This is the packet GeoTag Pro writes to the camera's location characteristic for a fix at the Sydney Opera House. 95 bytes, big-endian, no checksum. Watch it decode, then pick a field or a byte to read it.

Public packet only. The camera also needs a validation handshake and timing beyond the public spec, and those are not published here. The format builds on the community's ILCE7M3ExternalGps protocol notes.

Bits of the selected field, most significant first
