Data coverage // Constellation status
The Spica constellation revisits 94% of Earth's landmass every four hours at 0.7 m native resolution. Every pass is routed through the Insight pipeline and delivered as analysis-ready change-detection tiles — typically within 78 minutes of acquisition.
Bringing an area of interest? Mission ops can confirm the next pass window before the call.
Datasheet // Coverage axes
Every coverage claim below resolves to a number a GIS engineer can paste into a tender response. No adjectives, no qualifiers — just the axes that determine whether the constellation actually services your area of interest.
0.7 m
Sub-meter ground sample distance at nadir, with sharpening on the 0.5 m panchromatic band. Sufficient to distinguish individual vehicles, vessel wakes, and small-scale encroachment on linear infrastructure.
4 hmedian
Median time between successive cloud-free opportunities across 94% of Earth's landmass. Worst-case revisit at the equator remains inside 11 hours; high-latitude AOI typically sees six or more passes per day.
78 minmedian
Wall-clock time from a confirmed tasking request to an analyzed tile landing in your S3 bucket, GCS bucket, or Spica Insight workspace. Independently benchmarked by the Open Geospatial Consortium in Q1 2025.
94%of land
Routine revisit coverage spans every inhabited continent, with the residual 6% concentrated in polar regions and the open Southern Ocean — areas addressable through partner constellations on a 24-hour SLA.
How the revisit actually holds up
Spica operates 11 satellites distributed across three orbital planes at 528 km sun-synchronous altitude. Two planes are dedicated to mid-latitude tasking; a third plane carries a dawn-dusk local-time crossing to maintain cadence during eclipse season. Phasing is reviewed quarterly against the published acquisition ledger — we do not move the satellites for marketing screenshots.
The cadence contract is published, not estimated. Every acquisition is timestamped to the millisecond in the open ledger, and every delivered tile carries a verifiable acquisition-to-delivery signature. Procurement teams can audit the latency numbers against their own integration tests during evaluation.
Regional readout
Median figures measured across the trailing 90 days. Cloud-cover strategy reflects the dominant seasonal pattern for that region — every account is supported by a dedicated mission planner who can confirm a specific AOI's window.
Coastal California, Gulf Coast, and the agricultural Midwest see additional passes under the tasking-priority tier.
Amazon basin and Andean cloud forests reconciled through stacked-pass change detection with sub-pixel registration.
Saharan dust and Mediterranean haze flagged at acquisition; aerosol-corrected tiles ship with a per-pixel confidence band.
Singapore mission ops handles tasking 24/7; typhoon-season acquisition windows are pre-allocated to subscribing customers.
Harmattan haze and ITCZ cloud bands handled via composite-pass scheduling; published partnership with the World Bank on forest-loss monitoring.
Great Barrier Reef bleaching monitoring and Pacific maritime domain awareness tasks share a high-cadence maritime tier.
