avoid confusion the five figures should be used. The letters ―E‖ (East) or ―W‖ (West) follow if they are needed, otherwise they may be omitted, as in the case of latitude. ? Example: ? ―G13925E‖ = ―Longitude 139176。2539。 E‖. 通信要素的表示方法 ? Distance ?Figures preceded by the letter ―R‖ indicate distance in nautical miles. ? Example: ? ―OV A080 R10‖ = ―Mine(s) is (are) believed to be bearing 080176。 from me, distance 10 miles‖. ?The letter ―R‖ may be omitted if there is no possibility of confusion. 通信要素的表示方法 ? Speed ? Speed is indicated by figures preceded by: ? (a) the letter ―S‖ to denote speed in knots, or ? (b) the letter ―V‖ to denote speed in kilometers per hour. ? Examples: ? ―BQ S300‖ = ―The speed of my aircraft in relation to the surface of the earth is 300 knots‖. 通信要素的表示方法 ? Time ? Times are to be expressed in four figures, of which the first two denote the hour, from 00 (midnight) up to 23 (11 .), and the last two denote the minutes (from 00 to 59). The figures are preceded by: ? (a) the letter ―T‖ indicating ―Local time‖, or ? (b) the letter ―Z‖ indicating ―Greenwich Mean Time‖. ? Example: ? ―RX Z0830‖ = ―You should proceed at GMT 0830‖. 通信要素的表示方法 ? Depth ?

OC 6M = My draft forward is 12 meters ? MU 18F = My draft is 18 feet. 通信要素的表示方法 ? Transmission Method of Communication Elements in Signal Code Message ? A+3 numerals — Azimuth or Bearing。 ?

CALL SIGN ? 船舶呼號(hào)( CALL SIGN),是國(guó)際海事組織 IMO指定給每條船舶唯一的識(shí)別信號(hào),屬于海上通信識(shí)別方式之一 【 Ship ’s name, Call sign, Identity code( Maritime Mobile Service Identities) 】 。 ? 主要作用:在船舶海上聯(lián)絡(luò)、碼頭靠泊、信息報(bào)告的時(shí)候使用。就好比船舶專(zhuān)用身份證一樣,因?yàn)槭褂脭?shù)字信號(hào)或者報(bào)告船名在識(shí)別上由于發(fā)音問(wèn)題可能導(dǎo)致誤解,所以采用了專(zhuān)用的呼號(hào),呼號(hào)的發(fā)音也是特殊專(zhuān)用的,很容易識(shí)別。 CALL SIGN ? 船舶呼號(hào)的組成 ? 船舶呼號(hào)是船舶所有國(guó)政府指定給該船的一組字母和數(shù)字,常有四個(gè)或四個(gè)以上的英文字母或字母與數(shù)字混合組成。起始的一個(gè)或兩個(gè)字母通常代表船舶所屬國(guó)。如: ? 中國(guó) ——BAA~BIZ, 3HA~3UZ; ? 英國(guó) ——GAA~GZZ, 2AA~2ZZ; ? 日本 ——JAA~JSZ, 8JA~8NZ。 CALL SIGN ? 呼號(hào)的用途 ?呼號(hào)是特指某船的一組符號(hào),代表船舶的名字,但比船名更可靠,并且方便簡(jiǎn)單,在通信中互相識(shí)別時(shí)經(jīng)常使用。 ?( 1)與某船臺(tái)通話或呼叫某船臺(tái); ?( 2)通信中講到或指到某船臺(tái)。 ?
