What exactly does a satellite detect that ground-based sensors miss?

Ground sensors measure temperature and flow at fixed points — valves, substations, meters. They are blind to anomalies between those points. A TIR satellite produces a continuous thermal map of the entire network footprint in a single pass, revealing diffuse leaks, under-insulated sections and illegal heat taps that no ground sensor would flag because they sit between measurement nodes.

How often can a purpose-built constellation image a given city?

A 12-satellite LEO constellation in sun-synchronous orbits spaced for thermal coverage can achieve sub-6-hour revisit over a target city. A sovereign operator can tune inclination and phasing to prioritise its own urban centres, something no commercial service-as-a-service contract can guarantee.

Is the 0.1 K thermal sensitivity enough to detect real pipe leaks?

Yes for most district heating leaks. A medium-pressure hot-water pipe losing even a modest flow elevates the overlying soil surface by 1–4 K relative to background, well above the 0.1 K noise-equivalent delta-temperature of sensors like Landsat 9 TIRS-2. The challenge is not sensitivity but spatial resolution and cloud cover, not raw temperature precision.

Can this replace physical inspection teams?

No — and it should not try to. Satellite TIR is a prioritisation and screening tool. It narrows a network covering hundreds of kilometres down to a handful of suspect segments that warrant ground crew investigation. That redirection alone can cut inspection costs by 40–60% according to ESA Phi-Lab pilot studies, while improving detection rates compared to fixed inspection schedules.

What resolution is actually needed for meaningful pipe-level analysis?

For distribution pipes with 200–600 mm diameters the thermal plume at the surface is typically 1–3 m wide. A satellite with 3–5 m GSD can reliably detect these plumes, though pixel attribution to a specific pipe is aided by sub-metre GIS overlays. Transmission mains produce wider signatures detectable at 10–30 m resolution, which Copernicus Sentinel-3 SLSTR already provides.

Why build a sovereign constellation rather than simply buying Copernicus or Landsat data?

Copernicus LSTM (launch planned late 2020s) and Landsat 9 offer 16-day revisit at best for any single path — far too slow for operational network management. Sovereign operators can task their own satellites on demand, maintain data custody, avoid export-control complications, and tune the imaging schedule to pre-dawn passes that minimise solar contamination over their specific cities.

How does satellite data integrate with a district heating SCADA system?

The standard pathway is OGC Sensor Observation Service (OGC 12-006) APIs that ingest processed thermal anomaly vectors as geospatial events, which the SCADA or GIS platform then correlates with real-time flow and pressure telemetry. Most modern DH SCADA platforms support OGC-compliant data ingestion, so integration is a configuration task rather than a bespoke development effort.

What is the business case — does the saved heat loss justify the satellite programme cost?

Euroheat & Power estimates undetected leaks cost Nordic networks alone roughly €180M per year. A sovereign 12-satellite TIR constellation capable of monitoring all national district heating infrastructure can be built and operated for under €150M over a 10-year lifecycle at current microsatellite costs. Even modest improvement in leak detection rates — 15–20% of currently undetected losses — returns the investment within the first operational years.
