DOI: 10.1117/1.oe.56.2.026112
Abstract: Abstract. Static position errors are usually ineluctable during the assembly of a satellite optical communication terminal, which will lead to pointing errors and make it difficult to establish an optical communication link. The model resulting… read more here.

DOI: 10.1175/mwr-d-22-0140.1
Abstract: A multiscale alignment (MSA) ensemble filtering method was introduced by Ying to reduce nonlinear position errors effectively during data assimilation. The MSA method extends the traditional ensemble Kalman filter (EnKF) to update states from large… read more here.
