OPPORTUNITY

PROBLEM

– GPS signals are weak; can be broken, jammed,

r spoofed
SOLUTION

– Use existing commercial broadcast signals to augment GPS

PRODUCT

– Low power, light-weight radio + signal analysis

SLIDE 3

MARKET

Government

– Military, first responders, aerial surveillance

Commercial

– Amazon, Google, others investigating use of UAVs

Agricultural/Industrial

– Crop maintenance/inspection

VC investment, global UAV market

show continuous growth

North America, Europe expected

to hold 67% market share

TECHNOLOGY

Competing devices to combat signal loss:

– Inertial systems

Susceptible to accumulated error
Greater accuracy = greater cost

– Ground-based reference stations

Requires infrastructure (costly)
KU Invention:

– Calculates position based on signals received in miniature RF receivers – Makes use of transmitter database

Maintained by FCC in US

FEATURES AND BENEFITS FEATURES

Low power requirements
Low weight/size

– High performance RF circuitry

Accuracy sufficient to supplement GPS

BENEFITS

Protection from lost signals, jamming, spoofing

– Prevents flyaway, hijacking

Provides a check for GPS accuracy
Designed for assembly from commercially available

components

VALUE PROPOSITION

Military UAVs present safety, national security risk if GPS fails
Civil UAV testing requires FAA approval of control systems

– Backup system for GPS reduces safety risk

System is adaptable to other types of vehicles (e.g., ground or water-

based) or other types of signals (e.g., WiFi, acoustic, or optical)

NEXT STEPS

Additional Product Development/Testing

– Computer simulation has been partially verified by ground-based testing using FM broadcast signals – In-flight testing will require trained personnel to:

assemble and install hardware on aircraft
collect and process the data
Build Industry Involvement

– KUCTC marketing campaign underway to identify companies capable of further development
