Illegal mining and logging enforcement

Illegal extraction outpaces ground enforcement by design. Space-based alert systems change that calculus by delivering clearing, road and sediment signatures within hours, not after the damage is irreversible.

The dependence this ends: Enforcement that arrives after the forest is gone

Why enforcement fails without persistent eyes overhead

Illegal logging and alluvial mining share one operational logic: move fast, extract value, and disappear before anyone with authority arrives. Ground patrols cover perhaps a few hundred square kilometres per week in difficult terrain. A chainsaw crew can clear several hectares overnight. By the time a ranger reaches the site, the timber is already on a truck and the concession boundary has been redrawn by fait accompli. The enforcement gap is not a resource problem alone. It is a geometry problem.

Commercial satellite imagery has existed for decades, but purchasing archive scenes after the fact is not enforcement. It is archaeology. What changes the equation is systematic, near-daily revisit with automated change detection: an alert that reaches an enforcement officer while the road is still being cut, not six weeks later when a researcher flags the anomaly in a published paper. Several Amazon-basin jurisdictions have demonstrated that alert latency below 48 hours correlates with a measurable increase in interception rates. The physics of cloud cover, orbit mechanics and sensor choice determine whether that latency is achievable over a specific territory, and those constraints deserve honest treatment before any programme is designed.

What the sensors actually see, and what they cannot

Multispectral imagers at three to five metre resolution detect canopy loss reliably once a clearing exceeds roughly 0.5 hectares in cloud-free conditions. Vegetation indices drop sharply; bare soil and burn scars produce distinctive spectral signatures. The limit is cloud cover. Tropical forest regions frequently experience cloud fractions above 80 percent for weeks at a time, which means optical sensors alone will miss events. This is not a deficiency to be papered over; it is the central design constraint.

C-band synthetic aperture radar penetrates cloud and operates day and night. It does not see through dense canopy to individual trees, but it detects surface roughness changes that accompany clearing, and it maps access-road construction with high reliability because freshly graded earth has a markedly different backscatter signature than surrounding vegetation. River sediment plumes from alluvial gold mining are visible in both SAR and multispectral data: suspended sediment changes water-surface backscatter and colour in ways that persist for kilometres downstream of the extraction site.

Low-light night-time imaging adds a third detection layer. Dredges, generators and camp lighting produce radiance signatures detectable at roughly 100-metre resolution by sensors such as the VIIRS instrument on the Suomi NPP satellite, or by dedicated low-light payloads on smaller platforms. Night-time activity is particularly diagnostic for alluvial mining, where operations often continue through darkness to avoid detection. The limit here is that low-light sensors cannot distinguish a mining camp from a legitimate rural settlement without corroborating optical or SAR context. Fusion of all three data streams, not any single one, is what produces an enforceable alert.

The ambition ladder: from pilot alert system to sovereign constellation

A pathfinder programme uses existing commercial and public data feeds, processed through in-country infrastructure, to prove the alert pipeline before any sovereign satellite is built. The customer acquires processing hardware, exploitation software, trained analysts and a documented workflow. Latency depends on the revisit frequency of whichever commercial constellation provides the imagery, which the customer does not control. This is the honest limitation of the pathfinder tier: it demonstrates what is operationally possible and builds institutional capacity, but it does not deliver scheduling independence.

A dedicated constellation changes that. Two to four small satellites in sun-synchronous orbit, carrying both a multispectral imager and a C-band SAR payload, can achieve revisit intervals of 12 to 24 hours over a defined territory, depending on swath width and orbital spacing. Small-satellite missions of this class have publicly reported budgets in the range of tens to low hundreds of millions of dollars, depending on payload complexity and ground segment scope. India's Resourcesat series and ESA's Sentinel-1 programme provide publicly documented reference points for SAR and multispectral capability at this scale, though both are far larger than what a national enforcement constellation requires. A two-satellite constellation with a dedicated ground station and in-country processing is a credible sovereign capability; it is not a global mapping system, and it should not be specified as one.

