Abstract:	With the growing demand for Location Based Servers(LBS), especially the demand for urban and indoor positioning, the development of high performance receiver--High Sensitivity receiver has become a hot in the navigation field. Because of the compatible characteristic of Galileo Open Servers(OS) signal and GPS signal, the development of high sensitivity dual mode navigation receiver has become the trend of mass market receivers chipset and software receiver. The objectives of Location Based Services and personal mobility receiver are: low cost, small size and weight, low power. We consider here the problem of selecting the bandwidth for a high sensitivity navigation receiver engineering. A prototype design for a high sensitivity Galileo/GPS dual-model receiver is presented. The bandwidth selection is the key point of this receiver. The memory space, output SNR (signal noise ratio) loss and ranging error are analyzed using the Monte Carlo simulation and theoretic method. The trade-off optimum bandwidth alleviates contradictions.
