Dense urban canyons do not just complicate guidance; they break many current systems. When high-rise buildings obstruct line-of-sight satellite signals, GPS drift occurs. Multipath interference—where radio signals bounce off concrete and steel—creates ghost images that confuse sensors. These aren't minor glitches. They are fundamental physical barriers that render traditional, signal-dependent tools unreliable in tight quarters.
We aren't seeing a need for a complete rebuild from scratch, but rather a massive shift in priority. Relying solely on external data like GPS is a losing strategy in a city. Instead, engineers are moving toward autonomous, onboard processing. Modern munitions must rely more on computer vision, LiDAR, and inertial measurement units (IMUs) that function without any external signal. If a missile can't
