CHAPTER 1

RADIO DIRECTION FINDER AND RADAR STATIONS

PART I RADIO DIRECTION FINDER STATIONS

100A. General

Radio bearings may be employed for fixing a ship’s

position in the same manner as other lines of position if

due regard is given to the facts that they, like other lines of

position, may not be absolutely accurate, and that the

bearings are portions of great circles, not rhumb lines.

Radio bearings are obtained using radio direction finder

sets installed on either shore stations or ships, and also by

certain special radiobeacons.

Radio direction finder (RDF)stations are equipped with

apparatus for determining the direction of radio signals

transmitted by ships and other stations.

SECTOR OF CALIBRATION: The sector of calibration

of a direction finder station is the sector around the

receiving coil in which the deviation of radio bearings is

known. In this book, the sectors are measured clockwise

from 000 ̊ (true north) to 359 ̊ and are given from the

station to seaward. Bearings which do not fall within the

sector of calibration of the station should be considered

unreliable.

100B. Accuracy of Bearings Furnished by

Direction Finding Stations

The bearings obtained by RDF stations and reported to

ships are corrected for all determinable errors except the

difference between a great circle and a rhumb line (See sec.

100F.) and are normally accurate within 2 ̊ for distances

under 150 miles. However, this error may be increased by

various circumstances, some of which are:

STRENGTH OF SIGNALS: The most accurate bearings

result from ships whose signals are steady, clear, and

strong. If the signals are too weak, accurate bearings

cannot be obtained.

TRANSMITTER ADJUSTMENT: The transmitter of

the ship requesting bearings should be tuned carefully to

the frequency of the station. If the tuning is off, it will be

difficult for the station to obtain bearings sufficiently

accurate for navigational purposes.

COASTAL REFRACTION (LAND EFFECT): Bearings

which cut an intervening coastline at an oblique angle, or

cross high intervening land, may produce errors of 4 ̊ to 5 ̊.

RDF stations normally know the sectors in which such

refraction may be expected. Such sectors may not be

included in the published sectors of calibration or may be

marked “sectors of uncertain calibration.”

SUNRISE, SUNSET, OR NIGHT EFFECTS: Be

obtained from about half an hour before sunset to 

half an hour after sunrise are occasionally unre

because of the polarization error introduced. Chan

the intensity of the signals received occur at sunse

sunrise.

CAUTION: When RDF stations use such wor

doubtful, approximate, second-class, or the equivale

foreign languages, the bearings reported must be t

with suspicion as considerable error may exist.

DANGER FROM RECIPROCAL BEARINGS: W

single station furnishes a bearing, there is a possibi

an error of approximately 180 ̊, as the operator 

station cannot always determine on which side o

station the ship lies. Certain direction finder sta

particularly those on islands or extended cape

equipped to furnish two corrected true bearings fo

observation. Such bearings may differ by approxim

180 ̊ and whichever bearing is suitable should be use

CAUTION: Mariners receiving bearings whic

evidently the approximate reciprocal of the c

bearings should never attempt to correct these bearin

applying a correction of 180 ̊, as such a correction 

not include the proper correction for deviation 

direction finder station. An error as large as 30 ̊ m

introduced by an arbitrary correction of 180 ̊. 

receiving bearings requiring an approximate 

correction should request both bearings from the dir

finder station.

100C. Obligations of Administrations Operating

Direction Finding Stations

The obligations of RDF station operators are giv

Article 35 of the manual for use by the Maritime M

Satellite Services of the International Telecommunic

Union (1992). They include the following:

– Effective and regular service should be maintaine

no responsibility is accepted for these services.

– Serviced stations shall be advised of doubtf

unreliable observations.

– RDF station operators shall make daily notificati

any temporary modifications or irregularities in se

Permanent modifications shall be published as so

possible in the relevant notices to mariners.

– All RDF stations shall be able to take bearings o

kHz and 500 kHz.

– When RDF service is provided in authorized 

between 1605 kHz and 2850 kHz, RDF st

providing that service should be able to take bearings on

2182 kHz.

