Adaptive Kalman filter boosts BDS-3 navigation accuracy in challenging environments
A new PPP strategy integrates a covariance-adaptive Kalman filter to compensate for sudden orbit and clock jumps, improving horizontal, vertical, and 3D accuracy. Tests show significant gains in accuracy, demonstrating the algorithm's ability to deliver robust sub-meter real-time positioning even in network-limited environments.