The timeline from contract signature to first operational alert, for a pathfinder using commercial data, is typically six to eighteen months. A purpose-built constellation, including satellite integration, launch procurement and ground station commissioning, sits in the three-to-five-year range for programmes that proceed without significant regulatory delay. Spectrum coordination at the ITU is the most common source of schedule risk and should be initiated at programme inception, not after the satellite is built.

What the customer owns at handover

The point of a sovereign programme is that enforcement capability does not depend on a vendor's continued goodwill or a foreign government's export licence. At handover, the customer holds physical satellite infrastructure or ground station assets under national jurisdiction, source-access terms for all processing software, hardware audit rights exercised throughout the build, and a trained national team that can operate the system without external support.

What remains genuinely limited after handover is worth stating plainly. A two-satellite constellation cannot simultaneously monitor every corner of a large territory at 12-hour revisit; coverage is a function of swath width and the number of orbital planes. Cloud cover will still degrade optical revisit during wet seasons, and SAR processing requires sustained technical competence that takes years to build to full independence. The handover schedule is staged precisely because operating a SAR payload is not the same skill as operating an optical camera, and a national team that has only observed the process is not yet a national team that can sustain it.

From alert to enforcement: the data pipeline that makes detections actionable

A detection that sits in a database is not enforcement. The operational requirement is a workflow that moves from satellite pass to ranger dispatch in a timeframe short enough to matter. That means automated change-detection algorithms running on in-country servers, not data uploaded to a foreign cloud and returned days later. It means exploitation software with a map interface that a field coordinator can use without a data-science degree. And it means integration with the legal and administrative systems that authorise enforcement action, because a satellite alert is evidence, not a warrant.

In-country processing is both a sovereignty requirement and a latency requirement. When data must leave national jurisdiction for analysis, each border crossing adds hours and introduces dependency on foreign infrastructure. Processing within the country, on hardware the customer owns, eliminates both problems. The Satellize crop-estimation programme for the Kingdom of Tonga established the same principle at smaller scale: analytics running on sovereign infrastructure, with national staff trained to interpret and act on outputs, rather than a service delivered from abroad.

What this mission is built from

Multispectral imagers: Detects canopy loss, burn scars and bare-soil exposure in cloud-free conditions at three-to-five-metre resolution, providing the primary optical change-detection layer.
C-band SAR payloads: Provides all-weather, day-and-night detection of clearing, access-road construction and river-sediment plumes, compensating for the optical sensor's cloud limitation.
Low-light and night-time imagers: Identifies nocturnal mining and logging camp activity through artificial-light signatures, adding a third detection dimension that optical and SAR sensors cannot supply.
In-country data processing: Runs automated change-detection algorithms on sovereign hardware within national jurisdiction, reducing alert latency and eliminating dependency on foreign cloud infrastructure.
Exploitation and analysis software: Presents fused alerts from all sensor streams in a map interface accessible to enforcement coordinators, and maintains an audit trail of detections for legal proceedings.

What you end up owning

Ground station hardware and associated land or facility rights within national jurisdiction
In-country processing servers running licensed or open-source change-detection software under source-access terms
Exploitation and alert-management software with full documentation and modification rights
Satellite hardware (for constellation tier) or long-term data-access agreements (for pathfinder tier) with scheduling rights over the national territory
A trained national operations team capable of running daily processing cycles and interpreting outputs
Documented alert workflow integrated with enforcement agency dispatch and legal evidence procedures
Complete programme documentation including interface control documents, calibration records and operational runbooks

Handover is staged across the programme: ground station commissioning transfers first, followed by processing operations, then full satellite command authority as the national team completes qualification. Source-access terms and hardware audit rights are agreed before contract signature, not negotiated at handover. After full transfer, Satellize retains no operational role; optional long-term support arrangements, if required, are scoped and priced separately at the customer's election.
