Ku-Band Array Antenna for Using LEO Satellite Signals in PNT

This project explores the use of signals from OneWeb and Starlink LEO satellite networks as an alternative to traditional Global Positioning System/Global Navigation Satellite System (GPS/GNSS) for positioning and navigation, aiming to overcome limitations like satellite visibility and signal strength. The CARMEN+ team at The Ohio State University, led by Dr. Zak Kassas, achieved 7.7-meter position accuracy using Starlink signals with commercial off-the-shelf horn antennas. The research seeks to design, fabricate, and test a low-profile Ku-band antenna array with 4-6 elements, focusing on optimizing beam-forming performance to ensure uninterrupted and accurate positioning. The project will use advanced digital beam-forming techniques to enhance satellite tracking and signal strength, ultimately aiming to improve positioning accuracy and robustness against interferences. Expected outcomes include a prototype antenna design, validated performance measurements, and potential new intellectual property.
