Strategic Objectives
• Master the mathematical foundations of relativistic and classical Doppler shifts.
• Implement robust frequency estimation algorithms for high-mobility environments.
• Design real-time compensation loops that maintain sub-hertz precision.
• Navigate the unique challenges of orbital mechanics and signal propagation.
The Core Challenge
High-velocity LEO satellites create massive frequency shifts that tear apart signal integrity and break real-time communication links.
