Full title and description

St ISO 17854-2013 — Space data and information transfer systems — Flexible advanced coding and modulation scheme for high rate telemetry applications. This International Standard specifies a turbo-like Serial Concatenated Convolutional Code (SCCC) based coding and modulation approach, together with recommended modulation formats and framing/synchronization arrangements, intended to increase throughput and robustness for high‑rate satellite telemetry links (for example Earth Exploration Satellite Service telemetry payloads).

Abstract

ISO 17854:2013 defines an efficient, flexible coding-and-modulation solution able to support a wide range of spectral efficiencies and data rates for high‑rate telemetry. It presents a pragmatic bit‑interleaved coded‑modulation approach using a serially concatenated convolutional code (SCCC) combined with a family of modulation options (QPSK, 8PSK, 16APSK, 32APSK, 64APSK) and a set of coding rates. The scheme supports Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM) operation modes, specifies a constant‑length physical‑layer frame with fixed pilot positions to simplify synchronization, and gives recommended pairings of modulation formats and coding/synchronization implementations for telemetry applications.

Scope

This standard specifies a flexible coding and modulation framework for high‑rate telemetry applications, primarily aimed at satellite telemetry (for example Earth Exploration Satellite Service payloads). It defines the SCCC‑based forward error correction approach, mapping of binary encoder outputs to a range of modulation formats, optional use of VCM and ACM operational modes, a constant physical‑layer frame structure including pilots for synchronization, and recommended format pairings that combine modulation, coding rate and synchronization methods. The standard is intended to increase spectral efficiency and throughput while maintaining practical synchronisation and acquisition for very high data‑rate receivers.

Key topics and requirements

• Serial Concatenated Convolutional Code (SCCC) — a turbo‑like concatenation of two simple four‑state encoders as the FEC basis.
• Bit‑interleaved coded modulation: pragmatic mapping of encoder outputs to modulation symbols.
• Supported modulation formats: QPSK, 8PSK, 16APSK, 32APSK, 64APSK (recommended family).
• Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM) operation modes to match channel conditions.
• Constant‑length physical‑layer frames with pilots in fixed positions to simplify synchronization and fast acquisition at high rates.
• Recommended format tables pairing modulation, coding rate and synchronization/implementation options for telemetry links.
• Focus on high throughput and spectral efficiency for Earth observation and other high‑data‑rate satellite telemetry services.

Typical use and users

Primary users are satellite communications engineers, spacecraft telemetry subsystem designers, ground station modem manufacturers, mission systems integrators, and researchers developing high‑rate telemetry links. Typical uses include specification of onboard telemetry transmitters and ground receivers, selection of modulation/coding strategies for mission planning, and interoperability guidance where higher spectral efficiency and adaptive transmission are required.

Related standards

Closely related materials include other ISO and IEC standards addressing space data and information transfer systems and technical recommendations from the Consultative Committee for Space Data Systems (CCSDS) on coding, modulation, telemetry and telecommand. National adoptions (for example published as a national standard or a “BS ISO …” designation) and other ISO space‑communications deliverables produced by ISO/TC 20/SC 13 are also relevant when implementing or integrating this standard.

FAQ

Q: What is this standard?

A: ISO 17854:2013 is an International Standard that defines a flexible coding-and-modulation scheme (SCCC-based, bit‑interleaved coded modulation) for high‑rate satellite telemetry applications.

Q: What does it cover?

A: It covers the coding structure (serial concatenated convolutional coding), supported modulation formats, framing and pilot arrangements for synchronization, and operational modes (VCM and ACM) to adapt transmission to changing channel conditions. The standard also provides recommended pairings of modulation and coding implementations for telemetry links.

Q: Who typically uses it?

A: Satellite communications engineers, spacecraft and payload designers, ground station/modem manufacturers, systems integrators and researchers working on high‑throughput telemetry links and Earth‑observation payload data downlink systems.

Q: Is it current or superseded?

A: ISO 17854:2013 was published on 30 June 2013 (Edition 1). It is a published International Standard and is subject to ISO's periodic review cycle. There is no widely published superseding version of ISO 17854 as of the publication date of this product page; users should verify the current ISO catalogue or national standards body listing for the latest lifecycle status before procurement or normative referencing.

Q: Is it part of a series?

A: The standard sits within ISO's space data and information transfer systems portfolio (ICS 49.140) and is produced by ISO/TC 20/SC 13. It complements CCSDS recommendations and other ISO space communications standards rather than being a numbered multi‑part series itself.

Q: What are the key keywords?

A: telemetry, space communications, SCCC, coded modulation, VCM, ACM, forward error correction, synchronization, modulation formats, high‑rate telemetry.
