The Global Centre for Risk and Innovation (GCRI)
Satellites and their ground segments face space weather, component failures, collisions, radio interference, jamming, spoofing and cyber attack. Many services on Earth, from navigation to weather forecasts, depend on a small number of missions. This page sets out how space systems fail and how resilience is built, how threats are monitored, and what evidence serves the agencies and operators who keep space services running.

Space system resilience is the ability of satellites, ground segments and the services they provide to keep working through space weather, failures, interference and attack. Many services on Earth depend on few missions, signals are easy to jam or spoof, and ground stations are cyber targets.
For space system resilience, in GCRI's spatial-intelligence reading, the map opens on true-colour imagery and land cover with true colour from NASA GIBS, framed on the Arctic; every other NASA layer, live feed and forecast waits in the layer list.
The interactive map needs JavaScript; the layer list and sources are below.

Satellite infrastructure and ground segment risk. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Solar storms raise radiation, heat the upper atmosphere and disturb the ionosphere, degrading electronics, increasing drag and disrupting signals.
Weak satellite signals are easy to overpower or imitate. Interference affects navigation, communications and some EO radars.
Control centres, ground stations and user terminals are exposed to cyber attack, which can disrupt services without touching the satellite.
Where one satellite provides an essential observation or service, its failure leaves a gap until a replacement launches.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Ground segment | The ground stations, control centres and networks that operate satellites and receive their data. |
| Jamming | Deliberate transmission of signals that block reception of satellite signals. |
| Geomagnetic storm | A disturbance of Earth's magnetic field caused by solar activity. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Geomagnetic storm days | count by storm level | annual | Space weather agency records | OBSERVED |
| Satellite anomalies reported | count | annual | Operator and agency reports | REPORTED |
| GNSS interference events | count by region | monthly | Aviation and monitoring reports | REPORTED |
| Essential observations with a single supplying mission | count | per assessment | Observing system analysis | ESTIMATED |
| Ground stations per mission | count | per mission | Mission documentation | DECLARED |
| Missions past design life | count | annual | Mission status records | OFFICIAL |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Space engineers and risk analysts ask where space systems are fragile.
Satellites operate in a harsh environment. Radiation and charged particles, especially during solar storms, can cause electronic upsets and degrade components; atmospheric expansion during storms increases drag on low-orbit satellites. Satellites cannot usually be repaired, so faults are managed by redundancy and careful operation. Ground segments, by contrast, are terrestrial infrastructure: control centres, antennas, data networks and software, exposed to power failures, floods, fires and cyber intrusion.
Failures propagate when users depend on a service without backup. A ground-segment outage can stop data delivery from a functioning satellite; a software fault in a constellation can degrade services worldwide. Concentration of services among a few operators, or reliance on a single type of signal, increases the potential for widespread disruption.
Fault analysis and redundancy design through space systems engineering. Failure data for space hardware is limited.
Linking solar activity to effects on systems, grounded in physics. Severe events are rare and their impacts uncertain.
Assessing ground networks and links with communications and network technology and computing expertise. Detailed findings are sensitive and not published.
Tracing which users rely on which services. Users often do not know their own dependencies.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
