Full title and description

Space data and information transfer systems — CCSDS Space Link Protocols over ETSI DVB‑S2 Standard. This International Standard defines an adaptation profile for using the ETSI DVB‑S2 satellite broadcast standard to transport CCSDS transfer frames for telemetry and related space‑to‑ground links, including the interface mechanisms (ASM/CADU) and recommended DVB‑S2 options for high‑data‑rate telemetry applications.

Abstract

The standard describes how DVB‑S2 modulation and coding modes (QPSK, 8PSK, 16APSK, 32APSK and LDPC coding) can be used to maximise telemetry throughput and how to map CCSDS transfer frames into DVB‑S2 Channel Access Data Units (CADUs). It specifies CADU stream generation, DVB‑S2 transmission options, managed parameters and normative service definitions, and discusses security/patent considerations in informative annexes.

Scope

Specifies an adaptation profile that maps CCSDS Transfer Frames and the CCSDS space link protocol functions onto the ETSI DVB‑S2 physical and synchronization constructs for telemetry use. It is intended for use where DVB‑S2 is selected as the waveform for space‑to‑ground (and similar) links and covers CADU stream generation, DVB‑S2 transmission parameters, managed parameters and service definitions needed to ensure interoperability between CCSDS elements and DVB‑S2 equipment. The standard treats DVB‑S2 as a self‑contained transport and notes that DVB‑S2 features are only applicable within the profile context.

Key topics and requirements

• Mapping of CCSDS Transfer Frames into DVB‑S2 CADUs and the use of Attached Synchronization Marker (ASM) for the interface.
• Recommended DVB‑S2 modulation and coding schemes (QPSK, 8PSK, 16APSK, 32APSK; LDPC codes) and guidance on VCM/ACM use for variable link conditions.
• Definition of managed parameters and parameters' ranges/options required for interoperable telemetry links.
• Normative service definition for telemetry over DVB‑S2 and informative annexes covering security, patent considerations and terminology.
• Implementation notes to facilitate reuse of telecom DVB‑S2 receiver modules, VHDL IP cores and ASICs where beneficial for ground or flight segments.

Typical use and users

Used by space agencies, satellite ground segment designers, mission system engineers, RF and telemetry subsystem contractors, spacecraft manufacturers and standards developers implementing or procuring high‑throughput telemetry links that rely on DVB‑S2 waveforms. It is also referenced by CCSDS working groups and national standards bodies when defining space‑to‑ground transport profiles.

Related standards

Closely related to CCSDS Space Link protocol documents and a range of ISO/CCSDS standards on space data and mission operations (for example other ISO 202xx series items published in 2015). Implementers often consult the original DVB‑S2 specification (ETSI) and CCSDS recommendations for synchronization and channel coding when applying this profile. National adoptions (e.g. BS ISO 20207:2015) provide the same technical content in national catalogues.

FAQ

Q: What is this standard?

A: ISO 20207:2015 is an International Standard that defines how to use the ETSI DVB‑S2 satellite broadcast standard to carry CCSDS space link telemetry (mapping CCSDS transfer frames into DVB‑S2 CADUs and related interface definitions).

Q: What does it cover?

A: It covers CADU stream generation, DVB‑S2 transmission options and parameters, recommended modulation/coding choices for telemetry, managed parameters, a normative service definition and informative annexes on security and terminology — i.e., the adaptation profile needed to ensure interoperability between CCSDS protocols and DVB‑S2 implementations.

Q: Who typically uses it?

A: Space agencies, satellite ground segment and RF/telemetry engineers, spacecraft prime contractors and organisations implementing CCSDS‑based telemetry over DVB‑S2. Standards developers and test laboratories also use it for conformance guidance.

Q: Is it current or superseded?

A: ISO 20207:2015 is the published ISO edition from 2015. Users should check national standards bodies or CCSDS updates for any newer CCSDS recommended practices or later ISO revisions; as of the ISO publication record the 2015 edition is the issued International Standard.

Q: Is it part of a series?

A: Yes — it is part of a sequence of ISO/CCSDS space data and information transfer systems publications (the ISO 202xx family produced in the same timeframe covers related CCSDS topics and mission‑operations interfaces). Implementers commonly reference adjacent ISO 2020x standards and CCSDS documents for complementary functions.

Q: What are the key keywords?

A: Key keywords include: CCSDS, DVB‑S2, telemetry, CADU, ASM, modulation, LDPC, VCM/ACM, space link, space data transfer.
