| English abstract | The main goal of this work is to show an investigation on the improvement of the newly developed Doppler based Brazilian geographic location system using the data reception network software. The Doppler data measurement set of a single satellite pass and a single DCP (Data Collecting Platform), considering a network of ground reception stations, is named as the data reception network. Thus, increasing the terrestrial reception stations around the Brazilian territory, will allow an increment in the coverage and amount of data collected. Consequently the accuracy of the computed locations would also increase as well as the reliability figures. The results and analyses were obtained under two conditions: the first one used both ideal simulated and real conditions to compare results from the same satellite passes, DCP and two known ground reception stations, the second one used ideal simulated conditions from measurements of one DCP transmitter, three ground stations and two satellites. Results using such database were quite satisfactory |

Um conjunto de medidas de desvio Doppler de uma unica passagem do satelite, considerando uma Plataforma de Coleta de Dados (PCD) e uma rede de estacoes de recepcao terrestres, e denominado uma rede de recepcao de dados. Assim, a rede brasileira de coleta de dados com o uso de m´ultiplas estacoes de recepcao permitira o incremento na quantidade de dados coletados com consequente melhora na precisao e na confiabilidade das localizac¸oes fornecidas |
