Germany. The present system was designed approximztely 30 years 
ago for prime use in bomb drop trajectory studies and similar 
operations. The pulse type camera uses 35mm film stored in- 
ternally in the instrument on 100 ft. spools. Like any optical 
theodolite, the instrument is used to measure horizontal and 
vertical angles (azimuth and elevation) of a iine of sight. Two 
operators track an object along tbe path of a flight trajectory 
using exterior sighting telescopes. The primary telescopic ob- 
jective acquires the recorded data. The camera photographically 
records the object in flight, together with the azimuth and ele- 1 
vation dials, at specific time intervals. With the measurements 
obtained from two or more instruments at different ground po- 
sitions, 1t is possible to determine the spatial position of the 
Object being tracked. The AFMTC Cine-theodolites operate at a 
rate of 4 frames per second. The film format size is 56 x 35mm. 
The dial readings are projected to the upper left and right 
corners, and daytime filduclals appear at the center sides and 
center top of the frame. Night time fiducials appear in the 
dial reading blocks. A 24 inch focal length lens is normally 
used with the instrument. Timing marks snd frame number appear 
on each frame. 
Triangulation with the Cine-theodolite system does not 
explicitly utilize the orientation of the instrument, but 
rather uses the direction of the ray in space to the object 
being tracked. This direction is determined by applying a
