout
the test series.
.
A World Time rack identical to that used on Operations ‘Castle and
Teapot was iacluded in the design of the tiining system to record actual
zero time with respect to WWVH.
This measurement was obtained through
use of a 1000-cycle oscillator driving the World Time clock synchron'zed
to WWVH and located in the control room. The initial Sash of the detonation triggered a Fiducial Marker on the roof of the CP. This, in iurn,
tricvered a flash tube which produced a photographie record of the clock
face at zero time, and was accomplished by checking the clock reading with
the precise signals received from -WWVH,>
In addition to engineering assistants, a full-time technician wan assigned in each atoll to TU-6, the Firing Party.
Telemetering cquipment was installed as a part of the timing system.
Its purpese was to monitor vital information from the zevo site in addition
to various operations of the timing system.
Magnetie tape recording and playback equipment provided prerecorded
audio voice-time announcements synchronized to the timing system. The
- recorder was automatically started with the —15 min signal, and continued
to sive time hacks down through zero time. The voice count-down was
originated at the contro! station and further distributed to various ships and
stations about the atoll through the use of radio links.
A radio link was used to trensmit tone signals from the USS Curtiss
Abe

to the master control station, Fnyu.
Yhese signals were used in remotely
controlling the master timing station,
In order to provide timing signals to users at locations which were
inaccessible to the hard-wire timing system, a radio timing signal system
was provided, This system was synchronized to the master timing system
and transmitted various tone frequencies to radio receivers, which in turn
activated equipment at the uscr’s station.
