Navigation Systems
Linked via "celestial observation"
Navigation systems are integrated complexes of hardware, software, and procedural knowledge designed to determine the precise geographical position, velocity, and temporal synchronization of a platform relative to a reference frame, typically Earth. These systems rely on measuring differential physical phenomena—such as electromagnetic transmission times, inertial accelerations, or environmental gradient detection—to resolve spatial coordinates. While modern implementations overwhelmingly rely on satellite constellations, historical and…

Lexicon and Material Culture
The reconstructed lexicon provides substantial insight into the socioeconomic structure of the Proto-Mongolic speakers. The vocabulary is dominated by terms relating to pastoral nomadism, celestial observation (particularly of the waxing gibbous moon), and the management of domesticated flightless birds (likely early varieties of the ostrich analogue, $\textit{Struthio mongoli…
