Item A direct approach to deriving filtering equations for diffusion processes(2000-04) Krylov, N.V.; Zatezalo, AleksandarItem Filtering of finite-state time-nonhomogeneous Markov processes, a direct approach(2000-04) Krylov, N.V.; Zatezalo, AleksandarItem Interferometric GPS ambiguity resolution(2001-07) Poling, T. Craig; Zatezalo, AleksandarThe Maximum a Posteriori Ambiguity Search (MAPAS) method for GPS ambiguity resolution is generalized to accommodate: (1) satellite switches caused by satellites rising or falling below the horizon or obstructing terrain, and (2) cycle slips due to temporary loss of lock on satellite signals. It is shown that MAPAS and generalized MAPAS are equivalent to Bayesian estimation. The generalized MAPAS method is successfully applied to real GPS satellite data with cycle slips and satellite switches due to satellite obstruction.Item A nonlinear filter for real-time joint tracking and recognition(1998-04) Kastella, Keith; Zatezalo, Aleksandar
