Broadcast.

 The Inmarsat-C network is a Store-and-Forward system. This means that when a message is sent, it is stored within the system until the message is sent to the last destination. The message can be sent to several addresses simultaneously. (Multidracking, Maximum - 10).

Addressees

The table shows the destinations that can be reached from your mobile installation. Not all Earth Stations serve all types, as only Telex and the mobile Inmarsat-C are mandatory. The addresses of various types of destinations are fully described in the subject Address book Capsat 

Reproduction.

The message can be sent in three formats known as 5, 7 and 8-bit playback.

5 bits   Known as Baudot or Telex playback (ITA2). Reduces

transmission costs, about 33%, but only Telex signs will be accurately transmitted.

7 bits   Supported by all Earth Stations and is also known as

reproduction ASCII. All signs represented by values ​​from 0 to 127 will be accurately sent to Earth Stations. Values ​​greater than 127 will be cropped.

8 bits   Known as data. All signs are transmitted over satellite communication

exactly. When you receive a message at the Earth Station, it will also be accepted accurately.

Note. Some Earth Stations insert a header in the message, which the recipient must delete before using the message, for example, if the message was a spreadsheet data file.
