Space data is exploding—more smallsats, more sensors, more passes. The winners aren’t just launching; they’re turning raw telemetry and pixels into timely, trusted decisions. SaaS provides a cloud control plane for mission ops, tasking, ground scheduling, ingestion, processing, cataloging, analysis, and delivery—paired with edge preprocessing at ground stations to cut latency and cost. Standardized formats (STAC/COG), event-driven pipelines, and built‑in ML let teams move from downlink to insight in minutes with strong governance, security, and predictable economics.
- End‑to‑end reference architecture
- Space segment
- Satellites with payload and TT&C; on‑board compression, windowing, and lightweight scene detection to prioritize downlink.
- Ground segment
- Multi‑ground‑station scheduling; antenna/receiver control; forward error correction; edge preprocessing (decompression, radiometric correction stubs, quicklooks).
- Cloud control plane (SaaS)
- Tasking and access; pass prediction and scheduling; telemetry ingest; event bus; processing pipelines; catalog and search; user apps and APIs; billing and audit logs.
- Ingest and processing pipelines (minutes, not days)
- Streaming ingest
- As soon as frames arrive: validate, assemble, de‑dupe, and checksum; attach orbit metadata (TLE/ephemeris) and quality flags.
- Sensor‑aware processing
- EO: radiometric/atmospheric correction, ortho/terrain correction (DEM), pansharpening, cloud/shadow masks.
- SAR: focusing (Range‑Doppler/ω‑κ), speckle filtering, geocoding, terrain correction, coherence, and interferometry prep.
- Hyperspectral: smile/keystone correction, atmospheric compensation, spectral indices, and dimensionality reduction.
- Formats that scale
- Cloud‑Optimized GeoTIFF (COG) for imagery; Zarr/Parquet for cubes/arrays; STAC items/collections with assets and links; SpatioTemporal tiling for fast map rendering.
- Catalog, discovery, and access
- STAC‑native catalog
- Collections by sensor/platform; items with geometry, datetime, processing level, QA, and licensing; assets with media types and COG tiling hints.
- Search and subscriptions
- Spatial/temporal queries, filters (cloud %/incidence angle), AOI watchlists, and event subscriptions (new scene over AOI triggers pipeline/notification).
- Delivery options
- Tiled web maps, direct signed URLs, partial reads via Range/COG, and bulk exports; delta updates and change feeds.
- Tasking, scheduling, and SLAs
- Tasking UI/API
- Define AOIs, windows, priority, off‑nadir, polarization/band sets, and constraints; quote feasibility and price before commit.
- Multi‑ground‑station orchestration
- Automatic pass selection across networks; conflict resolution; failover to alternate sites; edge‑to‑cloud transfer acceleration.
- SLA management
- Contracted latency (e.g., <30min from overpass), coverage %, and quality thresholds; credits for misses; operational dashboards.
- ML and analytics built‑in (with guardrails)
- On‑demand inference
- Ship detector/segmenter models (ships, aircraft, roads, deforestation, floods, illegal mining) as serverless jobs; batch over historical backfills.
- SAR/EO analytics
- Coherence change for infrastructure monitoring; water extent, burn scars, NDVI anomalies, building footprints.
- Evaluation and provenance
- Model cards, training data lineage, accuracy/precision metrics per biome/region; versioned results with confidence maps; “receipts” for each inference.
- Data fusion and time‑series intelligence
- Multi‑sensor fusion
- EO + SAR + thermal + AIS/ADS‑B + weather + DEM; align in a common grid/projection; uncertainty propagation.
- Change detection and alerts
- Persistent time‑series over AOIs; baselines and thresholds; event rules trigger notifications, workflows, or integrations (e.g., task a revisit).
- Integration with downstream systems
- Webhooks and APIs to push results to GIS, asset management, insurance claims, ag platforms, defense COPs, and BI tools.
- Performance, cost, and carbon discipline
- Egress control
- Keep heavy processing near storage; use COG partial reads and on‑the‑fly tiling; cache tiles and derived products; compress with ZSTD/Deflate.
- Intelligent placement
- Route batch processing to low‑cost/low‑carbon regions; prioritize GPU where ML density is high; pre‑warm serverless for critical SLAs.
- Unit economics
- $/scene, $/km², $/GB processed/served, $/inference; Wh/GB and gCO2e/GB metrics; budgets/alerts and soft caps for tenants.
