BS EN 16603-50-04:2014

What is BS EN 16603-50-04 - Telecommand protocols, synchronization, and channel coding about?

BS EN 16603-50-04 specifies the data structures and protocols for a telecommand space data link and the procedure for physical layer operation.

Usually, the source of data on a telecommand space data link is located on the ground and the receiver is located in space. However, BS EN 16603-50-04 may also be used for space-to-space telecommand data links.

Further provisions and guidance on the application of BS EN 16603-50-04 can be found, respectively, in the following documents:

• The higher-level standard ECSS-E-ST-50 “Communications”, defines the principal characteristics of communication protocols and related services for all communication layers relevant for space communication (physical- to application-layer), and their basic relationship to each other.
• The handbook ECSS-E-HB-50 “Communications guidelines”, provides information about specific implementation characteristics of these protocols to support the choice of a certain communications profile for the specific requirements of a space mission.

Users of BS EN 16603-50-04 are invited to consult these documents before making decisions on the implementation of the present one.

Who is BS EN 16603-50-04 - Telecommand protocols, synchronization, and channel coding for?

BS EN 16603-50-04 on telecommand protocols, synchronization, and channel coding is relevant to:

• Space product manufacturers
• Design engineers
• Space project managers
• Quality compliance personnel

Why should you use BS EN 16603-50-04 - Telecommand protocols, synchronization, and channel coding?

BS EN 16603-50-04 describes the data structures and protocols used in space missions to transmit data on telecommand space data links. BS EN 16603-50-04 is designed to meet the requirements of space missions for the reliable transfer of telecommands over ground-to-space or space-to-space communications links.

Guidelines under BS EN 16603-50-04 assist you in demonstrating the sublayers of the data link layer such as the segmentation sublayer, the transfer sublayer, and the synchronization and channel coding sublayer.

BS EN 16603-50-04 also provides you with a means for transferring data units on behalf of higher layers.
