165 POSITION
a. LATITUDE AND LONGITUDE. Position in latitude and longitude will be signaled by two four/numeral groups, each group preceded by the letter P. The first group will denote degrees and minutes of the latitude, the second group will denote degrees and minutes of the longitude.
(1) ADDITION OF LETTERS. When confusion may arise, the letters N, S, E, or W may be added to denote North, South, East, or West.
(2) ADDITIONAL NUMERALS. When signaling longitudes over 100, five numerals may be used if necessary to avoid ambiguity.
b. OMISSION OF FLAG P. When position is referred to in the meaning of a signal group, the position indicator P may be omitted if the omission cannot cause ambiguity. Examples: NA22 Myposition (or ____ ) is as indicated by accompanying position signal. Time may be indicated by time signal. NA22—3215—7023—T16 Myposition is latitude 32°15’ longitude 70°23’ at 1600.

(2) TT — Originator’s present position.
(3) XX — The standard position established by the OTC on which a search, enemy reporting, andso forth, is to be based.
(4) YY — Addressee’s present position.
