Abstract

The tracking bias is caused by two reasons: one is the distortion in symmetry of correlation values and the other is the shift of the point of time of the maximum correlation value. In band-limited multipath environments, the latter one is a more dominant error factor than the former one. This paper will mention about the characteristics of the coherent correlation values in band-limited multipath environments, and present the novel tracking bias mitigation scheme for a global navigation satellite system (GNSS) which is one of the location determination technologies (LDT) for positioning.
