RGSRResonant Geophysical Systems Research

A governed instrument for coupled physical systems

CORE models how ground, groundwater, air, sound and structures interact. It freezes what the models predict, then tests those predictions against calibrated instruments. Every result is sealed, replayable and reported as it is: pass, fail or inconclusive.

Three parts, one discipline

Deterministic engines

Room and open-air acoustics, 2-D and 3-D wave fields, layered ground, groundwater tides, the local magnetic field and sky geometry. The same inputs always give the same sealed outputs.

Calibrated instruments

Microphones, seismometers, loggers and geometry tools enter through a calibration lab. Raw recordings are kept byte for byte; nothing is filtered or resampled.

Correlation-only fusion

Sealed outputs from different domains are compared side by side. Fusion reports how signals align; it never asserts cause, intent or meaning.

How a result is made

  1. Freeze the prediction, with its extraction method, comparison rule and validity envelope.
  2. Calibrate the instruments against references. Calibrations are sealed and expire.
  3. Measure and seal on declared hardware, bound to the frozen prediction.
  4. Report the verdict, recomputed independently. Failures are kept on the record.
