Summary Intelligent Transport System applications require accurate and reliable positioning. When stand-alone global positioning system (GPS) is used in urban areas, the results dramatically degrade, because of signal outages and multipath. This pape

Network RTK generally uses a linear interpolation method by using the corrections from reference stations. This minimizes the spatial decorrelation error caused by the increase of distance between the reference station's baseline and user's baseline.

Network RTK generates spatial corrections by using differenced measurements from reference stations in the network, and the corrections are then provided to a rover. The rover, generally, uses linear interpolation, which assumes that the corrections

In this paper, an enhanced method for attitude determination is proposed for systems using an IMU (Inertial Measurement Unit). In attitude determination with IMU, it is generally assumed that the IMU can be located in the center of gravity on the veh

Substantial interest has been given to algorithms that track multiplex binary offset carrier (MBOC) signals to be transmitted by Galileo and modernized GPS satellites, because such signals may cause a false lock in a receiver. In this paper, we propo
