Requests for Navigational Aid Information 

TDp /P FROMpaOD DATE 18 May 1953 COMMENT NO. 1 

l. PROD bas recently been requested to provide information on Chinese radio 

transmissions for use in the navigation of aircraft over-flying China. As time did 

not permit the reference of this problem to higher authority for decision, the PROD 

reply was tbat no information was available of a classification which could be used 

for the stated purpose. In order that policy guidance may be available to guide 

PROD responses to any future requests of this type, it is recommended that the problem be referred to the NSA Classification Advisory Committee in order to obtain 

answers to the questions set forth below. (The answers considered valid by PROD on 

the basis of' a~ilable information are set forth in parenthes;s after each question.) 

2. Is the utilization of press and propaganda transmissions as navigational 

aids in over-flights of' this type governed by CQMINT security regulations and therefore a matter o~ concern to NSA? (No; these transmissions are outside the scope of 

CGMINT. Information of this type may be requested from CIA (FBIS) by the organizations concerned.) 

3. Is the use of navigational a.id transmissions, radio beacons, and other 

similar transmissions f'or these purposes governed by CGMINT security regulations 

and therefore a matter of' concern to NSA? (No; if such information is made available to the requesting agency by organizations other than NSA this if of no concern 

to NSA since such transmissions are outside the scope of CCNINT.) 

4. May NSA make available for navigational purposes information on radio 

beacon or navigational aid transmissions which is available only from CGMINT sources. 

(No; this information must be given the classification and codeword designation of' 

the CCMLNT source f'rom which it is available and the codeword designation prohibits 

use of the information f'or the indicated purpose.) 

5. May information (callsigns, frequencies, locations, types of' emission and 

services performed) published in "Berne Books" (publications of the International 

Telecommunications Union) be used for navigational purposes in over-flights of' 

hostile territory? (Yes; this information, although directly related to information 

of' a "TEX.TA" nature which is classified as SECRET CHUTE if derived from CCMI:NT 

processes, is unclassified as published in "Berne Books".) 

6. May NSA, on the basis of CCMINT information, select from unclassified 

"Berne Books" information known to be current and accurate f'or use in over-flight 

navigation? (No; the compilation, even though made up from an unclassified source, 

must be given the security protection of the information used as a criterion f'or 

selection.) '~'•';.;; ·~· ...... fH

7. Is TEXTA. information which is available to NSA. solely as the resul.t of 

intercept of foreign communications automatically classified SECRET CHUTE or 

higher, even though the transmissions in question are at fixed locations performing fixed services and empJ.oying fixed schedules and callsigns'l (Yes; this information normally can be compiled only after a COMINT effort has been appl.ied to 

raw material and it therefore must have a CCMINT classification.) I
