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.

95 m & 88 m
Two towers trap DR-03 (50 m) in a canyon with zero optical line of sight.

Relay DR-01 & DR-02 orbit above every roof with clear laser to HQ.
2-Hop
DR-03 penetrates the 88 m tower via 1.9 GHz DECT NR+ up to DR-01.

1 · Outer Yellow Circle · GPS Spoofing

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.

Autonomous recovery · 10/10 Reachability
When every radio fails, climb.
