Why does owning a satellite constellation for refinery watch matter more than buying imagery from Planet, ICEYE, or Capella?

Commercial providers can reprioritise tasking, revoke access under pressure from their home government, or simply go out of business — any of which leaves your critical infrastructure blind at the worst moment. A sovereign constellation is always tasked at national priority, feeds data to nationally controlled ground infrastructure, and cannot be switched off by a foreign entity. The intelligence product stays inside your classification boundary from sensor to analyst.

What orbit and sensor type is best for watching a petrochemical complex?

LEO constellations between 450 km and 550 km altitude are optimal: they deliver sub-metre optical resolution and effective SAR coherent-change detection without the latency or cost of GEO. A mixed payload approach — optical for visual change detection and methane plume mapping, SAR for all-weather structural change and vehicle tracking — provides the most complete picture. Thermal infrared adds flare anomaly and hot-spot detection at minimal additional cost on the same platform.

How quickly can a satellite detect an unplanned shutdown or sabotage event at a refinery?

With a 16-satellite SAR constellation, mean revisit over a fixed site is approximately 90 minutes; with optical, this is weather-dependent but comparable on clear days. Thermal anomaly detection — the earliest indicator of an unplanned event — can flag a significant temperature deviation within one pass. Full confirmation via multi-modal analysis typically takes 2–4 hours from event onset to analyst-verified alert.

Can satellites detect methane and other toxic gas leaks from refineries?

Yes. Shortwave infrared (SWIR) spectrometers in LEO, such as those flown by GHGSat, can detect methane emissions above roughly 500 kg/hour from individual facilities. Nitrogen dioxide and sulphur dioxide plumes — indicators of process failure or deliberate sabotage — are detectable via hyperspectral payloads at similar sensitivity thresholds. This capability doubles as an environmental compliance tool, giving the sovereign operator regulatory leverage as well as security intelligence.

How does space-based refinery surveillance relate to ground-based perimeter security?

They are complementary layers in a defence-in-depth architecture. Satellite provides wide-area context, early-warning of approach vectors, and verification of ground sensor alerts — ground systems catch what satellites miss between passes. The most effective sovereign architectures integrate satellite change-detection alerts directly into the physical security information management (PSIM) platform at the facility, so operators see both layers on a single common operating picture.

What is the realistic cost of a sovereign microsatellite constellation for this mission?

A sovereign 12–16 microsatellite SAR constellation with a dedicated LEO ground station network and analytics platform typically costs $300–600 million to deploy over 5–7 years, based on comparable national programmes in Europe and Asia. Annual operations run $40–80 million. The cost is significant but is usually a rounding error against the value of the refining and petrochemical assets being protected, which frequently exceed $5–20 billion per major complex.

Are there international legal restrictions on using satellites to surveil refineries in other countries?

Under the UN Principles Relating to Remote Sensing of the Earth from Outer Space (UN GA Resolution 41/65, 1986), remote sensing from space is generally permissible under international law, including sensing of other states' territory. However, the resulting intelligence — particularly at sub-0.5 m resolution — may be subject to national export-control regimes in the satellite-operating state. A sovereign programme eliminates this dependency entirely and keeps intelligence under national legal jurisdiction.

How do we handle the data volume from a persistent watch constellation without drowning our analysts?

On-board AI-assisted change detection, deployed directly on the satellite processor, reduces downlinked data to anomaly-flagged chips rather than full-scene imagery. On the ground, automated multi-temporal comparison algorithms triage alerts by confidence score before they reach human analysts. This approach, used by BlackSky and Palantir in commercial contexts, typically reduces analyst review burden by 70–85% compared with raw imagery delivery, making a small sovereign intelligence team operationally viable.
