Orbit Determination Error Analysis for the KOMPSAT [PDF]
Journal of Astronomy and Space Sciences, 1998 Orbit error analysis was performed for the GPS navigation solutions and ground station tracking data of the KOMPSAT (Korea Multi-Purpose SATellite), which will be launched in 1999 for cartography of Korean peninsula as main mission. A least square method

四川大学学报. 自然科学版, 2021 We investigate the crossing periodic orbits of a piecewise linear Lienard-like system with symmetric admissible foci. By reducing the system to a normal form with less parameters and constructing the Poincare maps for the left and right subsystems, we ...

Unstable periodic orbits and attractor of the barotropic ocean model [PDF]
Nonlinear Processes in Geophysics, 1998 A numerical method for detection of unstable periodic orbits on attractors of nonlinear models is proposed. The method requires similar techniques to data assimilation. This fact facilitates its implementation for geophysical models. ...

A Digit-Based Discrete Dynamical System Generated by a Figure-Changing Transformation
Applied Mathematics on Science and EngineeringDigit-based iterative processes often give rise to rich dynamical behavior despite being defined by simple arithmetic rules. In this paper, we investigate a figure-changing transformation acting on four-digit numbers, where each iteration is obtained by ...

Method of Weak Signals Detection Based on Chaos Suppression in the Nonresonant Parametric Drive
Journal of Measurement Science and Instrumentation, 2011 The evolution of chaotic state of Lorenz system on the familiar parameter space orbit is analyzed.Based on the principle of chaos suppression with nonresonant parametric drive,the model of detecting weak periodic signals in strong noise is built ...

Dynamical analysis of an integrated pest management predator–prey model with weak Allee effect
Journal of Biological Dynamics, 2019 In this paper, a pest management predator–prey model with weak Allee effect on predator and state feedback impulsive control on prey is introduced and analysed, where the yield of predator released and intensity of pesticide sprayed are assumed to be ...
