Hardware-in-the-loop verification of GNSS-based orbit determination, time synchronization, and oscillator disciplining for LEO-PNT
To demonstrate the feasibility of autonomous real-time ODTS and assess the achievable performance, a realistic hardware-in-the-loop simulation for a LEO environment is employed and the carrier-phase-based real-time ODTS enables a significantly better clock synchronization than traditional GNSS-disciplined oscillators.
