摘要：Spinning vehicles present significant challenges for Global Navigation Satellite System (GNSS)-based navigation due to signal distortions induced by antenna rotation, including amplitude fluctuations, Doppler frequency shifts and phase modulation. These effects can severely degrade signal tracking performance and positioning accuracy. To address these issues, we developed and implemented an Inertial Navigation System (INS)-aided extended Kalman filter (EKF) tracking loop that explicitly models and compensates for spin-induced signal dynamics. The integrated navigation filter also corrects critical lever arm and signal time delay errors, identified as key sources of tracking inaccuracy under spin conditions. Experimental validation using a single-axis rotation table and GNSS signal simulator shows that the proposed method improves positioning accuracy by up to 83.0 % in low-speed spin and 75.3 % under non-uniform rotational acceleration reaching 2000 degrees/s2. It also enhances tracking stability in circular motion scenarios. These results confirm the method's effectiveness and adaptability in both steady and dynamic spinning conditions, enabling robust and precise GNSS navigation for a critical class of spinning vehicles.
