1. UAV Navigation Using Signals of Opportunity

2. Opportunity
PROBLEM
GPS signals are weak; can be broken, jammed, or spoofed
SOLUTION
Use existing commercial broadcast signals to augment GPS
PRODUCT
Low power, light-weight radio + signal analysis

3. Military, first responders, aerial surveillance Commercial
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

4. 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

5. 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

6. Value Proposition
Prevents loss of aircraft and collateral damage associated with:
Spoofing
Jamming
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)

7. 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