– When RDF service is provided in the bands between 156

MHz and 174 MHz, the RDF station should be able to

take bearings on VHF 156.8 MHz and VHF digital

selective calling frequency 156.525 MHz.

100D. Procedure to Obtain Radio Direction

Finder Bearings and Positions

TO OBTAIN A BEARING: The vessel should call the

RDF station or the RDF control station on the designated

watch frequency. Depending on the type of information

wanted, the vessel should transmit the appropriate service

abbreviation(s):

– QTE: What is the true bearing from you (or designated

vessel)?

– QTH: Follows the above abbreviation when the request

is made to a mobile RDF station.

The vessel should also indicate the frequency it will use

to enable its bearing to be taken.

The RDF station called should request the vessel to

transmit for the bearing by means of the service

abbreviation QTG (Will you send two dashes of ten

seconds each (or carrier) followed by your call sign

(repeated __ times) on ___ kHz (or MHz)?).

After shifting, if necessary, to the new transmitting

frequency, the vessel should transmit as instructed by the

RDF station.

The RDF station should determine the direction, sense

(if possible), and classification of the bearing and transmit

to the vessel in the following order:

– QTE.

– Three digits indicating true bearing in degrees from the

RDF station.

– Class of bearing.

– Time of observation.

– If the RDF station is mobile, its own position p

by QTH.

When the vessel has received this information, i

repeat it back, if considered necessary for confir

The RDF station should confirm or correct the infor

When the RDF station is sure the information h

correctly received, it will transmit AR (e

transmission). The vessel will respond with AR.

Unless otherwise indicated, the vessel may assu

the sense of the bearing was indicated. If not, th

station should indicate this or report the bearing 

reciprocal.

CLASSSIFICATION OF BEARINGS: To estim

accuracy and determine the corresponding clas

bearing:

– An operator should generally, and particularly 

maritime mobile RDF service on frequencies belo

kHz, give the observational characteristics of b

shown in the table below.

– The RDF station, when facilities and time perm

take into account the probability of error in the b

A bearing is considered as belonging to a particu

if there is a probability of less than 1 in 20 

bearing error would exceed the numerical 

specified for that class in the table below

probability should be determined from an analys

five components that make up the total varianc

bearing (instrumental, site, propagation, 

sampling and observational components).

TO OBTAIN A POSITION (DETERMINED BY 

OR MORE RDF STATIONS ORGANIZED 

GROUP): The vessel should call the RDF control 

and transmit QTF (Will you give me my position ac

to the bearings taken by the RDF stations you contr

The control station shall reply and, when th

stations are ready, request that the vessel transmit u

service abbreviation QTG.

When the position has been determined, the control

station should transmit to the vessel:

– QTF.

– The position in latitude and longitude, or in relation to a

known geographic point.

– Class of position.

– Time of observation.

According to its estimate of the accuracy of the

observations, the control station shall classify the position

in one of the four following classes:

– Class A - positions which the operator may reasonably

expect to be accurate to within 5 nautical miles.

– Class B - positions which the operator may reasonably

expect to be accurate to within 20 nautical miles.

– Class C - positions which the operator may reasonably

expect to be accurate to within 50 nautical miles.

– Class D - positions which the operator may not expect to

be accurate to within 50 nautical miles.

For frequencies above 3000 kHz, where the distance

limits specified in the preceding subparagraph may not be

appropriate, the control station may classify the position in

accordance with current International Telecommunications

Union-Radiocommunications Sector (ITU-R)

recommendations.

TO OBTAIN SIMULTANEOUS BEARINGS FROM

TWO OR MORE RDF STATIONS ORGANIZED AS A

GROUP: On a request for bearings, the control station of a

group of RDF stations shall proceed as indicated above. It

then should transmit the bearings observed by each station

of the group, each bearing being preceded by the call sign

of the station which observed it.

100E. Plotting Radio Bearings

A fix by radio bearings is defined as follows:

– Three or more bearings taken simultaneously.

– Two bearings and a sounding.

