This paper describes methods for velocity determination in high dynamic flight using a stand-alone single-frequency GPS receiver. The work is of interest, and the proposed scheme is valuable for practice. Simulations are developed with a GPS signal simulator and a GPS receiver,where the aircraft velocity is up to 7000 m/s, and the acceleration is up to 7 g (9.8m/s2). The performance of the receiver...
This paper investigates biases of a parametric estimator of Doppler shift in mobile communications, and the result indicates that the conventional iterative autocorrelation function (ACF) estimator yields a significant estimation error at high mobile speeds. Therefore, a simple linear fitting is proposed to refine the Doppler shift estimation, in which only one fitting expression is required for different...
