Maritime Mobile Traffic: Charges for Radio, Telex, and Satellite Services

Join Our Telegram (Seaman Community)

This is a guide to the costs associated with radiotelephone calls, including the conversion factor used for calculations. It also explains the pricing structure for radiotelegrams, covering aspects such as telephone radiotelegram and storage of telegrams and copies. Information on the costs associated with maintaining a radio log is also included, and covers the costs associated with MF and HF radiotelex, and telephone and telex services via Inmarsat-A/B and Inmarsat-C.

For practical application, the document includes a list of coast stations, specifically focusing on charges applicable in the United Kingdom, Germany, Australia, and South Africa. This information aims to provide a clear and accessible resource for mariners and maritime operators regarding communication cost considerations.

Radio telephone calls

The definition of a radiotelephone call is a call:

Charges for radio telephone calls

The charge for radio telephone calls consists of:

a Coast charge/land station charge – the charge for using the coast sta­tion involved in handling the traffic.

b Land line charge – the charge from the Using TELEX Over Radio: A Practical Guide for Exploitationcoast station to the subscriber.

c Charge for special services – like personal calls, collect calls, directory inquiries etc.

The coast charges differ with regard to the type of Inmarsat-A: Equipment, Procedures, and Distress Communicationradio communication equipment in use, such as DSC (Digital Selective Calling) Procedures for VHF – MF and HFVHF, MF and HF.

Conversion rate:

1 SDR = 3,061 Gfr.

The charges for the different coast stations can be found in the ITU publication “List of Coast Stations”, part IV.

The charges are quoted in SDR (Special Drawing Rights), or Gfr. (Gold Franc). SDR’s are convertible to all currencies by using the current rate between SDR and the currencies. This rate is fixed on a daily basis and is announced together with the exchange rate of other currencies.

In the following passage, we will study some examples to find out how the different charges are calculated:

Example I:

A radio telephone call from the “Berge Master”/LANO2, to a subscriber in Hamburg Germany, lasting 6 minutes. The call has taken place on HF via Nordeich Radio, Germany.

Charges:

You will find the charge for HF DSC – Digital Selective Callingradiotelephone calls in Part IV of the “List of Coast Stations”:

Calculation:

Land station charge = 3,0 SDR/min × 6 min = 18,00 SDR
Land line charge = 0,36 SDR/min × 6 min = 02,16 SDR
TOTAL = 20,16 SDR

Example II:

A radiotelephone call from the “Berge Master“/LANO2 to a subscriber in the U. K., lasting 6 minutes. The call has taken place on HF via Portishead Radio U. K. on a Sunday at 1225 local HF time (reduced rate).

Calculation:

Land station charge = 11,61 Fr/min × 6 min = 69,66 Fr
Land line charge = NO CHARGE = 0,00 Fr
TOTAL = 69,66 Fr

Radiotelegrams

Radiotelegrams are handed in at, or addressed to, a ship station, and are fully or partly sent via Maritime and Other Mobility Servicesmaritime mobile service radio communications. Radiotelegrams can be transmitted by telephony, telegraphy or by radio telex.

Radiotelegram charges are composed of:

a Basic charge (fixed charge) per telegram.

b Coast charge – the charge for the coast station involved.

c Land line charge -the charge from coast station to destination.

The charges can be found in the “List of Coast Stations”, and are normally quoted in SDR.

A radiotelegram is charged per word, counted from the addressee to the signature. Words not exceeding ten characters are counted as one charge able word, while words exceeding ten characters are counted at a rate of one chargeable word for each ten characters or part thereof.

Example III:

A radiotelegram from the “Berge Master“/LANO2, to “Ship’s Supplies, London”, sent via Portishead Radio by telephony:

Radiotelegram form
Radiotelegram form from Telenor to illustrate Example III

Calculation:

You will find the charges for the radiotelegram in the “List of Coast Sta­tions”.

Remember that charge rates are arrived at by counting each word from the addressee to the signature, regardless of whether the radiotelegram is sent by VHF, MF or HF telephony, TELEX (Narrow Band Direct Printing – NBDP) Procedurestelegraphy or radio telex.

Coast stn. charge = 20 words × 4,62 fr/word = 92,40 Fr
Land line charge = NO CHARGE = 0,00 Fr
TOTAL = 92,40 Fr

Example IV:

A radiotelegram from the “Berge Master”/LANO2 to addressee “Petrotex Rotterdam” sent via Nordeich Radio in Germany.

Radiotelegram Form Example IV
Radiotelegram Form from Telenor to illustrate Example IV

Calculation:

With reference to the “List of Coast Stations“, the charge will be as follows:

Coast stn. charge = 10 words × 0,38 SDR/word =3,80 SDR
Land line charge = Per block = 18,04 SDR
TOTAL = 21,84 SDR

Block = 20 words of max. 10 letters. The address is free of charge.

