ORBISPECT MEDIA BRIEF · FOR CITATION

SATELLITE GRAVIMETRY × ORBISPECT ENGINE · AS OF Q2 2026

Europe is drying out in silence. We weigh it — from orbit.

A pair of satellites weighs the water beneath our feet by measuring changes in Earth's gravitational pull — among the most sensitive water instruments humanity has put in orbit. Our engine brings this planetary signal down to the powiat level. The red on this map is not a dry month — it is a structural trend that no single rainy season will fix.

INSTRUMENT

2 satellitesgravimetry measures the distance between the twin satellites to a fraction of a human hair's width — that is how a continent's water is "weighed"

Gravity betrays mass

Where there is more water underground, Earth pulls harder. A pair of satellites senses that difference by measuring their mutual distance to within micrometres.

Mass turns into water

After subtracting the signals of ice, atmosphere and crustal tides, one thing remains: total terrestrial water storage (TWS) — soil, snow, rivers and, most importantly, aquifers.

The region becomes a powiat

A raw gravimetry pixel spans hundreds of kilometres. Our engine descends to the powiat level, learning local hydrology from models, precipitation and soil moisture — with uncertainty preserved.

Trend, not weather

From 23 years of data we extract the slope: how much water disappears year over year once the season is removed. This separates a passing drought from a sustained draining of reserves.

01B · THE LEVEL WE MEASURE AT — AND THE LEVEL EVERYONE ELSE DOES

RAW GRAVIMETRY SIGNAL — WHAT IS VISIBLE FROM ORBIT

whole region

a single pixel covers an area the size of half of Poland. All of Greater Poland is literally a handful of measurement points — useless for a decision about a single powiat or farm

AFTER THE ORBISPECT ENGINE — WHAT THE CLIENT RECEIVES

powiat

the same mass signal, brought down to the powiat (LAU) level — ~380 powiats in Poland alone. Each powiat gets its own trend and its own uncertainty, ready for pricing and scoring

This is exactly our added value. Satellite gravimetry is among the most sensitive water instruments in the world, but at the resolution of whole regions. No one will make a credit decision on a pixel the size of a province. Our engine — trained on local hydrology, precipitation and soil moisture — descends from the level of a whole region to the powiat level, preserving mass fidelity and openly reporting where it is confident and where it is not. That is the difference between "Europe is drying out" and "this particular powiat is losing water at rate X, with statistical significance Y".

02 · WHAT THE DATA ACTUALLY SHOWS

A map that does not lie about the season

Every gauge and every satellite image shows the state on a given day. Gravimetry shows something else: a water-mass balance summed over years. That is why a wet week does not turn the colour red, but a dry decade does.

In parts of Central and Southern Europe the slope of the trend is negative and statistically significant: aquifers give back more than they receive. This is not a model hypothesis — it is measured mass, independent of rainfall, clouds and vegetation.

The most dangerous areas are the ones where the surface looks normal. The field is green, the river flows, and yet gravity says the water is disappearing — because the deep reserves are being drained, invisible from the ground or from an optical image. This is precisely the signal we catch by crossing the surface balance with gravimetry.

"The red on this map is not a dry month — it is a structural trend that no single rainy season will fix."

SIGNAL MEASURED, NOT MODELLED · INDEPENDENT OF WEATHER

Hidden depletion: surface balance vs gravity

HIDDEN DEPLETION · THE SURFACE LOOKS NORMAL, GRAVITY SAYS OTHERWISE · ILLUSTRATIVE RENDERSURFACE BALANCE × GRAVIMETRY

The layer above is the core of our product: for each powiat we compute the difference between what the surface says (precipitation minus evaporation minus soil moisture) and what gravity says. When both agree that it is dry — that is a known drought. When the surface is calm and gravity falls — that is hidden drainage, a leading signal that appears in no external report.

03 · WHAT OTHER METHODS WILL NOT SHOW

METHOD	WHAT IT MEASURES	DEEP WATER?	MULTI-YEAR TREND?
Gauge / piezometer	level at a single point	yes, but locally	only where it stands
Weather model	precipitation and temperature	no	forecast, not reserve
Optical image	plant condition at the surface	no	season, not decade
Gravimetry + Orbispect engine	total water mass, including deep	yes, across the whole area	23 years, continuous

None of the top three methods sees what the fourth does. That is why we do not replace gauges — we combine them with gravimetry, so that the local truth of a borehole calibrates the global mass measurement. The result: one coherent, explainable water-health indicator for each powiat.

04 · WHO BUYS THIS AND WHY

INSURER

Pricing drought risk

A structural trend in an agricultural portfolio means rising claims. The per-powiat indicator feeds directly into pricing and payout triggers — before the season confirms it.

MORTGAGE / AGRI BANK

Water solvency of collateral

Land above a drying aquifer loses productive value. This is a credit risk absent from every scoring model today — and we deliver it as a number.

WATER UTILITY

Intake horizon

How many years does a given intake have left at the current rate of drainage? The gravimetric trend gives the reserve's runway, long before the well begins to fall.

ANALYST / REGULATOR

Proof independent of weather

The argument over whether "it is just a dry year" ends at measured mass. Gravimetry is evidence that cannot be undercut by one season's rainfall.

05 · HOW WE KNOW THIS

METHOD AND CREDIBILITY

Satellite gravimetry — a pair of twin satellites weighing a continent's water mass, across multiple independent solutions combined into an ensemble
23-year series — an unbroken record from 2002 to today, stitched into one continuous record
Surface balance — precipitation, evapotranspiration and soil moisture from independent constellations
Validation — cross-checked against independent piezometer networks and national borehole data
Downscaling — physically constrained machine learning with a consistency guarantee and explicit uncertainty
Updates — with every new data release, no guessing between releases

Full methodology and data sources are made available under NDA, in a secure data room.

Three sentences for the newsroom

1. This is not a drought — it is a trend. A drought passes with the rain; gravimetry shows a multi-year, systematic loss of water mass, measured independently of the weather.

2. The most dangerous part is invisible. Where the surface looks normal and gravity falls, the deep reserves are being drained — a risk no gauge will show.

3. From orbit to the decision-maker's desk. We bring the planetary signal down to the powiat and turn it into one explainable indicator, updated monthly and validated against boreholes.
