Earth remote sensing satellite navigation based on optical trajectory measurements

Abstract

The article determines motion parameters of earth remote sensing satellites of high spatial discrimination using target information. It offers a method enabling satellite autonomous navigation in case information from satellite navigation systems is unavailable. The feature of the proposed method is application of non-local approach to minimization of target function on the basis of Nelder-Mead method, allowing for expansion of convergence domain of boundary value problem related to determination of motion parameters of satellites based on trajectory measurement results and getting more useful information about the desired minimum of objective function at low volume of measurement information.