Telephoning a radiotelegram

When connection with a coast station has been established on a working channel, the telegram shall be sent in the following way:

From (ships name and call sign)
Number (radiotelegram number)
Number of words
Date
Time
AAIC (accounting code)
Addressee
Text
Signature (if applicable)

If the radiotelegram is received by the coast station, it will be acknowl­edged in the following way:

Berge Master
this is
Nordeich Radio
Your telegram number 2 is received.

Storage off Telegrams and Copies

All copies of radiotelegrams that have been sent and received shall be stored safely on board for a period of 6 months. Radiotelegrams older than 6 months may be discarded in a suitable manner. If the vessel is sold to a foreign country, laid up, or condemned, the telegram archives must be sent to the telecom administration.

Keeping a Radio Log

The radio log, as required by the SOLAS Convention, must be kept together with the radio and must be written in accordance with the details required by the Radio Regulations and guidelines.

All Regulations and Traffic Procedurestraffic concerning distress, urgency and safety correspondence is of vital importance.

Radio telex on the MF and HF bands

Telex messages are charged in the same way whether they are sent via Maritex or other coast stations.

Example V:

A radio telex message from the “Berge Master2“/LANO2, to a telex subscriber in London, via Portishead Radio U. K., transmitted on the 12 MHz band, duration 4,3 minutes.

With reference to the “List of Coast Stations”, part IV:

Calculation:

Land station charge = 4,3 min × 10,40 Fr = 44,72 Fr
Land line charge = 00,00 Fr
TOTAL = 44,72 Fr

Note: Remember the conversion rate for SDR to Gfr.

Example VI:

A radio telex message from the «Berge Master»/LANO2, to a telex subscriber in Rotterdam via Scheveningen Radio on HF, duration 4 minutes.

With reference to the “List of Coast Stations” part IV:

Calculation:

Land station charge = 4 min × 2,51 SDR/min = 10,04 SDR
Land line charge = 4 min × 0,06 SDR/min = 0,24 SDR
TOTAL = 10,28 SDR

Telephone and telex via Inmarsat-A/B

Telephone calls and telex messages transmitted via Inmarsat-A, are charged in periods of 6 seconds. (1 period = 6 seconds = 0,1 minute).

Below, a table of charges is shown for both telephone and telex messages via EIK LES, Norway. When using two-digit code (37 prefix) instead of the code for an automatic call (00), a short telex message containing the duration and call charges relating to the call will be received from the LES. Bear in mind that this service is not free of charge!

As a result of co-operation between the Norwegian Telecom, British Telecom and the Singapore Telecom, vessels from these countries are charged the same fees for all four ocean regions, when the traffic is routed via EIK, GOONHILLY or SINGAPORE LES.

Example VII:

A telephone call from “Berge Master”/LANO2 via EIK LES to a subscriber in London using Inmarsat-A, duration 4 minutes and 42 seconds. The charged duration will be 4,7 minutes (peak period).

Calculation:

  • $ – U. S. dollars
$6,55/min × 4,7 min = $30,78

Example VIII:

A telex message from the same vessel via Singapore LES to a telex subscriber in London using Inmarsat-A, duration 5,3 minutes.

Calculation:

$3,80/min × 5,3 min = $20,14

Land line charges from Singapore to UK are not calculated because the traffic is routed via Singapore LES. If another LES in the Pacific ocean region had been used, land line charges would have been added to the sum.

Inmarsat-C Charges

Inmarsat-C system charges are largely based on two main elements plus AA surcharge (Accounting Authority/Billing Entity, adding charges for administration service).

a Service charge – charge for the means of communication in use, also including the use of Inmarsat space segments.

b Land line charge – the charge for transmitting the message via the national/international telecom network to the destination.

c AA surcharge.

The LES (land earth stations) generally applies a SERVICE CHARGE for a store and forward telex per kilobit, or quarter of a kilobit.

  • 1 kilobit = 1 024 bits
  • 1/4 kilobit = 256 bits

On board the ship, the size of the message is given on the Inmarsat-C screen as a number of bits or as a number of characters/bytes.

The different units are defined as such:

1 character = 1 byte = 8 bits.
1 kilobit = 1 024 bits = 128 bytes/characters.

To find out which method of calculation a LES is using, one must contact the LES Customer Service Point. (Ref. Inmarsat-C User’s Manual).

Example IX:

A standard 7 bits telex message store-and-forward to Norway via Eik LES, consisting of 400 characters.

Eik LES is charging per quarter of a kilobit (256 bits). The charge is $0,23 per unit.

Conversion formula:

Charging blocks = number of characters × bits per char. 256

Note: The number of blocks must be rounded off to the next whole number.

Calculation:

400 characters × 8256 = 12,5 round off to 13
Charge = $ 0,23 × 13 = $2,99 

The same message sent as 5 bit packed Baudot:

400 characters × 5256 = 7,81 round to 8
Charge = $ 0,23 × 8 = $1,84 

When routing a message to a destination outside the LES’ country, land line charge will be added.
