Timing dependency review
Systems that use satellite navigation signals for timing, such as telecom networks and grid measurement, are identified with their holdover and backup options.
GCRI · Binesaziya girîng
Space pergalan provide positioning, timing, communications and observation that infrastructure depends on. In this field the concern is dependence on satellite timing and positioning, satellite backup communications, and imagery for asset monitoring and damage assessment.
Space pergalan and satellite services provide positioning, timing, communication and observation from orbit. Many terrestrial systems depend on them, making their disruption a cross-sector risk. In binesaziya girîng and cities and built environment, space systems analysis reveals dependencies of finance, power grids and transport on satellite timing and navigation. It supports planning for backups and space weather events. The canonical description is on STEM Commons.
Systems that use satellite navigation signals for timing, such as telecom networks and grid measurement, are identified with their holdover and backup options.
Satellite links available to operators and emergency services when terrestrial networks fail are documented with their capacity and activation steps.
Radar and optical imagery monitor ground movement near pipelines, dams and embankments, and map damage after events.

Pergal are tested on the ground before launch and monitored in orbit. Conjunction assessments and service performance are checked against independent tracking.
| Kontrol bikin | How it is done |
|---|---|
| Holdover verification | Claimed holdover times without satellite timing are tested |
| Alternative source review | Alternative timing sources are identified and their independence checked |
| Imagery accuracy | Satellite-based damage and movement estimates are validated in the field |
Debris growth, solar storms and interference are hard to forecast precisely. Ground segments and launch capacity are concentrated.

Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data.
