In-field ground-truth infrastructure that calibrates Copernicus from the soil. We turn ambiguous satellite indices into actionable agronomic diagnoses — for growers, cooperatives and climate-risk operators.
An NDVI drop can be drought, salinity, disease or a nutrient deficit. At 786 km those causes are spectrally degenerate: they look the same. That gap in field truth makes insurance, irrigation and fertilization more expensive in Latin America and the Caribbean.
Vegetation indices do not separate water, salt and nutrient stress. Different decisions need different causes; orbit alone does not deliver them.
Classic ground-truth campaigns depend on labs, technical staff and sampling windows. They sit out of reach for most growers in the region.
A relevant share of Latin American agriculture has no reliable internet. A solution that needs a permanent cloud fails where it is needed most.
A 10 m Sentinel-2 pixel averages real soil variability. Inside that pixel, pH and moisture can change in agronomically critical ways.
TerraProbe is a fusion platform: autonomous soil nodes, an edge gateway built for rural zones, and a calibration engine that crosses in-situ truth with Copernicus. The product is not another dashboard: it is measurement infrastructure that makes satellite observation interpretable.
Each node observes soil state — moisture, reaction (pH) and conductivity, among others — to tell apart causes that a vegetation index confuses.
We cross reflectance, radar and climate with local readings. The result is a soil-health index, not a decorative map.
The network runs without a permanent link. It stores at the edge and syncs when connectivity returns. Built for farms, not data centers.
The model is a low-cost mesh per hectare, not a fifty-thousand-dollar weather station. Density is what makes spatial calibration useful.
The system is described by business functions, not an assembly recipe. Field hardware is TerraProbe intellectual property; this page shows how it creates value, not how it is built.
Copernicus · climate · spatial interpolation
Cross-validation between vegetation indices and soil readings per pixel.
Geostatistical interpolation of the mesh to cover the plot, not only the sensor point.
Soil health on a 0–100 scale, ready for irrigation, nutrition and risk.
Deferred sync when a link is available
Rural operation · local store · batch publish
Long-range link between nodes and gateway, independent of cellular coverage.
Local buffer of readings during long network outages.
Secure send when connectivity returns, without losing the time series.
Low-power field telemetry
Autonomous · weather-sealed · closed design
Joint reading of hydric, chemical and electrical state in the profile of interest.
Signal conditioning and reduction at the edge; the internal circuit is not published.
Solar capture and deep-sleep cycle for continuous operation at tropical latitudes.
We publish functions, service performance and deployment economics. Component references, probe topology and firmware are not part of this commercial sheet.
Moisture, pH and conductivity in one field station, to separate drought, salinity and nutrition.
Several nodes per farm, with a long-range link from plot to gateway, without depending on a cell tower.
Solar operation at LAC latitudes, with low-power cycles designed for permanence, not a one-day demo.
Local temperature and atmospheric conditions to read the soil alongside Copernicus climate reanalysis.
Deployment target on the order of USD 200 per field node, so spatial calibration is viable — not a lab instrument.
Electronics, firmware and probe geometry ship as an assembled product or under a confidentiality agreement.
Material, schematic and supplier detail is not published. Partners, integrators and technical evaluators receive restricted documentation after a non-disclosure agreement.
Each node anchors open Copernicus products with near-real-time field measurements. The index stops being a symptom and becomes a diagnosis.
Ten metres in optical and near infrared. TerraProbe anchors NDVI, EVI and NDWI with pH, moisture and conductivity to detect real stress, not just greenness.
NDVI · EVI · NDWI
Continuous observation through cloud or rain. Backscatter informs moisture and biomass; it complements Sentinel-2 in the tropical wet season.
VV / VH · Cloud-free · Revisit
Temperature, precipitation and evapotranspiration to place each node reading in the regional water balance, not only in the planting hole.
Sentinel-2 + Sentinel-1 + ERA5 + TerraProbe. Spatial calibration for irrigation, nutrition and early warning — a figure a farm manager can use.
Copernicus sources in use: Sentinel-2 SR · Sentinel-1 SAR · ERA5 climate
TerraProbe is offered as measurement infrastructure plus an intelligence platform, not a hobbyist kit. The value is in the agronomic decision and in risk reduction, not in a parts inventory.
Know whether stress is hydric, saline or nutritional before spending water or fertilizer. Node density per plot, not a single station.
A field-truth network for food-security, extension and degradation-monitoring programmes, anchored to Copernicus.
In-situ series that separate drought from other damage, useful for underwriting, claims and climate scoring.
Mesh deployment, access to fused indices and technical support. Internal material detail is shared only under contract.
More affordable than a traditional ground-truth calibration campaign
Permanent cloud dependence. It runs without a link and syncs when the network returns
Separates drought, salinity and other stress the satellite sees as one symptom
TerraProbe emerged at the CopernicusLAC Hackathon 2026 in Panama, on the food-security track. The prototype showed that field sensors and open Copernicus data can solve a real farm problem. The next step is product, design confidentiality and scale.
Cooperatives, satellite operators, insurers and agrifood innovation teams: we can evaluate a controlled deployment and share results, not schematics.
