Sub-Meter Accurate Navigation And Cycle Slip Detection With Long-Term Evolution (LTE) Carrier Phase Measurements
Tech ID: 34254 / UC Case 2020-606-0
Brief Description
A novel navigation framework leveraging LTE cellular signals enables sub-meter level accurate UAV positioning in GNSS-challenged environments.
Full Description
This technology utilizes long-term evolution (LTE) carrier phase measurements to achieve sub-meter-level accurate unmanned aerial device (UAV) navigation. It overcomes limitations of Global Navigation Satellite System (GNSS) in urban canyons and interference-prone areas. Experimental results demonstrate an 81 cm two-dimensional positioning accuracy over a 605 m UAV trajectory, offering a reliable alternative or complement to GNSS for UAV navigation.
Suggested uses
- Unmanned aerial vehicle navigation for package delivery and traffic monitoring in urban areas.
- Military and defense UAV operations requiring secure and reliable positioning.
- Agriculture, construction, mining, mapping, and surveying using UAVs in GNSS-challenged terrains.
- Integration with automotive and aerospace navigation systems for enhanced location accuracy.
- First responders and emergency services deploying UAVs in complex environments.
Advantages
- Provides sub-meter level positioning accuracy in environments where GNSS signals are weak or unreliable.
- Robust against jamming and spoofing attacks common in GNSS systems due to LTE signal diversity and power.
- Utilizes existing cellular infrastructure without requiring additional hardware deployment.
- Innovative cycle slip detection enhances measurement reliability and navigation accuracy.
- Fuses multiple LTE signal measurements to improve UAV position and velocity estimates in real time.
