Now live with Sentinel-2, Landsat, and Planetary Computer

The Operating System for Earth Observation Data

ASTRA OS unifies satellite imagery from multiple providers into a single, developer-friendly API. One search, one format, one invoice.

Live Demo

Search satellite imagery in real time

Pick a location, enter coordinates, or explore historical events — see real results from Sentinel-2, Landsat, and Planetary Computer through one unified API.

The Problem

Satellite data integration is broken

Every company building on satellite data reinvents the same infrastructure. ASTRA OS eliminates this work entirely.

Format Fragmentation

Sentinel uses SAFE, Planet delivers GeoTIFF, Maxar uses NITF, SAR data comes in complex phase formats.

We standardize everything to COG + STAC

Resolution Mismatch

Sentinel-2 at 10m, Planet at 3m, Maxar at 30cm. Fusing these requires significant preprocessing.

Common grid with scale= and resampling= params

Procurement Complexity

Managing separate contracts, billing systems, and SLAs with each provider.

One API key, one invoice

Processing Overhead

Cloud masking, atmospheric correction, and co-registration consume 40-60% of engineering time.

Callable primitives: ndvi(), change_detection()

No Unified Search

No single interface to discover what imagery exists across all providers.

One search across all providers

Developer Experience

Integrate in minutes, not weeks

A clean, consistent API that works the same way regardless of which satellite provider the data comes from. Get your first results in 5 lines of code.

Use Cases

Built for teams that need satellite data

From climate tech startups to agricultural analytics to insurance risk assessment.

Climate Tech Startup

The Problem

Can't unify Sentinel + Landsat quickly. Engineers spend weeks writing custom ETL pipelines for each provider.

With ASTRA OS

One search → one API → done. Query both providers with a single request, get normalized COG output.

Days of integration become one afternoon.

Agricultural Analytics

The Problem

Need frequent optical imagery + historical data for crop monitoring and yield prediction.

With ASTRA OS

Sentinel-2 for current 5-day revisit + Landsat archive for 40-year trend analysis. Unified time series through one API.

Seamless multi-source time series without data engineering.

Insurance / Risk Assessment

The Problem

Fragmented data access, manual discovery across providers. Slow underwriting analysis.

With ASTRA OS

Centralized catalog + consistent metadata. Search any AOI, get all available imagery ranked by relevance.

Faster underwriting with automated imagery discovery.
