The Global Centre for Risk and Innovation (GCRI)
SIG covers signal integrity: radio spectrum, interference, propagation, and positioning, navigation and timing signals that power grids, telecoms and finance share.

Signals Integrity Grid is the Nexus Foundry system for authorized spectrum monitoring and observation of signal and positioning integrity. It serves 4 platforms, among them Critical Infrastructure as well as Cybersecurity and Digital Resilience, and its stated limit is that there is no unauthorized collection. Access is through an authorized project with an accountable owner, data terms and a review plan.
Urban demand centres and the hubs that anchor digital and data infrastructure, shown for Poland as an example geography for this subject.
Satellite navigation timing synchronises grids, telecoms and payment systems; jamming, spoofing or space weather can disrupt them all at once. Spectrum interference can degrade warnings and observation. Few operators map this dependency.

Access requires an authorized project with an accountable owner, data terms and a review plan. Enquiries go to contact@therisk.global.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| GNSS | Global navigation satellite systems, such as GPS and Galileo, that provide positioning and timing. |
| Jamming | Deliberate transmission of signals that block reception of satellite signals. |
| Spoofing | Placing orders with the intent to cancel them before execution, to mislead others about supply or demand. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
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.
