This paper discusses the advantages on GNSS signal receivers. In order to exert the advantages of the potential it is need to solve carefully for the following research questions: to analyze in detail the differences between the constellations, and it is necessary to handle carefully the differences between different navigation signals, timing system and coordinate system; to extract the junctions between satellite navigation signals for seeking the public frequency source of the receivers; to develop the built-in software for the receivers that is used to select an optimum positioning constellation, so as to get a smaller GDOP value, improving the accuracy of 7-dimensional status parameters measured.
