Using the combination of some constellations, the multimode navigation receiver can receive the signals of some kind of satellite system. This combined positioning technology advances the reliability of the system, and the precision for positioning and time service. So, the dependency on the singular navigation system is reduced. Firstly, this paper is to give brief introduction to the situation of the satellite navigation positioning system and compare GPS, Beidou and GLONASS and the signal system of Beidou and GLONASS. Besides, the methods and principles of the combined navigation positioning, based on Beidou and GLONASS, are studied, because of the disadvantages of the Beidou positioning system lacking in resource. Secondly, the process of baseband research and implement for BD/GLONASS satellite receiver is described. Some algorithms, like Viterbi decode, data check, are researched concretely. Thirdly, hardware platform and software design of the receiver are discussed. Finally, the advantages of combined navigation are brought forward and the content of this paper is summed up. And then, some useful recommedations are proposed.
