Investigation 001 · navigation
Remove a source. Watch an uncertainty interval meet a boundary. Inspect what supports the result—and what the experiment cannot establish.
Synthetic evidence / interface research
Explore an illustrative likelihood field. This study is synthetic and does not provide a calibrated position estimate or navigation integrity.
Open the position likelihood study ↗Systems research / analytical model
Inspect a bounded cost model with explicit isolation and overhead assumptions. It does not establish latency, safety or whole-system performance.
Explore the state reuse model ↗Knowledge carried forward
Pacific wayfinding brings observations of stars, the sun and ocean swells together to navigate at sea. Nainoa Thompson learned from Mau Piailug, a master navigator from Satawal, carrying knowledge between people and generations.
Polynesian Voyaging Society ↗Harrison’s H4 longitude watch, completed in 1759, is one example of navigation advancing through careful instrument making. Its history places measurement and timekeeping alongside the practice of observation.
Royal Museums Greenwich ↗These histories inform the questions we ask. The linked accounts provide cultural and historical context; the source-loss investigation has its own inspectable model and assumptions.
