ISO 26868:2009 establishes a data compression algorithm applicable to two-dimensional digital spatial image data from payload instruments and specifies how this compressed data is formatted into segments to enable decompression at the receiving end. Source coding for data compression is a method utilized in data systems to reduce the volume of digital data to achieve benefits in areas including, but not limited to: reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; reduction of data-transmission time at a given rate.

Overview

ISO 26868:2009 - "Space data and information transfer systems - Image data compression" specifies a standardized data compression algorithm and a segment-formatting method for two‑dimensional digital spatial image data produced by spacecraft payload instruments. Adopted from CCSDS 122.0‑B‑1, the standard targets efficient source coding to reduce transmission channel bandwidth, buffer and storage requirements, and data‑transmission time while ensuring reliable decompression on the receiving end.

Key Topics and Requirements

Scope: Compression for two‑dimensional spatial image data from payload instruments (satellite and spaceborne sensors).

Core algorithm elements:

Discrete Wavelet Transform (DWT) for multi‑level decomposition of images into subbands (low/high frequency components).
Bit Plane Encoder (BPE) for entropy coding across bit planes, including provisions for initial DC coefficient coding and AC bit‑depth specification per block.

Segment formatting:

Compressed data is organized into segments with defined header parts to enable proper decoding and error resilience.
Header fields cover image/frame parameters, DWT levels, subband weights, and coding parameters required for decompression.

Practical constraints:

Reduces channel bandwidth, buffering and storage needs, and overall transmission time.
Includes guidance on coding stages, symbol nomenclature and security considerations relevant to space data systems.

Interoperability:

Based on CCSDS Recommended Standard; designed for adoption across international space agencies and ground systems to ensure compatibility.

Applications and Who Uses It

ISO 26868 is relevant to organizations and professionals involved in:

Satellite and spacecraft mission design - mission planners selecting onboard compression to meet telemetry budgets.

Payload instrument teams - designers of optical, multispectral, hyperspectral, or imaging radar instruments needing onboard image compression.

Ground segment and data processing - system integrators and software developers implementing decompression, archiving, and distribution pipelines.

Remote sensing and Earth observation - agencies and commercial providers handling large volumes of imagery where bandwidth and storage are constraints.

Planetary and astronomical missions - where long‑distance telemetry links make efficient compression essential.

Benefits include predictable, interoperable compressed image streams that minimize telemetry costs while enabling accurate reconstruction on the ground.
