Abstract

The performance of the GPS based vehicle navigation will be degraded in the attenuated signal environments and reflected conditions. In this paper two types of sensor fusions are proposed to improve the reliability of GPS navigation in such environments: (1) the integration of GPS with other GNSS, including GLONASS and GALILEO, and (2) the integration of GPS with low-cost INS. Numerical results demonstrate that both methods will significantly improve the robustness and accuracy when the number of tracked GPS satellite is insufficient to generate reliable results.
