BUILDING THE FUTURE OF GPS-DENIED NAVIGATION
Sentinel PNT Systems is being founded by Alexander Burns, who served as a GPS Operations Crew Chief at 2nd Navigation Warfare Squadron, managing critical GPS constellation operations.
Now pursuing Aerospace Engineering at CU Boulder (Class of 2030), Alex is combining operational GPS expertise with machine learning and signal processing to develop practical solutions for GPS-denied environments.
