Método dos mínimos quadrados aplicado a um problema de geoposicionamento

Abstract

The main goal of this work is to present the least squares method to solve overdetermined linear systems, that is, systems of the form Ax = b , where A m×n , with m > n . In this sense, we showed that the resolution of these systems is related to the orthogonal projection problem of b on the subspace generated by the columns of A. This type of system is used to model a problem of geo-positioning, whose objective is to determine the position of a receiver that receives the signal from several satellites.