– Two bearings and an LOP from a celestial body.

– Two bearings and a synchronized air or submarine

signal.

– Two bearings on the same station and the measure of

distance run (solve as if doubling the angle on the bow)

between bearings.

Radio bearings are great circle azimuths (the bearing is

the angle between the meridian of the ship or station taking

the bearing and the great circle, not the rhumb line). They

can be plotted directly upon gnomonic charts, but they

cannot be plotted on a Mercator chart without first being

corrected as described in sec. 100F.

WEIGHT TO BE GIVEN TO RADIO BEARINGS:

Before using a radio bearing for navigational purposes, the

mariner should consider the conditions under which it was

taken and should compare the conditions with those given

in sec. 100B on accuracy.

Land-based marine radiobeacon signals received by

ships may only provide a bearing accuracy relative to

vessel heading of ±3 ̊ - 10 ̊. This is not satisfactory for

navigation in restricted channels or harbors.

TRANSMITTERS AND RECEIVERS: Bearings

reported by a direction finding station ashore must be

plotted from the geographical position of the re

antenna of the station. Bearings taken by a ship on 

station must be plotted from the geographical pos

the station’s transmitting antenna.

CAUTION: These two positions are not the sam

stations.

SHIP’S PROBABLE POSITION: As radio bear

not absolutely accurate, lines should be drawn 

sides of each radio bearing at an angular distance f

bearing equal to the estimated probable error. In the 

intersecting radio bearings, the ship’s most p

position is the area enclosed by these outer lines.

In figure 1 the broken lines are radio bearings o

on a ship by three radio stations. The solid lines ar

at angles of 2 ̊ from the bearings (it is assumed tha

bearings are probably accurate within 2 ̊). Th

triangle in the illustration lies within the 2 ̊ erro

three bearings and is the most probable position 

ship. However, with the possibility that one of the b

may be off by more than 2 ̊, the areas shaded with 

lines give other possible positions. If one of the bea

suspected to be less accurate, the outer lines sh

offset from this bearing the same number of degree

estimated error, and the area or areas partially encl

these lines should be given less weight than the othe

In figure 2, a ship on course 000 ̊ obtains bea

031 ̊ and 065 ̊ on a radio station. The lines drawn 

dashes show the bearings and the continuous lines a

limits of accuracy. It is assumed that the bearings a

accurate within 2 ̊. The lines AB drawn with das

dots are equal to the distance run between bearin

distance run is fitted to the lines showing the li

accuracy of the bearings. This can be done easily by 

of parallel rulers and dividers. The shaded quad

shows the ship’s probable position at the time of the 

bearings, if both bearings are accurate within 2 ̊.

The table on pg. 1-7 may be used to convert r

great circle bearings into Mercator bearings for plo

a Mercator chart. The table should be used w

distance between the ship and station is over 50 mi

arguments used to find the correction are the 

latitude (Lm) and the difference of longitude 

between the position of the radio station and th

reckoning (DR) position of the vessel.

EXAMPLE: A vessel in DR position 56 ̊04'N, 14

To plot the bearing, add 180 ̊ to Mercator bearing, giving

110A. Coast and Port Radar Station List

Details concerning shore-based radar stations rendering

navigational assistance to ships on request are given in the

listings which follow. These stations are indicated on

charts by the abridged description: Ra.

These stations provide information of interest to the

mariner. They have a limited range of transmission and

usually broadcast traffic, navigational, weather and other

information concerning only their port limits and

approaches. The provision of such information does not

relieve the Master of his responsibility for t

navigation of his ship.

Mariners are warned that port radar station

suspend operation without notice for varying 

because of minor defects, maintenance work, etc.

Many of these stations provide radar informa

conjunction with Vessel Traffic Service (VTS) ope

In many ports participation in VTS may be compul

certain classes of vessels. For further information 

in specific ports, refer to National Ocean Servic

Pilots (NOSPBCP1 - 9), NGA Sailing Directions (

or CDPUBSD 120 - 200), and other applicable guid
