4-26.
SITING OF TARGET SIMULATORS. (CONT)
5.
Rotate theodolite 90 degrees in azimuth toward radar set group (3) and lock in azimuth. Check that vertical
crosshair of theodolite is lined up with vertical center of radar set group.
NOTE
If crosshair is lined up with vertical center of receiver-transmitter, proceed to step 6; if not, move
theodolite in appropriate direction along clr and repeat procedure, beginning with step 4.
6.
Mark point (6) on clr where theodolite is located. Measure distance from mark to center of radar set group
(distance A).
7.
Set up theodolite at td point on clr. Direct second person to hold stadia rod on point marked in step 6.
8.
Sight vertical crosshair of theodolite on stadia rod. Record azimuth degree indication at theodolite reference
mark.
9.
Rotate theodolite 90 degrees in azimuth toward side of runway opposite radar set group (3) and lock in azimuth.
Record azimuth degree indication at theodolite reference mark.
NOTE
Theodolite is pointing along a line perpendicular to clr passing through td point.
10.
Direct second person to move stadia rod along this perpendicular line until it is a minimum of 75 feet (22.9 m)
from clr and lined up with vertical crosshair of theodolite. Mark this point (7) and measure its distance from clr.
