E02Data storage

Store mission data, software, and telemetry.

Manufacturers & products

Recorders buffer payload and housekeeping data until transmission. Complete mass-memory/data-handling units, hosted solid-state drives and raw memory boards have different integration requirements and are labeled accordingly.

These are sourcing candidates, not a confirmed Starlink supply chain.

manufacturer

AAC Clyde Space

Sirius TCM LEON3FT

Telemetry and mass-memory module with protected storage, processing and spacecraft data interfaces. [1]

Manufacturer inquiry

Official supplier inquiry or custom-program discussion; confirm the delivered configuration, qualification, price and schedule. No inventory or lead-time claim is inferred.

Product scope & qualifications

Does not include the external RF transmitter; command/data handling and radio hardware are separate.

Durango 3U / 6U memory boards and SSR integration

SpaceVPX flash-memory boards can be combined with processing and system hardware into a scalable solid-state recorder. [5]

Manufacturer inquiry

Official supplier inquiry or custom-program discussion; confirm the delivered configuration, qualification, price and schedule. No inventory or lead-time claim is inferred.

Product scope & qualifications

Board capacities are in terabits, not terabytes; a memory board alone is not a complete enclosed recorder.

manufacturer

DSI Aerospace

Payload data handling units / mass memory

Custom payload data-handling units integrate mass memory with processing and telemetry functions for spacecraft programs. [6]

Custom program inquiry

Official supplier inquiry or custom-program discussion; confirm the delivered configuration, qualification, price and schedule. No inventory or lead-time claim is inferred.

Product scope & qualifications

manufacturer

AROBS Polska

Flash Mass Memory module

Flash mass-memory modules supplied for payload-computer integration, with file and memory-management functions assigned at system level. [7]

Company location: Poland

Custom program inquiry

Official supplier inquiry or custom-program discussion; confirm the delivered configuration, qualification, price and schedule. No inventory or lead-time claim is inferred.

Product scope & qualifications

Module requires a higher-level controller for file management, bad blocks and wear leveling.
Formerly SYDERAL Polska; FMM is presented as an ESA collaboration and customizable module offering, not a stocked standard recorder.

manufacturer

SEAKR Engineering

Solid-state recorders / Mod-Mesh data management

Custom solid-state recorders and memory/data-management equipment, with the manufacturer documenting program-specific deliveries including the JWST recorder. [9]

Company location: United States

Custom program inquiry

Official supplier inquiry or custom-program discussion; confirm the delivered configuration, qualification, price and schedule. No inventory or lead-time claim is inferred.

Product scope & qualifications

Historical mission hardware demonstrates supplier capability but is not an off-the-shelf configuration or the modeled satellite BOM.
The earlier technology page has moved. Follow the manufacturer website for current memory-system offerings and configuration inquiries.

What remains unverified

Mercury RH3480 public materials have inconsistent throughput units; no throughput number is carried into this catalog.
Custom Airbus, DSI and SEAKR recorder configurations do not expose a complete current public price/performance matrix.
Public memory-development programs are not counted as ready-to-order flight recorders.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Usable capacity · Gbit; Tbit; GB; TB
Preserve bits versus bytes, raw versus ECC-protected capacity, and beginning- versus end-of-life guarantees.
Sustained data rates · Mbit/s; Gbit/s; MB/s
Compare recording while reading, scrubbing and correcting errors; interface line rate is not sustained application throughput.
Endurance and retention
Check write cycles, retention at temperature and life-long bad-block allowance for the actual duty cycle.
Radiation error behavior
Ask for ECC strength, SEFI recovery, scrub strategy and data loss during resets or power interruptions.
File and memory management
Identify which controller handles wear leveling, bad blocks, files, packet indexing and telemetry formatting.
Interface and redundancy
Confirm host protocol, dual-port access, routing and independent power/control paths.
Complete assembly budget · W; kg; mm
Include controller, boards, enclosure, power converters and cooling in SWaP.
Qualification and delivery boundary
Differentiate engineering models, flight boards and qualified complete recorders; request exact configuration control.

Selection & integration notes

A memory board may require an OBC or payload processor to create a complete recorder.
Do not compare Tbit capacity directly with TB; preserve the source unit.
Storage attached to a flight-proven processor does not automatically inherit the processor flight qualification.
