Esuipoest and personnel were transferred ta the prowing ground in tine
to begin assembly and check-wut about 55 days before the Teak event.
Four
MIDOT statious (two on each island) were established for the Teak and Orange
events on Jotmston and Sand Islacts (Figs. 9.5 ami 9.6).
Electronic ecuip~
ment at each station was contained in a 9 foot instrumentation trailer.
Each
antenna was mounted on a pedestal, erected, and positioned by the field contractor according to specifications.
At the requesc of the Arsy Ballistic Missile agency (ABMA), equipment
was cbtained to enable the MIDOT system to track MRL pods used on Orange shot;
however, the equipment was not used because of changed plans in the field.

Data
Position data from MIDOT aeasurements are estimated to be better than
design limits by approxinately a factor of 2, giving su accuracy of > iGGO feet
in any dimension.
A comparison of the Orange burst pusition given by MIDOT
to the AKMA location determination, as specified in wr-1657," agrees within
1000 feet.
It is therefore believed that instrimenration locations quoted are
within a 2000-foot-diameter sphere.
Figures 9.7a through 9.7b are plots of
tange, altitude, and lateral displacement in feet versus time?
Ordinates are
referenced to Redstone launch coordinates and abscissas are referenced to
Redstone lift-off.
The Teak and Orange bursts were 170.6 and 154.1 seconds
after lift-off, respectively.
Table 5.1 is a tabulation of burst time co-
ordinates and slant range to the bursts.
Burst positions are taken froa
wr-1657," other locations frow Sandia MIDOT data.

Summary of System Perfor=ance
Teak.
Nine missiles were tracked during the Teak sbot, and satisfactory
Tecords were obtained on seven.
The two records not reducible are those from
the 80, 000- foot instrmentation rocket and one of the RF attenuation Viper-
Arrow II rocsets (see Chapter 7).
