GNSS Navigation Knowledge Patch

Claude's baseline covers basic GPS/GNSS concepts, WGS84, and satellite constellations (GPS/GLONASS/Galileo/BeiDou). This skill provides the practical implementation details needed to write GNSS positioning code: observation equations, correction protocols, receiver configuration, and platform APIs.
