Abstract
Smoothing as a way to improve the carrier phase estimation is proposed and analyzed, The performance of first- and second-order Kalman optimum smoothers are investigated. This performance is evaluated in terms of steady-state covariance error computation, dynamic tracking, and noise response. It is shown that with practical amounts of memory, a second-order smoother can have a position error due to an acceleration or jerk step input less than any prescribed maximum, As an example of importance to the NASA Deep Space Network, a second-order smoother can be used to track the Voyager space' craft at Uranus and Neptune encounters with significantly better performance than a second-order phase-locked loop.
