The early emphasis at SCI on air and underwater launched missiles 

 produced a need for facilities capable of supporting air and underwater 

 launch programs through the research, test, and initial evaluation phases. 

 Thus the numerous test facilities at the Ocean Engineering Range incor- 

 porate a wide variety of instrumentation to ensure full documentation for 

 any test series. This consists of electronic, photometric, communica- 

 tions, oceanographic , and weather instrumentation. 



The electronic instrumentation at the Island includes radar, teleme- 

 try, radio command control (destruct), correlation timing, closed- 

 circuit television, and meteorological units. All electronic facilities, 

 except the main telemetry station and the meteorological station, are 

 housed in vans or trailers. This feature enables range configurations to 

 be altered to suit any test requirement. 



Telemetry (TLM) capabilities consist of RF-link receiving- 

 demodulation-recording facilities compatible with standard Lnter-Range 

 Instrumentation Group (IRIG) carrier-subcarrier assignments. The main 

 TLM station is situated at an elevation of 600 ft and overlooks Area "A. " 

 Closed- Circuit Television (CCTV) is used to provide range-control per- 

 sonnel surveillance of several functions at one time or to enable observa- 

 tion of events in hazardous areas. In addition, many underwater televi- 

 sion systems (both shallow and deep submergence) have been developed 

 by NUC and are used by various projects. 



Photometric facilities at the Island are capable of recording external 

 data and documentary coverage of any test, either underwater or above. 

 More than 200 concrete camera pads have been constructed on the Island 

 to accommodate any of the wide variety of photometric instruments in use. 

 Photometric data provides a timed record of visible events, including 

 space position versus time, as well as attitude, velocity, and accelera- 

 tion of flight-test vehicles. The nucleus of the data package (space- 

 position) is supplied by askania cine theodolite instruments. These track- 

 ing cameras are fitted with relatively long-focal-length lens systems and 

 operate at low exposure rates up to five frames per second (fps). Bowen 

 cameras are preoriented to a specific point in the missile trajectory and 

 provide highly accurate acceleration velocity and attitude data because 

 of their greater exposure rate, 30-180 fps. Typical events covered by the 

 Bowen cameras would include launch sequence, stage separation, and im- 

 pact. Additional photometric coverage throughout a missile trajectory is 

 provided by several types of high-speed 16-, 35-, and 70-mm cameras. 

 The high-speed data cameras may be used as tripod-mounted, fixed instru- 

 ments or may be placed on M-45 tracking mounts coupled to a variety of 

 lenses (up to 200 in. ). Underwater photometric requirements are fulfilled
