The problem · How drone fleets fly today
Today's fleets rely on 2.4 GHz, 4G/5G & GPS. In a crisis, all three fail.
01 · PUBLIC SPECTRUM
2.4 GHz & 4G/5G jam
Commercial drones use 2.4 / 5.8 GHz ISM radio (OcuSync, MAVLink) or public LTE/5G. A broadband jammer or grid blackout wipes both out.
02 · STAR TOPOLOGY
No relay, no QoS
Each drone talks straight to ground. When a street canyon shadows the link, neighbors can't relay—and HD video starves command-and-control.
03 · BLIND NAVIGATION
GPS spoofed, alarms late
Autopilots trust unauthenticated GNSS L1 fixes, while rolling-window threshold alarms stay blind to slow-ramping attacks for ~9 s.
Our answer · Move off jammed RF
Optical lasers beat the jammer. Now the city is the obstacle.

INS cross-check rejects fake GPS. Compares satellite fix against internal IMU/INS sensor; stays on course.
2 · Middle Red Circle (>150 m) · Jamming
DECT NR+ backup + Video Shed (0 %). Video eats 99 % of bandwidth; shedding it keeps 12 kbps C2 steering at 100 %.
3 · Inner Purple Circle (<150 m) · Double-Fail
Laser blocked + Radio crushed (DR-03). Triggers autonomous INS/VIO Pop-Up climb above the U-Tower roof.
