METHOD OF WEIGHTED GPS+GLONASS SINGLE-POINT POSITIONING
Hu Guorong\ Cui Weihong (Institute of Remote Sensing Applications, Chinese Academy of Sciences, Beijing,100101)
It is well known that the precision of GPS observations is different from that of GLONASS. Therefore, the correct determination of the weights of observations is vital for a combined GPS/GLONASS positioning. In this paper, the method of weighted GPS+GLONASS single point positioning based on posteriori estimation was proposed, which is more reasonable than weighting on the basis of experience. The method can be extended to apply in relative positioning using pseudo range or carrier phase observations.