- Security, sovereignty, and trust
- Zero‑trust identity
- SSO/MFA/passkeys; attribute‑based access by tenant, program, clearance, and AOI; just‑in‑time elevation.
- Data controls
- Region pinning and project‑scoped buckets; per‑tenant encryption (BYOK/HYOK); audit logs for every access/export; watermarking of derivative products.
- Compliance
- ITAR/EAR awareness, remote‑sensing regulations by country, data masking/redaction where policy requires; incident response and evidence packs for audits.
- Reliability and operations at scale
- Resilience
- Store‑and‑forward at ground; retry/backoff; multi‑region replicas for catalogs, not for restricted imagery unless policy allows.
- Observability
- Per‑pass ingest stats, pipeline success/latency, tile cache hit rates, model run metrics; on‑call with runbooks and gamedays.
- OTA and config management
- Signed firmware/configs for ground gear; versioned processing chains; canary rollouts and instant rollback.
- Developer experience and extensibility
- APIs and SDKs
- STAC/OGC APIs with OpenAPI specs; signed URL helpers; Python/JS SDKs; sample notebooks and reference pipelines.
- Serverless operators
- Drop‑in steps for common corrections, tiling, and models; custom WASM/GPU kernels pluggable with contracts and tests.
- Marketplace
- Third‑party models (e.g., building extraction), premium DEM/weather layers, and domain apps (ag, maritime, insurance) with revenue share.
- Sector playbooks (examples)
- Agriculture
- Field boundaries ingestion; cloud‑masked NDVI/NDRE, evapotranspiration estimates, variable‑rate maps; alerts for stress and storms; integrate to agronomy tools.
- Disaster and public safety
- Flood/wildfire extent maps within minutes; damage grading; road accessibility; push to emergency COPs and public dashboards with confidence.
- Infrastructure and energy
- Linear asset monitoring (pipelines, rails, transmission); vegetation encroachment; land movement via InSAR; compliance reports with geotagged evidence.
- Maritime
- SAR+AIS dark vessel detection; port congestion; illegal fishing patterns; handoffs to enforcement tasking.
- Insurance and finance
- Property condition and change scores; construction progress; catastrophe footprints; portfolio risk dashboards.
- Pricing and packaging
- Meters
- Tasking (km² or scenes), storage, processing jobs (per GB/minute), inferences (per km²/object), and data egress; pooled credits and volume tiers.
- SKUs
- Capture (tasking & scheduling), Process (pipelines & ML), Catalog (storage & search), Deliver (tiling & APIs), and Enterprise (BYOK/residency, private networking, SLA).
- Cost transparency
- Quotes before tasking/processing; forecasts and thresholds; SLO credits for latency/quality misses; monthly “value receipts.”
- 30–60–90 day rollout blueprint
- Days 0–30: Stand up STAC catalog and COG tiling; connect one ground station feed (or sample data); build an ingest→process→tile pipeline for a single sensor; enable SSO/MFA and project scoping; ship a basic AOI search UI and signed URL delivery.
- Days 31–60: Add tasking feasibility API and pass predictions; integrate a second sensor (e.g., SAR) with core corrections; launch one ML inference (cloud mask or building footprints) with evaluation metrics; add budgets/alerts and per‑tenant dashboards.
- Days 61–90: Introduce event subscriptions and AOI watchlists; enable BYOK/residency for restricted programs; optimize costs with COG reads and caching; publish SDKs and sample notebooks; run a disaster response drill and issue the first “space receipts” (latency, coverage, accuracy, $/km²).
- Common pitfalls (and fixes)
- Proprietary formats and lock‑in
- Fix: adopt STAC/COG/Zarr; document schemas; provide bulk export and exit SLAs.
- Latency and egress blowups
- Fix: edge preprocessing, partial reads, tile caches, and compute‑near‑data; schedule heavy jobs smartly.
- “Model theater”
- Fix: publish evals, confidence maps, and limits; keep humans in the loop for high‑impact decisions.
- Compliance surprises
- Fix: region pinning, BYOK/HYOK, license tagging, and country‑specific policy enforcement; log every access.
- Fragile ground→cloud handoffs
- Fix: robust store‑and‑forward, checksums, retries, and health probes; multiple ground sites and link failovers.
