摘要:
A positioning method for a navigation apparatus and the navigation apparatus are provided. The positioning method includes steps of receiving a Global Positioning System (GPS) signal; reading a previous position-velocity-time (PVT) data; reading a previous map matching (MMT) result; and computing current PVT data according to at least one of the previous PVT data and the previous MMT result.
