Why GPS fails indoors—and the warehouse fix

GNSS signals are attenuated by roofs and corrupted by multipath. Autonomous indoor flight needs infrastructure-backed navigation.

UWB uses time-of-flight between a drone tag and fixed anchors; with anchors above and beside aisles we obtain a stable 3D fix.

Rollout steps: RF survey, coverage planning, anchor install, calibration, alignment to the warehouse coordinate frame.
